本文报道了五种新型四吡唑大环化合物的合成, 探讨了它们对Li^+, Na^+苦味酸盐的CH2Cl2液膜传递性能以及对Ru(Ⅱ)离子的配位作用。实验结果表明, 这类大环配体对两种碱金属离子具有较高的液膜传递速度; 与Ru(Ⅱ)的配合物中除四个吡唑环参与配位外, 另有一分子DMSO和分子H2O从轴向与Ru(Ⅱ)配位, 形成稳定的八面体配位结构。

It is well known that polypyrazolic macrocycles can complex with both alkali and transition metal ions. In this paper, five new functional lateral chain containing tetrapyrazolic macrocycle ligands were synthesized and their liquid membrane transport properties for Li and Na picrate and the complexation abilities with Ru (Ⅱ) were also studied. Each of the ligands can form stable octahedral complex with Ru (Ⅱ), in which one molecule of DMSO and one molecule of H2O act as axial ligands. These ligands prossess good properties for transport of Li^+ or Na^+ through dichloromethane.
