合成了 1 ,4 -二 -2 -[N,N′-二 ( 2 -胺乙基 )丙二酰胺 ]对二甲苯 ,并进行了元素分析、红外光谱、核磁共振谱表征 .在 ( 2 5.0± 0 .1 )℃ ,I=0 .1 mol·dm- 3KNO3条件下 ,用 p H法测定了该配体的质子化常数、配体与 Cu( ) ,Zn( ) ,Ni( ) ,Co( )分别形成双核二元体系的稳定常数 ,以及 Cu( ) -L-α-氨基酸 / 5-取代邻菲罗啉双核三元体系的稳定常数 .实验结果表明 ,在 Cu( ) -L-α-氨基酸 / 5-取代邻菲罗啉双核三元体系中均存在良好的直线自由能关系 .将直线自由能关系拓宽到双核配合物领域 ,并从结构上讨论了所研究双核三元体系存在线性关系的原因 . 1,4 - di - 2 - [N, N’- bis (2 - aminoethyl) malonamide] p - xylene was synthesized and characterized by elemental analysis, IR and NMR. The protonation constants of the ligands were determined by the p H method under the conditions of 0 ± 1, 1 ℃ and 1 = 0. 1 mol · dm-3KNO3. The ligands reacted with Cu (superscript 2 +), Zn () Respectively, and the stability constant of Cu () -L -α-amino acid / 5-substituted 1,10-phenanthroline binuclear ternary system.The experimental results show that in the Cu () -L- α - amino acid / 5-substituted 1,10-phenanthroline binuclear ternary system, the relationship between the straight line free energy has been broadened to that of the binuclear complex, and the existence of linearity of the studied binuclear ternary system The reason for the relationship.
