Abstract

A benzimidazole-based receptor that selectively recognized Cr ³⁺ without interference from other metal ions was synthesized in this study. The resultant Cr-complex recognized HSO4- and F ^- via two approaches. HSO4- ions bound to the metal center, causing changes in the fluorescent spectra at different wavelengths, whereas F ^- ions displaced Cr ³⁺, thereby switching ON the fluorescent spectra at the same wavelength.
