中文摘要： 配位聚合物和多酸由于具有许多奇特的性质，在许多领域里有着实际或潜在的应用，是国内科学家关注的焦点，基于多酸的杂化材料或配位聚合物近年来也有大量的出色研究成果报道，但基于多酸和配位聚合物互为主客体方面的研究却很少。多酸-配位聚合物主客体材料可以通过协同效应或结构的调控而集双方的性能优点。本项目将以一些钼、钨氧簇（六、八核或更高），利用含氧、氮、硫的有机（共轭）配体的协同效应，合成多酸作为主体或配位聚合物作为主体的互为主客体的化合物，进行结构表征和光、电、催化、吸附脱附、离子交换等性能研究，剖析化合物的结构特征、堆积方式、主客体之间的协同和互为模板效应以及有机配体对结构的调控作用及对性能的影响等，总结性能和结构之间的内在联系，并反馈来指导合成工作，最后探索化合物的可能应用。发表论文15~20篇，申请专利1~2项。

英文摘要： Owing to many fantastic properties and the potential applications (or actually have been widely applied in many fields) of the polyoxometalates and coordination polymers, they have been the focuses of many scientists worldwide. There are many interesting reports concerning some hybride materials based on polyoxometalates or the coordination polymers, however, it has been very rarely investigated concerning the host-guest of both polyoxometalates and coordination polymers. Such a host-guest material will merge the merits of both the polyoxometalates and the coordination polymers either by cooperation effects or by structural tuning. Small organic ligands with special structures were prepared first, and the coordination polymers were combined with polyoxometalates to synthesize a series of such host-guest compounds by hydrothermal method through self-assembling. Then the structural determination, properties concerning light, electric, catalysis,adsorption desorption isotherms, ion-exchange Process and so on had been studied,which achieved many meaningful results. Among them, the structure of compound {[Ag2(trz)2][Ag24(trz)18]}[PW12O40]2 shows first that an adamantane-like nanocage can be assembled from simple triazole ligands and does not require a designed, pre-synthesized tridentate ligand, and second that polyhedral nanocages can interlock each other by means of mechanical linkages through all of their vertices to produce multiply catenated infinite extended structures. And the results have been published in Nature Chemistry. Finally,there are 20 SCI papers that had been published and marked as acknowledgements for financial supports from NSFC, and 9 invention patent applications.
