Popis: Constructed by coumarin fluorophore and dinitrophenyl ether moiety, a new probe CTN was synthesized for hydrogen sulfide (H 2 S) detection. The probe featured with high sensitivity and good selectivity. Compound CTO produced by the reaction of CTN with H 2 S possesses very high quantum yield. Up to 200-fold fluorescence enhancement toward H 2 S was observed and the detection limit was calculated to be as low as 90 nM. Moreover, CTN is membrane-permeable and suitable for visualization of H 2 S in living cells.
