中文摘要： 新型多孔择形催化剂的合成及其催化性能研究是无机化学和催化交叉研究的热点内容。本项目针对傅-克烷基化催化反应中传统催化剂选择性低、结构不易调控的问题，以新型微孔金属-有机膦酸材料为研究对象，在已有相关工作基础上，以GIS、MER和RTL型微孔结构为目标，采用配体预功能化方法和原位金属掺杂方法，研究上述微孔材料的合成、改性和孔径调节的方法以及它们的傅-克烷基化择形催化性能，分析它们的结构类型、改性方法、孔径大小与催化效率、选择性之间的关系，确立微孔金属-有机膦酸材料在择形催化方面的特点和优势。本项目预期将揭示这类微孔材料的合成条件与结构、催化性能之间的关系，建立结构类型、改性方法与傅-克烷基化择形催化之间的联系。项目研究成果不仅对微孔金属-有机膦酸材料的合成、改性研究具有重要的意义，而且能够为择形催化性能导向的新型微孔材料设计合成提供科学依据。

英文摘要： Design and synthesis of novel porous materials for shape-selective catalysis have drawn considerable interests in both fields of inorganic and catalytic chemistry. Previous studies point out that traditional Friedel-Crafts alkylation catalysts have poor selectivity to the products and/or their structures are less adjustable, which makes researchers turn more attention to the novel porous materials. Based on our previous research work, we choose the microporous metal-organophosphonate as the research object in this proposal. The novel metal-organophosphonates with three different types of topologies, which are GIS, MER and RTL, will be synthesized firstly. Then their functionalized microporous materials will be isolated via ligand pre-functionalization and/or in-situ metal doping strategies. Finally, in order to understand the relationships of their structures, functionalization methods, pore sizes with their catalytic ability and selectivity, the Friedel-Crafts alklation reactions will be extensively investigated by using these obtained metal-organophosphonates as catalysts. This research proposal is expected to reveal the functioanlization methods of metal-organophosphonates and the relationship between the synthesis conditions, structures and their catalytic properties. Therefore, the research results will ben
