Abstract
A novel fluorescent probe based on 8-hydroxy-2-methyl quinoline has been designed and synthesized to detect Cu2+ ions. The probe showed a fluorescence turn-off response for Cu2+ over other metal ions such as Na+, K+, Mg2+, Ca2+, Ba2+, Ag+, Cd2+, Zn2+, Co2+, Fe2+ and Pb2+ in CH3CN/H2O solution (v/v, 4:1, pH = 7.68) with specific selectivity and high sensitivity. The fluorescence emission of the probe was immediately quenched after addition of Cu2+ in CH3CN/H2O solution (v/v, 4:1, pH = 7.68) due to photoinduced electron transfer mechanism. The binding ratio between the probe and Cu2+ ions was determined to be 2:1.
