【摘要】：有机多孔聚合物(organic porous polymers,OPPs)材料是一类由强共价键将不同几何构型的有机分子砌块链接而成的多维度的多孔网络骨架材料,近年来成为多孔材料发展的一个新方向.按其结构的有序程度划分,OPPs包括无定型(如CMPs,HCPs,PIMs,PAFs等)和晶态(如COFs,CTFs)多孔聚合物两大类.因具有质轻、较大的比表面积、优异的多孔特性、稳定性好、结构与功能可预先设计和精确调控等优点,OPPs在气体存储/分离,非均相催化,光电转换,化学/生物传感,能量存储与转换等诸多领域有着广泛的应用前景.基于"自下而上"的构筑策略,以一种或多种具有特定功能的有机共轭分子为构筑单元,通过其分子间的自聚或共聚来实现二维、三维共轭高分子网络的可控构筑,发展了一系列具有优异光电、催化性能的功能性有机骨架材料.本文总结了近年来作者所在课题组报道的以功能性共轭有机分子为反应单元,自下而上构筑共轭多孔聚合物材料的战略和方法,主要探索了其结构特征以及在光电转换和非均相催化领域等的初步应用.
[Abstract]:Organic porous porous polymers (OPPs) are a kind of multi-dimensional porous network skeleton materials which are made up of organic molecular blocks with different geometric configurations by strong covalent bonds. It has become a new direction in the development of porous materials in recent years.According to the order of its structure, OPPs can be divided into two categories: amorphous (such as CMP sn HCPsPIMsPIMsPPAFs) and crystalline (such as COFsCT-Fs) porous polymers.Because of its advantages of light weight, large specific surface area, excellent porous properties, good stability, structure and function can be designed in advance and accurately regulated, OPPs can be used in gas storage / separation, heterogeneous catalysis, photoelectric conversion, chemical / biological sensing, etc.Energy storage and conversion are widely used in many fields.Based on the "bottom-up" construction strategy, one or more organic conjugated molecules with specific functions are used as building units to realize the controllable construction of two-dimensional and three-dimensional conjugated polymer networks by self-polymerization or copolymerization of their molecules.A series of functional organic skeleton materials with excellent photovoltaic and catalytic properties have been developed.In this paper, the strategies and methods of constructing conjugated porous polymer materials from bottom to top with functional conjugated organic molecules as reaction units reported by the authors in recent years are summarized.Its structural characteristics and preliminary applications in photovoltaic conversion and heterogeneous catalysis are explored.
