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 H2PO4via 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.
