Abstract
A fluorescent chemosensor has been developed for discriminative detection of phosgene and a nerve agent mimic diethyl chlorophosphate (DCP), which was comprised of an anthracene-carboxyimide fluorophore and o-phenylenediamine (OPD) reaction site. Upon phosphorylation of OPD, the chemosensor displays an obvious fluorescence turn-on response toward DPC at S88 nm with instant response and a low detection limit (88 nM). By contrast, the chemosensor exhibits a colorimetric and fluorescence enhancement response at 500 nm toward phosgene with fast response (<2 min), high selectivity, and a low detection limit (72 nM). Furthermore, chemosensor-loaded test membrane was fabricated for real-time, portable and efficient discriminative detection of trace amounts of gaseous phosgene and DCP vapor with different optical responses.
