Four new receptors containing pyridio[2,3-d]pyrimidines were synthesized via three-component reaction of 6-aminopyrimidine, substituted benzaldehydes and malononitrile. The properties of the receptors with anions such as F-, Cl-, Br-, AcO-, HSO4- and H2PO4-were examined by UV-Vis spectroscopy. The results showed that receptors have good selectivity to AcO-. However, no obvious changes were observed on the other anions. The Job plot indicated that a 1:1 stoichiometry complex was formed between receptors and anions. The results also showed that hydrogen-bonding interaction was formed between the receptors and anions. The combination assumed above was confirmed by the results of 1H NMR titration.

Key words: pyridio[2,3-d]pyrimidines, anion recognition, hydrogen-bonding interaction
