A benzothiazole-derived fluorescence enhancement probe (FL) for the detection of H2S was synthesized and characterized by employing azide group as the recognition unit, and its spectral properties had been researched. The results showed that FL exhibited relatively good sensitivity and selectivity to H2S as well as fast response, it also had strong anti-interference ability and low cytotoxicity, the detection limit of H2S was estimated to be 8.78×10-7 mol·L-1, and the detection of H2S in living HeLa cells and various water samples indicated that it had potential application value.

Key words: H2S, fluorescent probe, azide group, visualization
