摘要
合成了含多胺的邻菲罗啉桥联配体 ( L) ,并在 2 5℃ ,I=0 .1 mol/ LKNO3 的溶液中测量了其质子化常数 ,以及配体与二价过渡金属离子 Cu( ) ,Ni( ) ,Co( ) ,Zn( )和 Mn( )的二元稳定常数 .通过对配体与不同金属离子形成的配合物的稳定性比较发现 ,配位情况符合
The phenanthroline-containing polyamines ligand has been synthesized. The protonation process of L was determined by pH titration, UV-vis and 1H NMR. The stability constants of complexes of Mn(Ⅱ)?Co(Ⅱ)?Ni(Ⅱ)?Cu(Ⅱ)and Zn(Ⅱ)were measured by potentiometric pH titration. The competition between the electron-sufficient amino nitrogen atoms and aromatic phenanthroline which were linked together with a methylene group was discussed.
