The results showed that hydrogen2bonding complexes were formed between receptors and anions , which turned the solution to yellow from colorless. It was found that the selectivity of receptors to anion could be efficiently tuned by increasing solvent polarity or by substitution at the N2benzoyl moiety. The recognition mechanism and binding mode were discussed and the anion recognition was successfully applied to inorganic CH3CO2NH4 in 10 % H2O2CH3CN. These findings are expected to be of significance for designing and developing novel color2based anion sensors operated in aqueous solution.zh_CN
