Transport of metal salts; encapsulation of anions in dinuclear Cu(ii) complexes [Cu2L2SO4]SO4and [Cu2L2BF4](BF4)3, where L = 2,2’-[1,6-hexanediylbis[(methylimino)methylene]]bis[4-tert-butyl-6-(phenylazomethinyl)phenol]
摘要:
通过简单的曼尼希缩合反应,将水杨醛亚胺单元与 2,9- 二氮杂癸烷表带高产连接起来,生成了一种配体,这种配体可形成 2 - 2 - 1 的 Cu - L - 阴离子组合体,其中阴离子被包裹在一个四阳离子空腔中。

spectroscopic studies of a dicopper(II) double helicate capable of binding anions is described. X-Ray crystallographic analysis of three anion variations of the complex have shown that the helicate is capable of accommodating anions with an approximate volume of 0.09 nm3 and smaller. ESI-MS revealed that the supramolecular complexes retain the 2 : 2 ligand : metal cluster in solution. Spectrometric analysis
