摘　　要：A novel, fluorescent probe was synthesized from 2,4-dihydroxybenzaldehyde and 8-hydroxyquinoline for sensing Cu2＋ by the naked eye. The structure was confirmed by 1R, MS, 1H NMR, 13C NMR and the spectral properties of the probe were investigated. It exhibited strong fluorescence responses toward Cu2＋ and high selectivity over other metal ions. The binding constant between the probe and Cu2＋ was calculated using Benesi-Hildebrand equation.A novel, fluorescent probe was synthesized from 2,4-dihydroxybenzaldehyde and 8-hydroxyquinoline for sensing Cu2＋ by the naked eye.
