摘要:

合成了两个8-羟基喹啉取代的双功能二氧四胺大环配体L1L2,并在25℃下研究了Cu-大环配体-α-氨基酸三元体系的热力学稳定性.根据实验数据对滴定体系物种的构型进行了分析和指认,并发现Cu(Ⅱ)-8-羟基喹啉-α-氨基酸三元体系中也存在良好的直线自由能关系.

Abstract:

Two 8-hydroxyquinoline substituted dioxotetraamine macrocycles, L1 and L2, have been synthesized and their association constants with metal complexes in aqueous solution have been studied. At 25.0 ±0.1℃,I=0.1mol·dm-3 NaNO3,the stability constants of the ternary system: Cu(Ⅱ)-L(L1 or L2)-α-amino acid were investigated and the appropriate structures with respect to the titration species were proposed according to the literature and the obtained data.. The results show that good linear-free-energy relationship exist in the ternary systems.

Key words: dioxotetraamine macrocycle, functionalization, stability, linear relationship
