Abstract

A novel quinolone-based fluorescent chemosensor 1 was designed and synthesized for hydrogen sulfide. Distinct “turn-on” fluorescence enhancement of 1 was observed upon the addition of S^{2 −} in aqueous solution. Sensor 1 showed high sensitivity toward S^{2 −} with the detection limit of 7.0 μM. The recognition properties of sensor 1 toward S^{2 −} were studied by using photophysical experiments and its reaction-based sensing mechanism was supported by ESI-mass spectroscopy analysis. Practically, the sensing ability of 1 for S^{2 −} was successfully applied in real water samples.
