中文摘要： 孔性金属-有机框架材料由于具有良好的可设计性和高的比表面积，在异相催化领域已展现出诱人的前景，但框架材料中催化活性位点的构建是一个巨大的挑战。基于原子簇化合物丰富的活性位点及特殊的能带结构，拟开展Mo(W)-S-Cu原子簇-有机框架材料的合成及异相催化性能研究。采用低温固相法合成不同骨架结构的Mo(W)-S-Cu原子簇单体；以此为次级构筑单元，与不同尺寸的酰胺键修饰的高对称性吡啶配体配位，构筑微孔兼具催化活性的原子簇-有机框架材料。系统考查该类框架材料的骨架结构及孔道环境；深入研究此类材料在微孔环境下对若干有机反应的催化性能和催化机理；揭示原子簇骨架类型、孔道环境和催化性能间的构-效关系，开发出性能优良的Mo(W)-S-Cu原子簇-有机框架催化材料。本项目的实施，可为此类框架材料在异相催化中的研究和应用提供科学依据和理论基础；同时对原子簇和金属-有机框架研究领域的交叉融合具有重要意义。

英文摘要： Porous metal-organic framework with good designability and high surface area have been demonstrated as an excellent catalyst in heterogeneous catalysis. How to build the catalytic active sites has been a huge challenge. Due to the rich active sites and special band structures of cluster compound, this project plans to carry out research work on the preparation and heterogeneous catalysis of Mo(W)-S-Cu cluster-organic framework materials. Low-temperature solid-phase method will be adopted to synthesize Mo(W)-S-Cu cluster monomers with various skeleton structures. Based on the coordination interaction of cluster monomers and highly symmetric multidentate pyridine ligands with bridging acylamide groups, microporous cluster metal-organic framework materials with high catalytic activity will be prepared. The skeleton structures, channel enviroments, organic catalytic properties and mechanisms will be systematic explored. The structure-activity relationships between the skeleton type, channel envirioment and catalytic activity will be revealed. The ultimate aim is to obtain some Mo(W)-S-Cu cluster-organic framework materials with high catalytic property. The project can provide scientific basis and theoretical foundation for the heterogeneous catalysis. In addition, it also have important academic signifinace for the
