中文摘要： 具有分子筛拓扑结构的微孔金属－有机框架材料研究是当前研究热点之一，但是基于金属簇单元构筑的类分子筛框架化合物却鲜有报道。前期我们成功实现了以四面体Cu4I4簇单元构筑具有分子筛型MTN结构的簇有机框架材料，在此基础上，本项目拟进一步发展具有分子筛拓扑结构的中性和阴离子型簇有机框架材料；通过选用中性含氮桥连配体或阴离子型咪唑配体等与中性Cu4I4簇单元设计组装去实现该目标；将重点探索金属簇，有机配体和分子模板等在组装过程中的相关结构基础问题，理解该类材料在结构构筑过程中的关键因素，通过改善和优化合成反应条件，设计合成性能稳定且适用于气体吸附/分离并具有荧光性能的新型类分子筛材料。

英文摘要： In current research, one hot topic is to synthesis microporous metal-organic frameworks with zeotype topologies. However, such zeotype frameworks are often built from single metal centers linked by bridging ligands. The cluster-based zeolitic frameworks are rarely known to date. In our former research, we first designed an unusual zeolitic cluster organic framework based on tetrahedral Cu4I4 clusters, which showed zeotype MTN topology. The main purpose of this project is to further develop a series of such zeolitic cluster organic frameworks. Here, we plan to use neutral or negative N-donor bridging ligands, such as hexamine or imidazolate, to link neutral tetrahedral Cu4I4 clusters into zeotype frameworks. To fabricate this aim, many synthetic conditions including solvents, temperature and templates will be carefully considered. Such research will tell us some valuable assembly principles, and several types of zeolitic cluster organic frameworks with interesting gas sorption/separation or luminescent properties will be successfully synthesized.
