以对叔丁基杯[4]芳烃和烷基为酯基的磷酸二酯（2a、2b和2c）在溶液中以锥型和偏锥型平衡构象存在，选择性地传输Li+;然而，在溶液中，2a作为甲酯和/或2b作为乙酯的Li和Na络合物中的杯[4]芳烃部分的构象仅为锥形，尽管K络合物的构象是锥构象和部分锥构象的混合物。
Phospate diesters, 2a, 2b and 2c, having p-tert-butylcalix[4]arenes and alkyl groups as ester moieties exist as an equilibrium of cone and partial-cone conformations in solution and selectively transport Li+; however, the conformations of the calix[4]arene moieties in the Li and Na complexes of 2a as the methyl ester and/or 2b as the ethyl ester in solution are cone only, although that of the K complex exists as a mixture of cone and partial-cone conformers.
