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

Abstract

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
