文摘

A novel benzimidazole based ligand (1) has been synthesized and studied its anion recognition properties. The binding of anion with 1 was studied using UV-Visible spectroscopy, fluorescence spectroscopy and 1H-NMR techniques at very low concentrations. The results obtained from the spectroscopic studies indicate that ligand 1 is an efficient anion receptor providing changes in chemical shift and optical signals for the detection of two most environmentally important anions, fluoride and cyanide.
