摘　　要：2-羟基-3-甲氧基-5-甲基苯甲醛分别与乙二胺、1,2-丙二胺、1,3-丙二胺、2,3-二甲基-2,3-丁二胺及邻苯二胺反应,合成出一系列二元Schiff碱型化合物.测定Schiff碱与钴(Ⅱ)离子配合后的配合物对氧分子的加合常数,讨论了结构与加合性能之间的关系.配合物中二胺-钴螯合环的刚性对配合物的氧加合性有重要影响.Five binary Schiff bases and their dioxygen-affinity cobalt (Ⅱ) complexes were synthesized from 2-hydroxy-3-methoxy-5-methylbenzaldehyde and diamines such aa ethylenediamine, 1, 2-propylenebiamine, 2, 8-dimethyl-2, 3-butylenediamine, 1, 3-propylenediamine and 1, 2-phenylenediamine. The adduction constants of these complexes to dioxygen (O2) were measured in diglyme solution with 4-methylpyridine as an axial ligand. The results showed that their affinity to O2 was influenced remarkably by rigidity of the diamine-Co(Ⅱ) chelating ring in the complexes.
