摘要
聚集诱导发光(AIE)材料,以其优异的固态发光性能具有重要的实际应用价值。三苯胺是合成聚集诱导发光分子的常用构筑单元,通过傅克酰基化反应,制备了具有AIE活性的三苯胺衍生物(DTO)。DTO在聚集态具有明亮的橙黄色荧光,并且可以实现对爆炸物二硝基甲苯(DNT)的有效检测,同时,其固体粉末表现出明显的压致变色性质。
Aggregation-induced emission(AIE)materials have important application potential due to their excellent solid-state luminescence properties.Triphenylamine is a common building block for the synthesis of AIE molecules,in this work,a sample AIE-active triphenylamine derivative(DTO)was prepared by a one-step Friedel-Crafts acylation reaction.DTO shows bright orange-yellow fluorescence in the aggregated state,and can detect explosive DNT effectively.At the same time,its solid powder displays obvious mechanochromic properties.
