摘要：

The recognition ability of pyridinyl hydrazone derivatives of cone- and 1,3-alternate tetrathiacalix[4]arenes towards transition and alkali metals has been investigated by picrate extraction method. The stoichiometry of complexes and the extraction constants have been determined. It has been found that hydrazones do not extract alkali metal ions but show an excellent affinity towards transition and heavy metal cations. The removal of tert-butyl groups from calix[4]arene platform in the case of cone and 1,3-alternate isomers leads to an increase of d-ion extraction selectivity or efficiency.
