Abstract The development of organic luminescent materials has greatly affected the progress of materials science and its application.Aggregation-induced emission (AIE) has become an indispensable mainstream effect in all luminescent systems. As an anti-ACQ phenomenon, strong emission in AIE aggregation state effectively solves the ACQ problem, thus widening the practical application of luminescent materials in various fields. AIE molecules have highly distorted structures and diverse properties. Their molecular structure design and material preparation process are continuously optimized, and fluorophores with AIE effect are also continuously updated iteratively. So far, researchers have found many luminescent mechanisms of AIE, but the intrinsic luminescent mechanisms of some AIE materials still need to be further explored and specified. In addition, researchers are committed to developing high-quality new AIEgens, improving functional AIE polymers, and detecting the specific recognition of analytes, etc. with great progress, which provides more guarantee for the practical use of AIE materials. In recent years, the new mechanical understanding of AIE molecules has been generally recognized. Researchers have developed more AIE compounds with new structures. AIE has been successfully introduced into the supramolecular field through clever design, realizing the functionalization of polymer luminescent materials. At present, AIE molecules have been successfully used as fluorescent probes for chemical/biological sensing and imaging and luminescent materials for organic light emitting diodes (OLED).
This paper introduces the research progress of aggregation-induced emission, as well as fluorescent molecules designed based on AIE characteristics in recent years and describes their structural design ideas. It also briefly expounds the frontier applications of AIE materials in the fields of biological detection, medical treatment, photoelectric and so on, providing reference for researchers.
