本文合成了８－羟基喹啉取代的二氧四肢开链配体Ｌ并进行了红外、元素分析、核磁和质谱表征。在（２５ ±０．ｌ）℃，Ｉ＝０．１ｍｏｌ·ｄｍ－３ＮａＮＯ３条件下，运用ｐＨ电位滴定技术测定了双核混配体系Ｃ ｕ（Ⅱ）（或Ｃｏ（Ⅱ）-Ｌ-５-取代邻菲罗啉合铜（Ⅱ）配合物的稳定常数，并从滴定数据、物种分布曲线和文献结果对配合物可能的配位方式进行了讨论。我们发现在Ｃｕ （Ⅱ）-Ｌ－５．取代邻菲罗啉体系的质子化过程中，开链二氧四胺与Ｃｕ（Ⅱ）存在微弱配位，而邻菲罗琳和８－羟基喹啉与过渡金属离子的结合力远大于开链二氧四胺，因此在金属离子与配体比合适的情况下能稳定存在双核或异双核配位化合物。在质子化过程中，直线自由能关系尚成立而在多核混配体系中，直线自由能关系不存在，这说明在如此复杂的体系中很可能存在有趣的配体－配合物－金属离子的协同作用。
In this paper, 8-hydroxyquinoline substituted dioxygen exo-ligand L was synthesized and characterized by IR, elemental analysis, nuclear magnetic resonance and mass spectrometry. Under the condition of (25 ± 0.1) ℃ and I = 0.1mol · dm-3NaNO3, the potential distributions of C u (Ⅱ) (or Co (Ⅱ) -L- The coordination constants of copper (Ⅱ) complexes with phenanthroline and copper (Ⅱ) complexes were discussed, and the possible coordination modes of the complexes were discussed from the titration data, species distribution curves and literature results. In the protonation process of the substituted phenanthroline system, the open-chain diaminetetraamine has a weak coordination with Cu (Ⅱ), whereas the binding force of o-phenanthroline and 8-hydroxyquinoline with transition metal ions is far greater than that of the open chain Diaminetetraamine, so the binuclear or heterobinuclear coordination compounds can stably exist when the ratio of metal ions to ligand is suitable.In the process of protonation, the relation of the linear free energy is still established and in the multicomponent mixing system, the straight line is free The absence of a relationship suggests that there is likely to be a synergistic effect of interesting ligand-complex-metal ions in such a complex system.
