Synthesis of Indeno[2 ',1 ':5,6]pyrido[2,3-d]pyrimidine Derivatives and Their Recognition Properties as New Type Anion Receptors

[摘要]：A new type anion receptors containing indeno[2',1':5,6]pyrido[2,3-d]pyrimidine have been synthesized via three-component reaction of aldehyde, 6-aminopyrimidine-2,4-dione, and 1,3-indanedione in aqueous media. The binding properties of the receptors with anions such as F-, Cl-, Br-, AcO-, HSO4-, and H2PO4- have been investigated by UV-vis spectroscopy methods. The results have shown that receptors have good selectivity to F- and AcO-, and a 1:1 stoichiometry complex has been formed between compounds and anions.
