With recognition of the biological significance of H2S, we have designed and synthesized a novel ratiometric and colorimetric fluorescence probe, CR-DNP based on a H2S induced thiolysis reaction as well as the fluorescence resonance energy transfer process. It displayed some desirable properties, such as good photostability, high selectivity and excellent sensitivity. Also, a considerably fluorescence enhancement (15-fold) and distinct visible color change (colorless to bright orange) was observed. A good linear relationship between the emission intensity ratios and NaHS concentrations suggested that it can detect H2S quantitatively with a detection limit as low as 0.4 μM. Furthermore, due to its biocompatibility, the sensor could easily permeate through the cell membrane and trace the intracellular H2S levels change.
