A novel turn-on fluorescent probe, which coumarin-fused coumarin was used as fluorophore to link with 2, 4- dinitrodiphenyl ether moiety that has high selectivity and sensitivity for H2S and thiols, was designed and synthesized. Our probe YB can sensitively react with H2S and GSH to release free fluorophore with strong fluorescence signals. The probe YB could use as a significant molecular imaging tool to study the endogenous GSH in living cell and a practical detector for H2S in the papermaking wastewater.
