Abstract
•A new fluorescent chemosensor was prepared.•The chemosensor exhibits a significant fluorescent enhancement toward Al3+ in ethanol.•In the presence of Al3+, H2L exhibits significant fluorescence enhancements with a blue shift owing to CHEF.
A new naphthalene derivative receptor (H2L) was synthesized. The chemosensor (H2L) exhibited a strong fluorescence enhancement in the presence of trace amounts of Al3+, attributable to chelation-enhanced fluorescence (CHEF) effect, which also displayed high selectivity over a series of other metal cations (Na+, K+, Cs+, Mg2+, Ba2+, Pb2+, Cr3+, Mn2+, Fe3+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+ and Ag+) in ethanol.
