title: 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.
