Description

Fluorescent and colorimetric recognition properties of 2-(4-N-phenyl-3-thiosemicarbazone)-8-hydroxyquinoline (1) in buffered aqueous solution (1% DMSO, HEPES 20 mM, pH = 7.4) have been examined. Sensor 1 displays highly selective and sensitive recognition to Cu2+ with fluorescence 'ON-OFF' performance. The in situ formed 1-Cu2+ complex exhibits an excellent selectivity toward sulfide ions with fluorescence 'OFF-ON' behavior via Cu2+ displacement approach. Thus, relay recognition of Cu2+ and sulfide by a known molecule 1 has been achieved
