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
