中文摘要： 多孔有机骨架材料是近年来出现的一种新型的多孔材料，具有低的骨架密度、大的比表面积、良好的物理化学稳定性，在气体吸附、非均相催化、荧光探针、光捕获以及能量存储等方面展现了良好的应用前景。本项目以多孔有机骨架材料为研究对象，拟将具有孔洞和刚性结构的共轭大环有机分子作为砌块，采用多种有机合成方法引入到多孔有机聚合物骨架中，通过调变有机砌块的尺寸、形状和种类，设计合成具有不同孔结构、性质和较高物理化学稳定性的基于共轭大环分子的多孔有机骨架材料，研究其在气体吸附和荧光探针等方面的应用。依据拓扑学原理，充分考虑结构与性能的密切联系，从结构设计入手，通过对共轭大环有机分子和其他有机小分子的合理设计与修饰，发展设计合成基于共轭大环分子的多孔有机骨架材料的新方法和新体系。

英文摘要： Porous organic frameworks have emerged as one novel kind of porous materials in recent years. These materials show promising applications in gas adsorption, heterogeneous catalysis, photoluminescent sensors, light harvesting, photocatalysis and energy storage due to their low framework density, large specific surface area, and good chemical-physical stability. This research project focuses on the design and construction of porous organic frameworks using conjugated macrocyclic compounds with inner cavities and rigid backbones as molecular building blocks through several organic synthetic methodologies. The pore size and nature of porous organic frameworks could be modulated through alternating the size, shape and substitute of organic building blocks. According to the principle of topology and considering the affinity between the structure and properties, we expect to construct a series of new porous organic frameworks with given topology and special functionality by rational design and decoration of conjugated macrocyclic compounds and other small organic building blocks. The resulting porous organic frameworks will be used in gas adsorption and photoluminescent sensors. Our goal is to develop new building blocks, synthetic methodologies and systems for the rational design and synthesis of functional porous organic frameworks.
