The present invention relates to a method for preparing a covalent organic framework (COF) materials - a reversible polycondensation/termination method, the COF materials prepared by the method have high crystallinity, high specific surface area, regular and controllable morphology. The present invention also relates to a method for repairing defects of COF materials - reversible degradation-recombination, the method can eliminate defects of existing COF materials, thereby increasing the crystallinity and specific surface area of COF materials and improving their morphological characteristics.
本发明涉及一种共价有机框架(COF)材料的制备方法--可逆缩聚/终止法,该方法制备的COF材料具有高结晶度、高比表面积、形态规整且可控。本发明还涉及一种修复 COF 材料缺陷的方法--可逆降解-
重组法,该方法可以消除现有 COF 材料的缺陷,从而提高 COF 材料的结晶度和比表面积,改善其形态特征。
