Covalent organic frameworks (COFs) are less stable as catalysts than previously thought but remain highly active. COFs are promising designer catalysts, for example for the sustainable production of chemicals and fuels. Their properties can be adjusted very specifically to catalyze a desired reaction based on their precise tunability, both in terms of molecular structure and chemical compositions.
