由硼酸结构单元和 2,3,6,7,10,11-六羟基苯并菲合成了三种新的结晶微孔和介孔二维共价有机骨架，称为 COF-6、-8 和 -10，并进行了结构表征。这些由 C2O2B 环构成的材料形成重叠层状结构，孔径范围为 6.4 至 34.1 埃，并且被发现具有高热稳定性、低密度和高孔隙率，如 COF-6、-8 和 -10 的表面积分别为 980、1400 和 2080 m(2) g(-1) 所示。孔径和结构的控制证明了网状化学方法对材料设计的有效性。
Three new crystalline microporous and mesoporous 2D covalent organic frameworks termed COF-6, -8, and -10 from boronic acid building blocks and 2,3,6,7,10,11-hexahydroxytriphenylene have been synthesized and structurally characterized. These materials constructed Of C2O2B rings form eclipsed layered structures with pore sizes ranging from 6.4 to 34.1 angstrom and are found to have high thermal stability, low density, and high porosity as indicated by the surface areas of 980, 1400, and 2080 m(2) g(-1) for COF-6, -8, and -10, respectively. The control of pore size and structure demonstrates the effectiveness of reticular chemistry methods toward materials design.
