Abstract: A new naphthalimide derivative was synthesized and characterized as Al3+-selective fluorescent probe. Study showed that this probe has good affinity and sensitibity towards Al3+ compared to other common metal ions, and the addition of Al3+ triggered a prominent fluorescence enhancement at 439 nm in ethanol phase. With the optimized experimental conditions, the probe exhibited a dynamic response range for Al3+ from 1.010-6 M to

5.010-6 M with a detection limit of 4.110-7 M.

 

Keywords: Fluorescent probe, Al3+, Schiff base, Cell imaging, Synthesis.
