The synthesis of 13 new macrocyclic polyether-diester ligands containing the furan, 3,4-dimethoxyfuran, tetrahydrofuran, and thiophene subcyclic by the reaction of a diacid dichloride with the appropriate glycol is described. The complexation properties of these ligands with alkylammonium and metal cations were determined and compared with the crown ethers. The free energies of activation (..delta
