摘要：

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 S2- in aqueous solution. Sensor 1 showed high sensitivity toward S2- with the detection limit of 7.0 mu M. The recognition properties of sensor 1 toward S2- 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 S2- was successfully applied in real water samples. (C) 2017 Elsevier B.V. All rights reserved.
