Green and Large‐Scale Synthesis of Covalent Organic Frameworks for Practical Applications

Abstract Covalent organic frameworks (COFs) are emerged as a class of crystalline porous organic materials and attracted lots of interest. Nevertheless, the harsh synthetic condition greatly limits the large‐scale preparation and industrial application of COFs. Faced with actual industrial demands, the green and large‐scale synthesis of COFs becomes an extremely important research field. Many researchers have gradually shifted from building new COFs in the laboratory to their large‐scale preparation. It opens up an available pathway and provides a platform for practical applications of COFs. Excitingly, various green synthesis strategies are developed to construct COFs in large quantities in recent years. This review focuses on recent developments in the green and large‐scale preparation of COFs and their practical applications. Moreover, some typical examples are discussed to highlight the advantages and disadvantages of different synthetic methodologies. Finally, prospect and challenge are proposed to develop green and large‐scale synthesis of COFs for practical applications.
