Article Abstract
Membrane-based nanofiltration has the potential to revolutionize the large-scale treatment of organic solvents in various applications. However, the widely used commercial membranes suffer from low permeability, narrow structural tunability, and limited chemical resistance. Here, we report a strategy for fabricating covalent organic framework (COF) membranes with solvent-responsive structural flexibility. The interlayer shifting of these COF membranes in polar organic solvents results in sub-nanopores with high selectivity. High rejection rates (>99%), high permeance (>15 kilogram meter hour bar), and excellent organic solvent resistance of these smart COF membranes are achieved for a diverse array of nanofiltration applications.

Decades of antibiotic misuse have spurred an antimicrobial resistance crisis, creating an urgent demand for alternative treatment options. Although phototherapy has therapeutic potential, the efficacy of the most advanced photosensitizers (PS) is essentially limited by aggregation-induced quenching, which significantly reduces their therapeutic effect. To address these challenges, we developed a cationic metallocovalent organic framework (CRuP-COF) via a solvent-mediated dual-reaction synthesis strategy.

In this study, a multifunctional composite membrane (PDMS@CNT@COF@CF) integrating superhydrophobic, efficient photo-thermal conversion, and electrical insulation properties was developed through a functional co-design strategy. The material was constructed by depositing a covalent organic framework (COF) on the surface of carbon nanotube (CNT) via room temperature in situ polymerization. It was then robustly anchored onto a cotton fabric (CF) substrate through polydimethylsiloxane (PDMS) coating.

Global carbon dioxide (CO) emissions caused by the massive utilization of fossil fuels continue to rise, exacerbating the greenhouse effect. Membrane-based CO separation processes are a promising technology for carbon reduction. Covalent organic framework (COF) membranes have shown great potential in the field of gas separation due to their high porosity, tunable pore size, and chemical stability.

Covalent organic framework (COF) holds great potential as next-generation high-performance desalination membrane material owing to their uniform nanochannels (homo-nanochannels) and abundant functional groups, and the hierarchical structures of nanochannels should be rationally designed to break the trade-off between water permeability and ion rejection. Here, a kind of COF membrane with hourglass-shaped nanochannels is fabricated by installing amino-cyclodextrin nanoparticles (CDN) onto the mouth of COF membrane via sequential assembly. The resulting hetero-nanochannels consist of a hydrophilic conical entrance (~1.

The separation of amino acids from complex mixtures remains an essential yet multi-step, energy-intensive process. Membrane separation technology offers a more energy-efficient alternative, but its effectiveness relies on achieving highly precise molecular recognition. Here, we report a homochiral covalent organic framework (COF) membrane with ordered ultra-microporous pore structures for targeted extraction of specific enantiomer from amino acid mixtures.
