A benzimidazole-based imine linked receptor was synthesized for fluorescent recognition of Cu 2+ in a CH 3CN/H 2O (8:2, v/v) solvent system. The receptor offers an opportunity for the selective estimation of Cu 2+ in the presence of another metal ion at equimolar concentration. The Cu 2+ complex with the receptor acted as a sensor for a phosphate anion, and the phosphate recognition event restored the fluorescence intensity of the receptor.
