Aggregation-Induced Emission: Research Trends and Impact

Background

Light, the significant momentum for human evolution and civilization, has been explored by countless scientists throughout the centuries, resulting in many landmark theories and technologies in the history of scientific research. The concept of Aggregation-Induced Emission (AIE), first proposed by Dr. Ben Zhong Tang's team in 2001, has created an emerging field of study led by Chinese scientists, which has not only broken the classical textbook assertion that aggregation leads to quenching of luminescence but also promoted the deep development of this technology in chemistry, materials science, biomedicine, and other fields. Moreover, it shifted the scientific research paradigm from reductionism to holism, giving rise to a new area of science - aggregation science. In two decades, AIE has rapidly grown into a global hot frontier, attracting the attention of numerous research teams worldwide.
