中文摘要： 共价有机框架（COFs）由于其固有的刚性、优良的热稳定性、较低的分子密度、高度有序的二（三）维精确拓扑结构以及在气体贮藏、光、电器件、能源和环境等领域所表现出了优异的应用前景，而受到材料学家和化学家的广泛关注和研究。目的性的引入功能化的分子砌块，可以使最终的COFs材料具有多样的功能性质。本课题选择结构稳定、功能多样性的卟啉作为骨架分子，拟开展基于卟啉骨架分子的共价有机框架功能材料的设计、制备及其相关功能性质的研究；通过在卟啉的周边链接多种功能基团、在卟啉的中心引入不同的金属以及采用各种合成方法来获得高级二（三）维有序的COFs功能材料；对卟啉周边取代基的种类和位置以及中心金属的种类- - -配合物的结构和性质- - -高级有序COFs材料的结构- - -COFs功能材料的相关性质之间的构效关系进行探索研究，系统地研究总结各个环节之间的一些共性规律，探索设计、制备更高性能COFs材料的新思路和新方法。

英文摘要： Base on the inherent rigidity, excellent thermal stability, low molecular density and a highly ordered two ( three ) dimensional topology in comparison with the excellent applied prospects in the gas storage, optical, electrical devices, energy and environment, etc., covalent organic frameworks (COFs) have attracted widespread attention and research of materials scientists and chemists. Introduction of functional building blocks will endow the final COFs materials with variously functional properties. In our project, porphyrins are selected as the building blocks to construct the COFs due to their remarkable structural robustness and various functional properties. We will carry out the design, synthesis and application research of COFs based porphyrins. By linking a variety of functional groups at the periphery of porphyrin, introducing different metals in the center of the porphyrin, and adopting various synthetic methods, well-defined, (two) three-dimensionally ordered COFs nanoporous materials would be obtained. We will investigate the structure-activity relationship among sorts and location of peripheral substituents and metal ions, the structure and properties of porphyrin, the structure of well-defined, (two) three-dimensionally ordered COFs nanoporous materials, and the functional porperties of COFs materials. After systematically summarizing the common principle of each aspect, we will provide theoretical guidance for the design of novel, high performance COFs functional materials.
