近年来, 有机聚集诱导发光(AIE)材料有效克服了传统荧光材料在固态或聚集态下荧光淬灭(ACQ)的主要缺陷,在生物探针、细胞成像、光学器件、防伪材料等方面得到了广泛研究与应用. 但是, 单功能的AIE材料往往满足不了科学技术发展和人们日益增长的物质生活需求. 为拓展AIE材料的应用范围, 多功能团组合的AIE分子的研究进一步成为当今材料领域的热点之一. 兼具有光致变色和AIE特性的多功能分子, 由于能够对外部刺激做出多重光响应和良好的可逆调控特性而受到了广泛关注. 根据分子中光致变色单元不同的异构化机制, 结合本课题组在这方面的研究实践, 综述了二十一世纪以来基于有机光致变色功能单元的AIE分子的主要研究进展和应用, 并对其未来发展进行了简要展望, 希望能为本领域的研究提供一些借鉴和思考.

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 cell imaging, 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 material life. In order to expand the application range of AIE materials, the study of AIE molecules combined with multifunctional groups has further become one of the current focused topics in the field of materials. Multifunctional molecules with both photochromic and AIE properties have received extensive attention due to their promising performances in reversible control and multiple photoresponses upon external stimuli and good control properties. Based on the different isomerization mechanisms of the photochromic units in the multifunctional molecules, and combined with the research practice of our group in this topic, this presentation briefly reviews the main advances and application of AIE molecules based on the different photochromic functional units since the 21st century. It also looks forward to its future development, hoping to provide some reference and thinking for the research in this field.
