Research Progress of Aaggregation-induced Emission Materials Based on Diarylethylene

荧光染料作为一种重要的化工原料,在纺织染料、印刷颜料、防伪显色和医疗检测等领域得到广泛应用。随着科研发展,多重刺激响应荧光材料由于结构可调性和功能可控性而备受关注。传统的荧光材料由于在聚集态会荧光猝灭使应用受限,而聚集诱导发光(AIE)材料由于聚集态荧光增强的优点在荧光探针、加密防伪和分子开关等方面得到广泛研究与应用。随着科技进步和社会需求的提高,功能单一的聚集诱导发光材料逐渐落伍,开发功能多样的AIE材料已成为众多科研人员的研究热点。具有光响应和AIE特性的多功能分子具有很高的理论研究价值和应用潜力。二芳基乙烯是最重要的光致变色化合物。将二芳基乙烯基团引入聚集诱导发光材料,使材料具有独特的聚集诱导发光行为和光致变色活性,这对于开发多功能的荧光化工染料具有重要意义。本文介绍了基于二芳基乙烯的聚集诱导发光材料的研究进展,并对其结构设计思想进行描述,为研究者提供参考。

As an important chemical material,fluorescent dyes are widely used in many fields such as textile,printing pigment,printing anti-counterfeiting and biopharmaceutical.With the further development of scientific research,multi-stimuli-responsive luminescent materials have attracted more attention due to their tunable structures and controllable functions.In recent years,organic aggregation-induced emission(AIE)materials have effectively overcome the main shortcomings of traditional fluorescent materials in aggregation-caused quenching(ACQ)in solid or aggregate state,and have been widely studied and applied in biological probes,optical devices,anti-counterfeiting materials,etc.However,unifunctional AIE materials can't meet the advancement of science and technology and the increasing demands for production and life.The study of AIE molecules combined with multifunctional groups has become one of the current focused topics in the field of materials.Multifunctional AIE molecules with light-responsive and AIE properties have have great oretical value,and broad application future.Diarylethene is one of the most promising optically responsive molecu.By introducing photoactive diarylethylene group into aggregation-induced emission materials,the molecules have a unique photophysical behaviour of aggregation-induced emission and interesting photochromic activity.This is of great significance for the development of multifunctional fluorescent chemical dyes.This paper introduces the research progress of aggregation-induced emission with diarylethene group and describes their structural design ideas,providing reference for researchers.
