摘　　要：合成了以壳聚糖为主体 ,β-萘酚醛为修饰物的不同修饰程度的壳聚糖希夫碱及它们的钴配合物 ,还合成了壳聚糖单体氨基葡萄糖与β-萘酚醛的希夫碱钴配合物。采用 IR、元素分析、XPS、荧光、紫外 -可见吸收光谱法等分析手段对这些化合物进行了表征 ,推测了它们的结构。以邻苯二酚氧化成邻苯二醌为反应模型 ,在完全相同的反应条件下 ,对大分子壳聚糖希夫碱配合物与相应的小分子壳聚糖单体的希夫碱配合物的催化活性进行了比较 。N 2 hydroxy naphthalidenechitosan with different decoration degree, the schiff base of 2 hydroxy naphthaldehyde with D glucosamine, and their cobalt(Ⅱ)complexes were Synthesized. These compounds were characterized by IR,UV VIS,elemental analyses,Fluorescence and XPS respectively. Base on these results, their possible structures were suggested. The catalytic activity of the complexes as an oxidation catalyst was studied. The results showed that the polymer complex is of higher catalytic activity than the corresponding monomeric complex. The isolation effect of polymer may lead to the difference of catalytic activity.
