摘要：

A series of novel 1,3-alternate calix[4]arene-azacrown ethers with 2-picolyl, 3-picolyl, and benzyl groups on the nitrogen atom were synthesized by reaction of 1,3-alternate calix[4]arene-azacrown ether and aryl halide in the presence of triethylamine as base. Based on two-phase extraction; bulk liquid membrane, H-1 NMR, and solid-state studies on this ligand-metal complexation, 2-picolyl-armed calixazacrown ether showed the highest selectivity for silver ion due to electrostatic interaction through effective:three-dimensional encapsulation assisted by the nitrogen atom of the 2-picolyl group.
