摘要：

A series of novel calix[4]arene hydrazone and semicarbazone based neutral receptors have been synthesized and characterized by IR, UV-vis, and NMR spectroscopies. The preliminary UV-vis and H-1 NMR titration experiments revealed that 25,26,27,28-tetrapropoxycalix[4]arene tetra-semicarbazone can recognize H2PO4- through a 1: 1 binding-stoichiometry in preference over other anions (Cl-, Br-, F-, HSO4-, ClO4-, and CH3COO-).
