摘要
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.dm- 3 Na NO3条件下 ,用 p H法测定了配体 :金属离子 =2 :3(物质的摩尔比 )二元配合物的稳定常数 。
New C functionalized dioxotetraamine macrocycles, which contained two independent chelating groups, were synthesized through simple methods. At 25.0±0.1℃,I=0.1mol·dm -3 NaNO 3, the solution thermodynamic stability properties of such supramolecular coordination compounds formed by the ligands with metal ions were studied by pH titrations and appropriate structures of coordination species were also suggested.$$$$
