Hydrogen sulfide (H2S) is not only involved in the physiological regulation of human body, but also has an impact on the flavor and taste of wine. Therefore, a benzopyran derivative modified by 2,4-dinitrobenzene (DCM-dip) was synthesized, which had no fluorescence in dimethyl sulfoxide (DMSO)/phosphate buffered saline (PBS) (V:V=8:2, pH=8) solution. DCM-dip underwent a thiolysis reaction with H2S to release the intermediate with fluorescence, which showed a fluorescence turn-on response for recognition of H2S. DCM-dip recognized H2S with a response time of 20 min, a detection limit of 2.82 μmol/L, pH application range of 8~11 and a large Stokes shift (123 nm), avoiding background interference. The application research indicates that DCM-dip can be used to detect H2S in red wine and beer samples, and image for H2S in living cells.
