  Abstract

A new quinoline-based acylhydrazone (1) has been synthesized and applied as a fluorescent probe. Probe 1 exhibits high selectivity and sensitivity to Cu2+ with fluorescence “ON-OFF” behavior in HEPES buffered (1‰ DMSO, HEPES 20 mM, pH = 7.4) solution. The on-site generated 1-Cu2+ complex displays excellent selectivity to sulfide ions with fluorescence “OFF-ON” performance through copper displacement approach.
