Abstract
2, 6-Dibenzamide pyridinium hydrochloride (3) was synthesized and applied to recognize anions. Fluorescence spectra and UV-Vis spectra show that receptor 3 can selectively recognize fluoride through visible color change and remarkable fluorescence quenching. Job plot indicates that receptor 3 forms 1:1 stoichiometric complex with fluoride. The molecular structures of receptors and complex with fluoride were simulated by Gaussian 03. The receptor 3 combines with F- through hydrogen bond interaction including N-H ⋯ F- and (N-H)+ ⋯ F-.
