摘要
聚集诱导发光(AIE)自被发现以来就受到了研究者们的广泛关注,其中具有高效、长寿命的有机磷光材料表现出优异的发光性质和丰富的可调控性,是未来有机发光材料的重要发展方向.多硫芳烃化合物是一类典型的聚集诱导磷光(AIP)材料,具有高度可扭曲的分子结构和丰富的修饰位点,目前已发展出多个以此类化合物为基础的发光体系,在溶液态、薄膜态、晶体态中表现出独特的光物理性质.同时,多硫芳烃化合物在激发态表现出特有的分子构象转变,这一属性为原位光控下的分子自组装形态和发光性质调控提供了结构基础,也为开发出多功能发光体系提供了条件.旨在总结不同系列的多硫芳烃化合物在多种调控方式下的聚集诱导磷光性质,结合本课题组在这方面的研究实践,综述了近年来多硫芳烃体系的AIP性质研究,并对其目前研究中可能存在的问题提出简要展望,希望能为AIP材料的未来发展方向提供一些借鉴和思考.
Aggregation-induced emission(AIE)has received extensive attention in the field of optical materials since its discovery.Organic phosphorescence with high efficiency and long lifetime exhibits excellent luminescent properties and high flexibility of modification,which is an important development direction of organic light-emitting materials in the future.Persulfurated arenes as a typical class of aggregation-induced phosphorescence(AIP)materials possess highly twistable molecular structures and abundant modification sites.Therefore,a number of luminescent systems(such as solution state,thin film state,crystalline state,etc.)based on these compounds have been developed.At the same time,persulfurated arene exhibit a unique molecular conformation transition in the excited state,which not only provides a theoretical basis for the regulation of molecular self-assembly morphology and luminescence properties under in situ photocontrol,but also builds a fabulous platform for developing abundant luminescence systems.This paper aims to summarize the aggregation induced phosphorescence properties of different series of persulfurated arenes under various regulation modes.Combined with the research practice of our research group in this field,the AIP properties of persulfurated arenes in recent years are reviewed.The possible problems in the current research are briefly prospected,hoping to provide some reference and thinking for the future development direction of AIP materials.
