Through an intramolecular nucleophilic substitution reaction and ESIPT mechanism, we designed and synthesized a fluorescent hydrogen sulfide probe with a large turn on fluorescence signal (400-fold). The new probe exhibits high selectivity, good membrane-permeability and is suitable for the visualization of exogenous and endogenous hydrogen sulfide in living cells.
