Herein, an aggregation-induced emission (AIE)-based sensor, 4-(1,2,2-triphenylvinyl)benzoxime (TPE-phos), has been rationally designed for phosgene detection. The sensor has a tetraphenylethylene unit combined with an oxime moiety. TPE-phos undergoes nitrile formation after the oxime group reacts with phosgene, which will give a significant "light-up" fluorescence due to the AIE effect within seconds.
本文设计了一种基于聚集诱导发光（AIE）的传感器 4-(1,2,2-三苯基乙烯基)苯甲肟（TPE-phos）用于检测光气。该传感器具有一个四苯乙烯单元和一个肟部分。TPE-phos 的肟基团与光气反应后会形成腈，由于 AIE 效应，几秒钟内会产生显著的“点亮”荧光。
