A rapid and selective “on–off” fluorescence detection of lethal pulmonary agent phosgene supplemented with theoretical approach: a cost-effective sensing tool for household bleach and soil analysis

A fluorescent probe, 4-(di-phenylamino)-benzaldehyde oxime was developed for the selective “on–off” fluorescence detection of lethal phosgene with the dimer formation of probe through carbonate linkage generated from phosgene.
