通过在杯[4]芳烃的下边缘引入两个位置相反的4，4 ′-二羧基-2，2 ′-联吡啶单元，制备了水溶性杯[4]芳烃基荚状配体。配位和亲水性的结合有利于铜离子在水中的络合和增溶，即使在牛血清白蛋白存在下也是如此。配体及其相应的CuI络合物已被充分表征，但迄今为止结晶它们的尝试一直不成功。由于这个原因，有机溶剂可溶的四酯中间体的双核ZnCl 2络合物已经结晶，并进行X射线衍射分析，证实了配体的预期豆荚状结构。（© Wiley-VCH Verlag GmbH & Co. KGaA，69451魏因海姆，德国，2004）
A water-soluble calix[4]arene-based podand has been prepared by incorporation, at the lower rim, of two 4,4′-dicarboxy-2,2′-bipyridine units in opposite positions. The association between its coordination and hydrophilic properties were beneficial to the complexation and solubilization of copper(I) in water, even in the presence of bovine serum albumin. The ligand and its corresponding CuI complex have been fully characterized, but attempts to crystallize them have been unsuccessful so far. For this reason, the dinuclear ZnCl2 complex of the organic solvent soluble tetraester intermediate has been crystallized, and subjected to X-ray diffraction analysis, confirming the expected podand-like structure of the ligand.
