A fluorescent probe derived from naphthalimide was successfully synthesized and characterized as an “off-on” type Cu2+-selective fluorescent probe. A prominent fluorescence enhancement at 430 nm was observed in the presence of Cu2+ in ethanol-water solution (5:5, v:v, pH 6.8, 50 mM HEPES). With the optimized experimental conditions, the probe exhibited a dynamic response rangeof 7.0×10-7-9.0×10-6 M for Cu2+, and the detection limit is2.3×10-7 M.
