Novel Catalysis Systems for the Synthesis of Covalent Organic Frameworks

Abstract Covalent organic frameworks (COFs), an emerging class of crystalline polymers, are meticulously constructed through covalent bonds, resulting in well‐defined structures and crystalline characteristics. Precise control over their architecture, permeability, and functionality can be easily achieved simply via selection of precursor monomers. The tailored architecture and functionality make COFs versatile for various applications including gas storage, pollutant removal, catalysis, and energy storage. Efficient synthesis of COFs with high crystallinity and high yield significantly improves their performance. However, conventional synthetic methods often involve complex setups and costs. Innovations in catalysis have emerged as solutions, including refined activation procedures, novel catalysts, and alternative synthesis conditions. This review comprehensively explores current catalysis systems for COF synthesis, detailing catalysts for various linkages, elucidating mechanisms, and addressing challenges. Future directions and extensions of COF synthesis and applications are also highlighted.
