Synthesis and characterization of a new al3+-selective probe based on Naphthalimide derivative

A naphthalimide derivative was successfully synthesized and characterized as an Al3+-selective fluorescent probe. An obvious red-shift of the signal was observed in the presence of Al3+ in ethanol solution. This proposed probe exhibited a dynamic response range for Al3+ from 1.3 × 10-6 to 7.0 × 10-6 M with a detection limit of 8.2 × 10-7 M.
