Abstract
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.
