  • When hydronium ions are enriched in confined water, short hydrogen bonds (SHBs) form due to the constrained space of excess protons between pairs of water molecules. Here authors demonstrate a SHB network confined on the surface of ionic COF membranes with tunable -SO3H groups, with proton conductivity of 1389 mS cm-1 at 90 oC.

  • 3D ionic covalent organic frameworks (iCOF) are used in the fabrication of membranes breaking the trade-off between ion conductivity and ion selectivity is challenging. Here, the authors report the fabrication of a 3D sulfonic acid-functionalized iCOF membrane for efficient and selective ion transport, using dual acid-mediated interfacial polymerization

  • Membrane technology holds great promise in separating monovalent cations but the sub-nanometer ion size and the small difference in ion size makes separation of monovalent cations a challenging task. Here, the authors demonstrate the efficient separation of monovalent cations using a COF membrane.
