Although most Covalent Organic Frameworks (COFs) are traditionally synthesized via solvothermal methods that produce bulk COF powders, development of colloidal COF syntheses has deepened our mechanistic understanding of COF formation leading to higher materials quality. Here, we study the crystallinity and materials quality of colloidal imine-linked COFs synthesized with different carboxylic acid catalysts. In addition to affecting crystallinity, catalyst acidity affects COF particle size and morphology.
