  Benzimidazole-based fluorescent sensors for Cr3+ and their resultant complexes for sensing and F−

  摘要：

  A benzimidazole-based receptor that selectively recognized Cr3+ 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 Cr3+, thereby switching ON the fluorescent spectra at the same wavelength.
