| COFs（Covalent Organic Frameworks）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有应用前景。有机硼酸中的硼元素最外层空的p轨道与π键产生特殊的轨道相互作用，也可与路易斯碱发生配位作用，上述特点使其能够被设计为结构和功能导向的构筑基元。有机硼酸酯的形成由于在结构中引入了可以参与共轭体系的硼原子，进而带来新颖的性质。本文从合成、性质以及结构等方面介绍了由有机硼酸（boronic acid）构筑的结构和功能导向COFs及其发展趋势。 |

我帮你翻译了一下，是个外行，呵呵，你看这样行吗？ Covalent Organic Frameworks (COFs) are a kind of porous crystal materials with clear pore size distribution, which have an application prospect in gas storage, catalysis, separation, optical devices and chemical sensing etc. The outermost empty p orbital of the boron element of organic boric acid can has a special orbit interaction with the π-bond, and it can also has a coordination interaction with the Lewis base. So it can be designed as the building block of structure-oriented and function-oriented materials according to these properties. The formation of organic boric acid ester will perform novel properties because the boron atom is introduced to participate into the conjugate system of the structure of material. In this paper, the synthesis, properties and structure of boronic acid are introduced, and the function-oriented COFs as well as its development trends is also introduced. |
