Single molecular multianalyte signaling of sulfide and azide ions by a nitrobenzoxadiazole-based probe†
Abstract
Sulfide- and azide-selective optical signaling using a single nitrobenzoxadiazole (NBD)-based probe was investigated. NBD-pivalate showed colorimetric signaling for sulfide ions via cleavage of the NBD–O bond to generate NBD–SH. It also showed chromogenic and fluorogenic signaling for azide ions by O–COBut cleavage to yield NBD–OH under the same conditions.
