Abstract

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.
