摘　　要：室温发光液体是一种具有广泛应用前景的新型软物质材料,但传统有机发光液体的发光效率普遍较低。针对以上问题,将扇形烷基尾链引入四苯基乙烯发光体系,设计并合成了一种新型的四苯基乙烯衍生物,并通过紫外-可见吸收光谱、荧光光谱、热重和差示扫描量热实验对样品的自组装行为、发光性质、热稳定性和相结构进行了表征。结果表明:该四苯基乙烯衍生物具有典型的聚集诱导发光性质,且在室温下以黏稠液体形式存在,是一种新型的室温液体发光材料。Room-Temperature luminescent liquid is a new type of soft materials with wide application prospects,but the luminous efficiency of traditional organic luminescent liquid is generally low.In view of the above problem,a new type of tetraphenylethylene derivative was designed and synthesized through the introduction of fan-shaped alkyl tails.Its self-assembly behavior,luminescent property,thermal stability and phase structure were then elucidated by corresponding experiments such as UV-visible absorption spectra,photoluminescence spectra,thermogravimetric analysis and differential scanning calorimetry.The results show that the tetraphenylethylene derivative exhibits typical aggregation-induced emission property and exists as a viscous liquid at room temperature,it is a new type of room-temperature liquid luminescent material.
