Herein, a novel fluorescent probe by integrating 4-azide-1,8-naphthalic anhydride and spiropyran was obtained. NT-N3-SP was capable of specifically monitoring H2S by azide reduced. Upon irradiation by alternate ultraviolet and visible light, both the structure and emission of spiropyran moiety in NT-N3-SP can be reversibly tuned. Importantly, the alternation will be interrupted in the presence of SO2. Additionally, NT-N3-SP was successfully used for detection of H2S/SO2 in cells and mice.
