基于有机硼酸的共价键有机框架研究进展

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。

Progress on the Covalent Organic Frameworks Based on Organic Boronic Acid

Covalent Organic Frameworks(COFs) are a class of porous crystal materials with clear pore size distribution,which have application prospects in gas storage,catalysis,separation,optical devices and chemical sensing,etc.The outermost empty p orbit of boron atom in boronic acid can have a special orbital interaction with the π-bond,and it can also have coordination interaction with the Lewis base.So it can be designed as the building block of structure-and function-oriented materials with specific properties.In this review,the synthesis,structure and properties of COFs based on boronic acid are introduced.
