An AIE fluorescent sensor for rapid and selective detection of phosgene

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.

Automated summary

In this study, a sensor based on aggregation-induced emission (AIE), named 4-(1,2,2-triphenylvinyl)benzoxime (TPE-phos), was designed for phosgene detection. The sensor undergoes nitrile formation after reacting with phosgene, leading to significant fluorescence emission within seconds due to the AIE effect.
