摘要：
1,3-Alternate calix[4]arenes, decorated with four nonpolar 'all-trans' tetracyclic nuclei and cation-stabilizing beta-methoxyethoxy appendages, were synthesized from commercially available starting materials and through straightforward functional groups transformations/couplings. Their Na+-transport activities, when compared with those exerted by the known conformationally-rigidified 1,3-alternate calix[4]-arene AB/cis cholic acid conjugates, suggest that the cation conductance is related to the morphology of the pendant steroids.
