Abstract:
Two simple turn-on fluorescent probes, containing a benzothiazole and the 2,4-dinitrobenzenesulfonyl group, were designed for detecting H2S. Two probes exhibited good selectivity and high sensitivity, which were applied to detect the H2S in real water samples. Probe P2 with a positive charge had better solubility than probe P1 in water; therefore, probe P2 was successfully applied to detect both the endogenous and exogenous H2S in lysosomes of living HeLa cells.
