A novel colorimetric and long-wavelength fluorescent probe (SR) based on seminaphthorhodafluor dye was designed and synthesized, which was used to detect H2S through the thiolysis reaction of dinitrophenyl ether and unique OFF-ON mechanism based on the spiro-ring of probe SR. The fluorescent intensity (635 nm) and absorbance (590 nm) changes exhibited an excellent linear relationship with the H2S concentration ranging from 2.00 to 10.00 μmol/L and the detection limits were 0.50 and 1.00 μmol/L, respectively. Ions interference experiments showed that probe SR had an excellent anti-interference ability and could be used to detect H2S in complex systems. The probe SR was further exploited for filter paper, hydrogel and Hela cells for the rapid and convenient detection of H2S, which extended the applications of fluorescent probes for the detection of H2S in chemistry and the environment.
