四苯基乙烯室温发光液体材料的制备与表征

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。

Abstract： 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.

Keywords： room-temperature luminescent liquid； aggregation-induced emission； tetraphenylethylene
