New linking reactions are highly sought-after in the formation of covalent organic frameworks (COFs), but this is often difficult to achieve since the linkage must be both stable and dynamic. This means that many possible linkage reactions remain unexplored. Instead of forming new linkages <i>de novo</i>, a better approach may be working to convert known linkages into novel ones. We discuss the transformation of imine-linked COFs into amide ones by direct oxidation with retention of crystallinity and permanent porosity. The amide COFs show improved chemical stability relative to their imine-linked progenitors.
