摘要: 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(25.0±0.1)℃,I=0.1mol/LNaNO3条件下,用pH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,并从滴定数据讨论了物种的可能构型.

关键词: 二氧四胺, 8-羟基喹啉, 稳定常数, 超分子配合物

Abstract: 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 NaNO3, the thermodynamic properties of such supramolecular coordination compounds formed by the ligand with met al ions in aqueous solution were studied by pHtitrations and structures of coordination species were also suggested.

Key words: Dioxotetraamine, 8-Hydroxyquinoline, Stability constants, Supramolecular complex
