异金属簇-有机骨架的组装策略与性能开发

Transition-metal-cluster-organic frameworks, the new-type porous materials with regular channel structures and unique physiochemical properties, have attracted considerable interests by both chemists and materials scientists in recent years. On the other hand, polyoxometalates, a class of inorganic materials with stable high-nuclear metal-oxo core configurations and enormous structural diversity, have wide applications in areas of catalysis, biomedicine and magnetism. This research project will focus on the interdiscipline of the above two research systems. The major subjects include: (1) To explore feasible synthetical strategies for combining fascinating transition-metal clusters and polyoxometalate clusters to construct novel composite materials of heterometallic cluster-organic frameworks; (2) To investigate the physiochemical properties of new composite materials and their potential applications in guest-host chemistry, gas adsorption and separation and organic catalysis; (3) To realize the modulation of the physiochemical properties of new materials by utilizing different functional ligands and different metal-cluster secondary building units. And then to further study the relationship between structures and properties of the new materials with attempt to improve properties of new materials. This project will not only expand the research areas of the related research systems, but also provide experimental and theoretical support for developing novel porous materials.

过渡金属簇-有机骨架是一类具有规则孔道结构和独特物理化学性能的新型多孔材料，近年来引起了化学家和材料学家们的广泛兴趣。多酸是一类构型丰富、具有稳定的高核氧簇结构特点的无机化合物，在催化、生物医药、磁性等功能材料等领域得到的广泛的应用。本项目拟在上述两个体系的前沿交叉领域开展创新性研究工作。主要内容包括：(1) 采用目前已经研究比较成熟的过渡金属簇与多酸簇这两种属性不同的金属簇共同作为次级构筑单元，探索可行的合成策略来设计和构建新颖的异金属簇-有机骨架材料; (2)研究所获得的新材料的物理化学性质以及在主客体化学、气体吸附分离和有机催化等方面的潜在应用; (3) 通过有机配体的功能团控制、不同的金属簇构筑单元的组合来调控新材料的物理化学性能，研究新材料的构效关系，优化新材料的相关性能。本项目研究内容将为相关研究体系开拓新的研究空间，为新型多孔材料的开发提供实验与理论依据。
