摘要/Abstract

摘要： 采用Wittig-Horner反应合成了两种具有聚集诱导发光(AIE)性能的乙烯基衍生物.紫外及荧光光谱显示,两种化合物在聚集态时分子间的π-π相互作用很弱,二者在聚集态时都展示了很强的荧光增强发光性能.由于二者所具有的扭曲的分子构型提供了2,4-二硝基甲苯(DNT)气态分子扩散所需的分子通道,因此对DNT蒸气的检测均显示了较高的荧光猝灭效率,且其荧光猝灭具有较好的可逆性.

关键词: 硝基芳烃, 聚集诱导发光, 三苯胺, 荧光猝灭

Abstract: Two vinyl derivatives with AIE properties were synthesized by Wittig-Horner reaction. The UV and fluorescence spectroscopy shows that the two compounds have weak π-π interactions in the aggregation state. Both of them showed strong enhancement fluorescence luminescence properties in the aggregation state. The distortion of their molecular configuration made the diffusion of DNT vapor molecules to the film easier, so the films have shown higher fluorescence quenching efficiency to DNT, and their fluorescence quenching toward DNT is reversible.

Key words: nitroaromatic, aggregation induced emission, triphenylamine, fluorescence quenching
