Vinylene-linked covalent organic frameworks (COFs) have attracted significant attention for their exceptional chemical stability and optoelectronic properties. However, the large-scale synthesis of vinylene-linked COFs remains challenging, as base- or acid-mediated solvothermal methods often result in uncontrolled crys...
Covalent organic frameworks (COFs) unlock opportunities to unite rapid mass transport with molecular-level sieving through membranes. However, achieving long-range crystallographic order within these membranes remains a central challenge that limits their separation precision. Here, we report a monomer-driven strategy...
The synthesis of highly crystalline covalent organic frameworks (COFs) has recently been achieved, but strategies to obtain monodispersed single crystals of uniform size and shape remain elusive. Here, we show that simply adding silica nanoparticles (SiNPs) to a conventional solvothermal synthesis directs imine-based...
Covalent organic framework (COF) nanosheets are ideal building blocks for fabricating high-performance membranes. The production of COF nanosheets in water is a significant step towards sustainable synthesis but remains an unresolved challenge. Herein, we report an aqueous synthesis method for COF nanosheets via a gr...
Poly(ionic liquid)-grafted UiO-66-NH2 gels are developed as a high-performance and co-catalyst-free platform for efficient CO2 capture and chemical fixation under mild conditions. To address the mass transfer limitations and high energy barriers typical of purely microporous powder materials, a series of hierarchically...
Over the past decade, postsynthetic linker exchange (PLE) has emerged as a promising strategy for fabricating high-quality covalent organic frameworks (COFs), leveraging the principles of dynamic covalent chemistry (DCC). However, the synthetic challenges posed by the complex parent entities used in PLE, such as COFs a...
