ConspectusCovalent organic frameworks (COFs) are a rapidly emerging class of crystalline porous polymers, characterized by their highly defined, predictable, and tunable structure, porosity, properties. COFs can form both two-dimensional (2D) three-dimensional (3D) architectures, each with unique characteristics potential applications. 2D have attracted particular interest due to favorable structural optoelectronic They be equipped range different functional moieties in backbone, ranging from acidic basic, hydrophilic hydrophobic, metal-coordinating redox-active functions. In addition, crystallinity, high specific surface area, remarkable thermal chemical stability make them attractive for variety applications, including gas separation, catalysis, energy storage, optoelectronics.This Account provides detailed overview our recent efforts synthesize apply COFs. First, various synthesis routes discussed, focusing on methods that involve reversible irreversible linkage reactions. Reversible reactions, such as imine or boronate ester formation, advantageous producing because they allow error correction during synthesis. contrast, carbon–carbon carbon–nitrogen bond yield greater stability, although controlling crystallinity more challenging.
