Covalent organic framework (COF) membranes hold potential for widespread applicability, but scalable fabrication is challenging. Here, we demonstrate the disorder‐to‐order transformation from amorphous polymeric membrane to crystalline COF membrane via monomer exchange. Solution processing is used t...
