共价键有机框架(Covalent Organic Frameworks,COFs)是具有明确孔径分布的多孔晶体材料,在气体贮藏、催化、分离、光学器件和化学传感等方面均有应用前景。有机硼酸中硼原子最外层空的p轨道能与π键产生特殊的轨道作用,也可与路易斯碱发生配位作用。上述特点使其能够作为结构和功能导向的基元而用于构筑共价键有机框架。本文从合成、结构以及性质等方面对有机硼酸构筑的共价键有机框架进行了介绍。
Covalent Organic Frameworks (COFs) are porous crystalline materials with well-defined pore size distribution and have potential application in gas storage, catalysis, separation, optics and chemical sensing. Organic boron atoms in the outermost outermost boron p-orbitals can produce a special orbit role, but also with the Lewis base coordination role. These features make it possible to construct a covalent organic framework as a structural and function-oriented motif. In this paper, the organic framework of organoboronic acid constructed from the aspects of synthesis, structure and properties is introduced.
