多酸无机配位聚合物的合成和性质研究

Abstract: A number of reaches have been proceeded on the inorganic polyoxometalate coordination polymers which using polyoxometalate as multi ligands. 5 of novel products with different structure have been obtained. Of which [Mo3O9(2,2-bpy)2]n is constituted by the helix through the covalent bond, the other 3 of [Cu(o-phen)2Mo4O13], [SMo12O40][H24,4-bpy][4,4-bpy] [4,4-bpy] and [Cu2(o-phen)2O2] crystals possess particular structures and the mixed oxides of Mo2.5Cu3O9 showes high conductivity and catalylytic activity. We also studied several thermocatalytic and photocatalytic reactions using polyoxometalates as catalysts.

本项目提出的“多酸无机配位聚合物”是一类以多酸阴离子为多齿配体与金属离子中心桥联配位形成的线状，层状高分子化合物。通过配为聚合的方式引入稀土和过渡元素金属是一种新的修饰多酸的光电磁和催化性质的合理途径，扩大了多酸化学的研究范围，为同多酸研究开拓了空间，有望开发一批具有优越性能的材料。
