Synthetic receptors based on calix[4]arene functionalized at the lower rim in molecular recognition of dicarboxylic, α-hydroxycarboxylic, and α-amino acids

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 α-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 α-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

New host molecules based on the thiacalix[4]arene platform for cation recognition

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. © 2005 Springer Science+Business Media, Inc

Synthetic receptors for transition metal cations - Tetrahydrazides on the basis of p-tert-butylthiacalix[4]arene

Stereoisomers of tetrahydrazide on the basis of p-tert-butylthiacalix[4] arene have been synthesised and characterised by IR spectroscopy, 1H and 13C NMR spectroscopy and mass spectrometry; the receptor properties of novel compounds towards metal cations, including most dangerous environmental pollutants, have been characterised by picrate extraction
