Materials built from metal centres and organic ligands have traditionally attracted attention for their channels’ host–guest properties. Now, controlling the occupancy of the channels by guest molecules has resulted in a framework that conducts protons under anhydrous conditions and acts as a gas-tight membrane, offering a promising approach to fuel-cell electrolytes.
