Porous organic frameworks (POFs) are novel porous materials that have attracted much attention due to their extraordinary properties, such as high specific surface area, tunable pore size, stability and ease of functionalisation. However, conventional synthesised POFs mostly large-sized particles or insoluble powders, which difficult recycle low mass transfer efficiencies, limiting the development cutting-edge applications. Therefore, processing POF into membrane structures is great significance. In recent years, interface engineering strategies proved be efficient methods for formation membranes. this perspective, advances in use interfaces prepare membranes reviewed. The challenges strategy potential applications formed discussed.

Abstract Crystalline porous organic polymers (CPPs) or covalent frameworks (COFs), are composed by light elements linked bonds. Despite the remarkable progress attained, there still bottlenecks limiting further development, some of them related to presence defects during their synthesis as well in‐depth understanding structure active centers and/or details reaction mechanism. Indeed, very often proposed structures far from reality because and disorders have not been considered. The present review provides an illustrative overview “defects disorder in COFs”. These include those only generated manipulation COFs, but also lack crystallinity, stacking network vacancies. starts giving general remarks on COFs synthetic methods, followed different methods play manage defects, how minimize take advantage gain new properties applications. Selected characterization techniques quantify defective sites presented. Finally, challenges future opportunities field summarized last section.

Covalent organic frameworks (COFs) have been remarkably evolved within the field of photocatalysis owing to their customizability and targeted functionalization. However, exciton effect arising from Coulomb interaction among electrons–holes cannot be disregarded. Exploring new approaches regulate dissociation on COFs facilitate is significant. Within this work, localized defects were fabricated skeleton by one-step synthesis method introducing monoaldehyde electron donors (pyrene, ferrocene, triphenylamine). The formation D–A configuration can directionally change local electronic structure charge distribution induce enhanced dipole polarization, thus, promoting enhancing photocatalytic activity. Among them, pyrene donor-constructed defective COF exhibited a 7.8-fold increase in aqueous-phase oxygen-containing photopolymerization rate relative pristine COF, with conversion 80% 30 min.

Abstract Covalent organic frameworks (COFs) have garnered significant attention for nearly two decades due to their exceptional structural designs, tunable properties, and wide‐ranging applications. Recently, a novel subclass of COFs known as partially condensed, sub‐stoichiometric (ss‐COFs) has emerged. This presents promising new avenue constructing distinct COF structures in contrast fully stoichiometric (fc‐COFs). ss‐COFs are deliberately designed with periodic unreacted functional groups, thereby giving rise intriguing electronic, optical, catalytic properties. The deviation from conventional approach opens up prospects tailor material properties unexplored Here, this review focuses on the latest advancements breakthroughs ss‐COFs, including topological design, structure characterization, synthetic method, practical From basic designing principles cutting‐edge it will be explored how paving way research pushing boundaries toward scientific technological possibilities.
