通过分光光度技术研究了溶剂对红色（C-内消旋-和红色（C-rac-5,5,7,12,12,14-六甲基-1,4,8,11-四氮杂环十四烷）铜（II）与Cl-、Br-、I-和N3-在二甲基甲酰胺、二甲基亚砜、甲醇和水中的轴向连接常数的影响。连接常数按 KH2OKdmso < Kdmf < KMeOH 的顺序变化。得到了有机溶剂和水溶剂中阴离子溶剂化的相对自由能与这些溶剂中铜(II)大环配合物的配体加成的相对自由能之间的线性关系。
The effect of solvent on the axial ligation constants of red (C-meso- and red (C-rac-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetra-azacyclotetradecane)copper(II) complexes with Cl–, Br–, I–, and N3– in dimethylformamide, dimethyl sulphoxide, methanol, and water has been studied by spectrophotometric techniques. The sequence for the axial ligation constants varies in the order KH2OKdmso < Kdmf < KMeOH. A linear relationship between the relative free energies of solvation for the anions in organic and aqueous solvents and the relative free energies of ligand addition to copper(II) macrocyclic complexes in these solvents was obtained.
