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. Our group has contributed significantly refining these balance enhancing the performance resulting COFs.In addition binding patterns, we also developed strategies control micro- macromorphologies COFs, which is crucial optimizing properties For example, explored hierarchical using templating techniques forming composites other materials. These enable us fine-tune porosity thereby improving applications like catalysis. Hierarchical structures enhance photocatalytic efficiency providing larger area light absorption facilitating transport photogenerated charge carriers.We further examine practical primary focus photocatalysis. Photocatalysis uses accelerate ideal this purpose band gaps large areas. research shown versatile photocatalysts effectively catalyze reactions water splitting, carbon dioxide reduction, hydrogen peroxide cross-coupling By exploiting achieved significant improvement many reactions.With comprehensive overview, aim contribute development understanding encourage innovation promising field.

The diversity of covalent organic frameworks (COFs) is continuously expanding, providing various materials with tailor-made structures and properties. However, the development crystalline three-dimensional (3D) COFs new topologies an essential but arduous challenge. In this study, we first developed one kind 3D lil topological structure, which were assembled by D4h- C2h-symmetric building blocks. determined in a space group Imma, each D4h-symmetric unit connected four units, forming noninterpenetrated network. densely packed copper phthalocyanine stable polyimide linkage render these as polymeric material high dielectric constant low loss at frequencies (>1 kHz). Significantly, was 63, constitutes record value among phthalocyanine-based polymers. Therefore, study not only provides important guidance for design lil-net also supplies promising application high-energy-density pulsed capacitors.
