The synthesis of picolyl-armed 1,3-alternate calix[4]areneazacrown ethers was discussed. 2-picolyl-armed calixazacrown ether showed the highest selectivity for silver ion, based on two-phase extraction, bulk liquid membrane, H nuclear magentic resonance (NMR) and solid state studies on the ligand-metal complexation. This effect was due to electrostatic interaction through effective three-dimensional encapsulation assisted by the nitrogen atom of the 2-picolyl group.
