A Cu2+-sensitive fluorescent probe P based on naphthalimide derivative was designed and characterized. Study showed that P had good selectivity to Cu2+ among the tested metal ions. The fluorescent intensity was proportional to the concentration of Cu2+ in the range of 1.5×10-6-7.0×10-6 M with a detection limit of 5.0×10-7 M Cu2+. The possible binding mode of P with Cu2+ was also proposed.
