This paper describes the first demonstration of a general concept for achieving facile proton conduction within a class of layered two-dimensional aza-fused π-conjugated covalent organic frameworks (COFs). The built-in phenanthroline moieties promote efficient adsorption of water and acidification by H3PO4 to produce excellent proton conductivities of 10–5 and 10–3 S/cm for the pristine and acidified analogues, respectively. These molecular design concepts are poised for development of highly stable proton-conducting materials.
