Submission declaration
Submission of an article implies that the work described has not been published previously
(except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication
elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was
carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any
other language, without the written consent of the copyright-holder.
Changes to authorship
This
policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts:
Before the
accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange the author names, must
be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a) the reason the name should
be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from all authors that they agree
with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author
being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding
author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such
requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed.
After
the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange author names in an article published
in an online issue will follow the same policies as noted above and result in a corrigendum.
Copyright
Upon
acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (for more information on this and copyright
see
http://www.elsevier.com/copyright). Acceptance of the agreement will ensure the widest possible dissemination of information.
An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement'
form or a link to the online version of this agreement.
Subscribers may reproduce tables of contents or prepare lists of articles
including abstracts for internal circulation within their institutions. Permission of the Publisher is required for resale or distribution
outside the institution and for all other derivative works, including compilations and translations (please consult
http://www.elsevier.com/permissions).

Introduction
Chinese Chemical Letters (CCL) is a monthly journal, launched by the Chinese Chemical
Society. CCL will publish preliminary accounts in the whole field of chemistry, satisfying a real and urgent need for the dissemination
of research results, especially hot topics. In a way, it has become a show window of important chemical literature of China. For this
purpose, articles in CCL are only written in English.
Retained author rights
As an author
you (or your employer or institution) retain certain rights; for details you are referred to:
http://www.elsevier.com/authorsrights.
Role of the funding source
You are requested to identify who provided financial support for the conduct of
the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection,
analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication. If the
funding source(s) had no such involvement then this should be stated. Please see
http://www.elsevier.com/funding.
Funding body agreements and policies
Elsevier has established agreements and developed policies to allow authors
whose articles appear in journals published by Elsevier, to comply with potential manuscript archiving requirements as specified as conditions
of their grant awards. To learn more about existing agreements and policies please visit
http://www.elsevier.com/fundingbodies.
Language and language services
Please write your text in good English (American or British usage is accepted,
but not a mixture of these). Authors who require information about language editing and copyediting services pre- and post-submission
please visit
http://webshop.elsevier.com/languageservices
or our customer support site at
http://support.elsevier.com
for more information.
Referees
Please submit, with the manuscript, the names, addresses
and e-mail addresses of three potential referees. Note that the editor retains the sole right to decide whether or not the suggested
reviewers are used.
Information for contributor
CCL
does not accept articles previously published or scheduled to be published. After publication of the communica-tion in CCL, it can be
expanded to a full paper and published elsewhere.
Authors are requested to send papers of 2-4 pages.
The page margin should be
that top, bottom, left and right is
4, 4, 2.3 and
2.2 cm, respectively. Formula, Tables and other graphical material should
be placed exactly within the area. Le-gends and notes should be clear, with letter size of 9 points, where “Table 1, Fig. 1”,
etc should be in 9 points.
The
title of the article should be typed with letter size of 17 points, capitalizing the first letter.
Four-line space is needed before the title. The authors’ names are listed in 13 points, with the given name first and surname (capitalizing
the first letter) last (for example An Min Lin, please note the absence of hyphen between An Min). The author or authors to whom correspondence
should be addressed by readers of the Journal and indicated by an asterisk (with an accompanying footnote). The next line is the address
including institution, city and postal code, in 9 points, italic, without all-embracing parentheses. The line space is 13 points. After
two lines of space is the abstract with the word “ Abstract” in bold, in 9 points. After one line of space are the
Keywords
(“ Keywords” in Italic), in 9 points. Then after two lines of space is the main text in 10 points.
The first line of the
paragraphs in the text should have an indentation of two letters. There is no spacing between paragraphs and the line space is 13 points.
Sectional
headings like “ Experimental” ,“Results and discussion” ,“Acknowledgment”, “References”,
etc., are in bold, in 10 points, and aligned to the left. The use of the first two headings is not encouraged unless deemed to be essential
for clarity of presentation. After two lines of space of the main text is “Acknowledgment”, “References” is one
lines of space after “Acknowledgment”.
Standard international units should be used for weights, measures and physicochemical
units, such as mol/L, r/min, kPa, h, etc. Specific rotations are to be quoted without the degree sign ( o ).
In the text all pertinent
data should be included. It facilitates evaluation of the article by the referees, and helps the reader to repeat the experiment. X-ray
diffraction analysis (refined coordinates) can not be included in the text, but should be mailed together with the manuscript to the
editor as supported information.
Together with the manuscript the author also may mail some materials such as data or background of
the work which are not contained in the text. This will be helpful for the referees, and hence may shorten the evaluation process.
Use of wordprocessing software
It is important that the file be saved in the native format of the wordprocessor
used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed
and replaced on processing the article. In particular, do not use the wordprocessor's options to justify text or to hyphenate words.
However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one
grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic
text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier:
http://www.elsevier.com/guidepublication).
Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also
the section on Electronic artwork.
To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check'
functions of your wordprocessor.
Article structure
Subdivision - numbered
sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1,
1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do
not just refer to 'the text'. Any subsection may be given a brief heading. Each heading should appear on its own separate line.
Introduction
State the objectives of the work and provide an adequate background, avoiding a detailed literature
survey or a summary of the results.
Material and methods
Provide sufficient detail to allow
the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.
Theory/calculation
A Theory section should extend, not repeat, the background to the article already dealt
with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development
from a theoretical basis.
References
Indicate references by number(s) in square brackets
in line with the text. The actual authors can be referred to and only the first three authors listed others cited as et al., but the
reference number(s) must always be given. For example, “ ...as demonstrated [3,6]. Barnaby and Jones [8] obtained a different result.... ”. Number the references (numbers in square brackets) in the list in the order in which they appear in the text.

E-Publishing, Inc., New York, 1994, pp. 281.
Results
Results should be clear and concise.
Discussion
This should explore the significance of the results of the work, not repeat them. A combined Results
and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.
Conclusions
The
main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion
or Results and Discussion section.
Appendices
If there is more than one appendix, they should
be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a
subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.
Vitae
Include
in the manuscript a short (maximum 100 words) biography of each author, along with a passport-type photograph accompanying the other
figures.
Essential title page information
•
Title.
Concise and informative.
Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
•
Author names
and affiliations.
Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors'
affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter
immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including
the country name and, if available, the e-mail address of each author.
•
Corresponding author.
Clearly indicate
who will handle correspondence at all stages of refereeing and publication, also post-publication.
Ensure that telephone and fax numbers
(with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be
kept up to date by the corresponding author.
•
Present/permanent address.
If an author has moved since the
work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as
a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address.
Superscript Arabic numerals are used for such footnotes.
Abstract
A concise and factual
abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An
abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided,
but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential
they must be defined at their first mention in the abstract itself.
Submissions
Manuscripts
should be sent directly to the Editorial Office of CCL.
http://www.chinchemlett.com.cn
E-mail:
cclbj@imm.ac.cn
Abbreviations
Define abbreviations that are not standard in this field in a footnote to be placed on the first
page of the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as
in the footnote. Ensure consistency of abbreviations throughout the article.
Acknowledgements
Collate
acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title
page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language
help, writing assistance or proof reading the article, etc.).
Math formulae
Present simple
formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g.,
X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively
any equations that have to be displayed separately from the text (if referred to explicitly in the text).
Footnotes
Footnotes
should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many wordprocessors build
footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and
present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.
Table
footnotes
Indicate each footnote in a table with a superscript lowercase letter.
Artwork
Electronic artwork
General points
• Make sure you use uniform lettering and sizing of your
original artwork.
• Save text in illustrations as 'graphics' or enclose the font.
• Only use the following fonts in
your illustrations: Arial, Courier, Times, Symbol.
• Number the illustrations according to their sequence in the text.
•
Use a logical naming convention for your artwork files.
• Provide captions to illustrations separately.
• Produce images
near to the desired size of the printed version.
• Submit each figure as a separate file.
A detailed guide on electronic
artwork is available on our website:
http://www.elsevier.com/artworkinstructions
You are urged to visit this
site; some excerpts from the detailed information are given here.
Formats
Regardless of the application used, when
your electronic artwork is finalised, please 'save as' or convert the images to one of the following formats (note the resolution requirements
for line drawings, halftones, and line/halftone combinations given below):
EPS: Vector drawings. Embed the font or save the text
as 'graphics'.
TIFF: Color or grayscale photographs (halftones): always use a minimum of 300 dpi.
TIFF: Bitmapped line drawings:
use a minimum of 1000 dpi.
TIFF: Combinations bitmapped line/half-tone (color or grayscale): a minimum of 500 dpi is required.
If
your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply 'as is'.
Please
do not:
• Supply files that are optimised for screen use (e.g., GIF, BMP, PICT, WPG); the resolution is too low;
•
Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.
Color artwork
Please make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office files)
and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure,
at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether
or not these illustrations are reproduced in color in the printed version.
For color reproduction in print, you will receive information
regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color: in print or
on the Web only. For further information on the preparation of electronic artwork, please see
http://www.elsevier.com/artworkinstructions.
Please note: Because of technical complications which can arise by converting color figures to 'gray scale' (for the printed version
should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.
Figure captions
Ensure that each illustration has a caption. Supply captions separately, not attached to the
figure. A caption should comprise a brief title (
not on the figure itself) and a description of the illustration. Keep text in
the illustrations themselves to a minimum but explain all symbols and abbreviations used.
Tables
Number
tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them
with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables
do not duplicate results described elsewhere in the article.
Citation in text
Please ensure
that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must
be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in
the text. If these references are included in the reference list they should follow the standard reference style of the journal and should
include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. Citation of a reference
as 'in press' implies that the item has been accepted for publication.
Web references
As
a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author
names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the
reference list) under a different heading if desired, or can be included in the reference list.
References
in a special issue
Please ensure that the words 'this issue' are added to any references in the list (and any citations
in the text) to other articles in the same Special Issue.
Reference management software
This
journal has standard templates available in key reference management packages EndNote (
http://www.endnote.com/support/enstyles.asp)
and Reference Manager (
http://refman.com/support/rmstyles.asp). Using plug-ins to wordprocessing packages, authors only
need to select the appropriate journal template when preparing their article and the list of references and citations to these will be
formatted according to the journal style which is described below.
Journal abbreviations source
Journal
names should be abbreviated according to
Index Medicus journal abbreviations:
http://www.nlm.nih.gov/tsd/serials/lji.html;
List of title word abbreviations:
http://www.issn.org/2-22661-LTWA-online.php;
CAS (Chemical Abstracts Service):
http://www.cas.org/sent.html.
Video data
Elsevier accepts video material and
animation sequences to support and enhance your scientific research. Authors who have video or animation files that they wish to submit
with their article are strongly encouraged to include these within the body of the article. This can be done in the same way as a figure
or table by referring to the video or animation content and noting in the body text where it should be placed. All submitted files should
be properly labeled so that they directly relate to the video file's content. In order to ensure that your video or animation material
is directly usable, please provide the files in one of our recommended file formats with a preferred maximum size of 50 MB. Video and
animation files supplied will be published online in the electronic version of your article in Elsevier Web products, including ScienceDirect:
http://www.sciencedirect.com. Please supply 'stills' with your files: you can choose any frame from the video or animation
or make a separate image. These will be used instead of standard icons and will personalize the link to your video data. For more detailed
instructions please visit our video instruction pages at
http://www.elsevier.com/artworkinstructions. Note: since video
and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and the print version
for the portions of the article that refer to this content.
Supplementary data
Elsevier
accepts electronic supplementary material to support and enhance your scientific research. Supplementary files offer the author additional
possibilities to publish supporting applications, high-resolution images, background datasets, sound clips and more. Supplementary files
supplied will be published online alongside the electronic version of your article in Elsevier Web products, including ScienceDirect:
http://www.sciencedirect.com. In order to ensure that your submitted material is directly usable, please provide the data
in one of our recommended file formats. Authors should submit the material in electronic format together with the article and supply
a concise and descriptive caption for each file. For more detailed instructions please visit our artwork instruction pages at
http://www.elsevier.com/artworkinstructions.

Use of the Digital
Object Identifier
The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists
of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication.
The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they
have not yet received their full bibliographic information. The correct format for citing a DOI is shown as follows (example taken from
a document in the journal
Physics Letters B):
doi:10.1016/j.physletb.2010.09.059
When you use the DOI to create URL
hyperlinks to documents on the web, the DOIs are guaranteed never to change.
Proofs
One
set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper
proofs will be sent by post) or, a link will be provided in the e-mail so that authors can download the files themselves. Elsevier now
provides authors with PDF proofs which can be annotated; for this you will need to download Adobe Reader version 7 (or higher) available
free from
http://get.adobe.com/reader. Instructions on how to annotate PDF files will accompany the proofs (also given online).
The exact system requirements are given at the Adobe site:
http://www.adobe.com/products/reader/tech-specs.html.
If
you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them
to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections
and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail,
or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures.
Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor.
We will do everything possible to get your article published quickly and accurately – please let us have all your corrections within
48 hours. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying,
as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed
with the publication of your article if no response is received.
Offprints
The corresponding
author, at no cost, will be provided with a PDF file of the article via e-mail. For an extra charge, paper offprints can be ordered via
the offprint order form which is sent once the article is accepted for publication. The PDF file is a watermarked version of the published
article and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions of use.
For inquiries relating to the submission of articles (including electronic submission) please
visit this journal's homepage. Contact details for questions arising after acceptance of an article, especially those relating to proofs,
will be provided by the publisher. You can track accepted articles at
http://www.elsevier.com/trackarticle. You can also
check our Author FAQs (
http://www.elsevier.com/authorFAQ) and/or contact Customer Support via
http://support.elsevier.com.
