Abstract

A benzimidazole-based dipodal receptor was designed and synthesized. The receptor recognized Cu²⁺ions selectively in an aqueous medium in the presence of other metal ions. The resultant complex displayed selective sensing ability toward H₂PO₄⁻via a metal displacement process. The detection limits of the receptor to Cu²⁺, and the resultant complex to H₂PO₄⁻, were calculated to be 9.76 and 1.41 μM, respectively. These values are sufficiently low indicating that this system shows good potential for application in biological and environmental sample analyses.
