Covalent organic frameworks (COFs) linked by imine bonds have attracted significant attention, primarily due to the accessibility of monomers and facile synthesis highly crystalline materials. However, reversible nature raises stability concerns for these materials in practical applications. Therefore, there is a pressing need development imine-linked COFs that can combine high crystallinity, good stability, functionality.
