基于分子笼骨架有机多孔材料的制备及其应用研究

Due to their diverse skeletons, light skeleton density, high surface area, high stability and tunable pore, porous organic polymers have received significant attention for applications in gas storage, sensing, light-harvesting and heterogeneous catalysis. Building block is the key parameter for the development of novel porous organic polymers! In contrast to traditional porous organic polymers which constructed from 1-D or 2-D building blocks, we used shape-persistent 3-D cages as novel building blocks for the development of porous organic catalytic and separation materials. The main contents of this project include: Firstly, design and synthesis of organic cages containing functional groups for further polymerization. Secondly, construction of porous organic polymers by using shape-persistent 3-D organic cages as novel building blocks. Finally, the as-synthesized functionalized frameworks will be employed as separators for gas adsorption or as catalysts for organic transformations. Influences of the cage’s cavity size and synthetic methods on structures of materials, and the relationship between structures and properties will also be explored.

有机多孔材料具有组成丰富、骨架密度轻、比表面积高、稳定性强、孔道结构可调等优点，因而被广泛应用于气体存储、传感、有机光电和多相催化等领域。单体是发展新型有机多孔材料的关键！与传统材料使用一维或二维的有机单体不同，本项目拟发展三维有机分子笼为“新单体”，实现新型有机多孔催化、分离材料的有效构建。主要内容包括：1、设计、合成具有可聚合官能团的有机分子笼；2、以有机分子笼为“新单体”，通过聚合反应，合成相应的有机多孔材料；3、研究材料在气体吸附和多相催化反应中的应用，探索分子笼空腔大小和聚合方式与材料结构与性能之间的关系。
