New calix[4]arenes, di- and tetrasubstituted at the lower rim, with different functional groups were synthesized. They were studied as carriers of a series of dicarboxylic and -hydroxycarboxylic acids through a liquid impregnated membrane. The calix[4]arenes under study are capable of molecular recognition of oxalic acid in the series of structurally similar dicarboxylic and -hydroxycarboxylic acids. The regularities found make it possible to change purposefully the receptor ability of 1,3-disubstituted calix[4]arenes by variation of the nature of substituents. 相似文献

The synthesis of four new tetra-and di-carbonyl p-tert-butyl thiacalix[4]arenes is reported. The three tetracarbonyl compounds differ as conformational isomers (cone, partial cone, and 1,3-alternate). The influence of the alkali metal ion templates on the formation of the different conformational isomers of the compound was studied by the solvent extraction method. 相似文献
