Description
Summary:A new "turn-on" fluorescent probe based on 8-aminoquinoline for detection of Zn 2+ was designed, synthesized and characterized. The sensor showed excellent selectivity and sensitivity with a fluorescence enhancement to Zn 2+ over other cations in CH 3 OH-H 2 O solution. The detection limit for Zn 2+ by HAQT reached 2.56 × 10 −7 M. The binding ratio of the HAQT-Zn 2+ complex was determined to be 1 : 1 according to the Job plot. The mechanism of HAQT for the recognition of Zn 2+ has been investigated by FT-IR, 1 H NMR and MS analyses. These advantages allowed for the application of HAQT to detect Zn 2+ in real water samples. A new "turn-on" fluorescent probe based on 8-aminoquinoline for detection of Zn 2+ was designed, synthesized and characterized.
