中文摘要: 应用结构设计的观点,选用高配位数稀土金属元素为中心的多面体作结构基元,通过其与刚性有机配体相作用构筑稀土金属-有机配位多孔材料。研究稀土金属与有机配体间的相互作用机制,总结不同结构稀土金属中心多面体结构基元、及多孔结构构筑规律。同时通过有机与无机配体的协调、有机配体及孔道的可控修饰进行材料的功能设计。实现具有特殊结构与性能的稀土金属-有机配位多孔材料的设计合成。合成的稀土金属-有机配位多孔材料兼有孔道结构特点和稀土金属、有机组元的物化特性,可能在吸附、发光、气体贮存、分子识别等方面的获得应用。

英文摘要: Based on the structure design, rare-earth metal element centered polyhedra with high coordination number will be used as the basic building block, which will be combined with organic ligands to contribute the rare-earth metal-organic coordination porous materials. This work will investigate the interaction mechanism between the metal and organic ligands,and further obtain the rules for the contribution of polyhedra and porous structures. On the other hand, through the corresponding of inorganic and organic ligands, and the controlled modification of organic ligands and pores, the founctionalization of the materials might be realized.The synthesized rare-earth metalorganic coordination porous materials might possess the physicochemical features of porous structures, rare-earth metal, and organic species, and have the potential in the areas of adsorption, luminesence, gas storage, and molecule identification.
