功能取代二氧四胺大环金属超分子配合物的溶液热力学性质研究

Thermodynamic Studies on the Functionalized Substituted Dioxotetraamine Macrocyclic Super-molecular Metal Complexes in the Solution

利用简单步骤合成了 8-羟基喹啉取代的二氧四胺大环配体 ,此类配体含有两个独立的螯合基团 ,在适当情况下能分别与金属离子配位 .在 ( 2 5 .0± 0 .1 )℃ ,I=0 .1 mol/ L Na NO3条件下 ,用 p H法测定了 n(配体 )∶n(金属离子 ) =2∶ 3的二元配合物的稳定常数 。

New C functionalized dioxotetraamine macrocycles, which contained two independent chelating groups, were synthesized and characterized. At (25.0±0.1) ℃, I =0.1 mol/L NaNO 3, the thermodynamic properties of such supramolecular coordination compounds formed by the ligand with metal ions in aqueous solution were studied by pH titrations and structures of coordination species were also suggested.
