A new fluorescent probe for gasotransmitter H2S: high sensitivity, excellent selectivity, and a significant fluorescence off–on response

Abstract

A fluorescent off–on probe for H2S was exploited by coupling the azide-based strategy with the excited-state intramolecular proton transfer (ESIPT) sensing mechanism, which exhibits a considerably high fluorescence enhancement (1150-fold), an extremely low detection limit (0.78 nM), and a relatively fast response time (3–10 min) as well as excellent selectivity.
