A fluorogenic and visual probe was devised to detect diethyl chlorophosphate (DCP), a nerve agent simulant. The probe, N-(rhodamine B)-lactam-2-aminoethanol (RB-AE), undergoes oxazoline formation following phosphorylation in the presence of DCP, which gives rapid and clear fluorescence and color change in the assay solutions.

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...

A fluorescent probe bearing two functional groups was designed to discriminate fluoride-containing G and sulfur-containing V series nerve agents through reacting with fluorides and thiols, which exhibited obvious and diverse fluorescence changes.
