Five new receptors containing furo[3’,4’:5,6]pyrido[2,3-c]pyrazole core were synthesized. The properties of the receptors with anions such as F－, Cl－, Br－, AcO－, and were examined by UV-Vis spectroscopy. The results showed that the receptors have good selectivity to F－ and AcO－. However, no obvious changes were observed on the other anions. The Job plot indicated that a 1∶1 stoichiometry complex was formed between the receptors and anions. The results also showed hydrogen-bonding interaction was formed between the receptors and anions.

Key words: furo[3’,4’:5,6]pyrido[2,3-c]pyrazole, anion recognition, hydrogen-bonding interaction
