Well stacked : Organic crystals of small molecules constitute an alternative to common polymeric electrolytes (Nafion 117) and inorganic crystals that are employed as proton exchange membranes in fuel cell systems. A phosphonic acid containing hexaphenylbenzene forms a columnar supramolecular array and exhibits a high and constant intrinsic conductivity of 3.2×10 −3 S cm −1 from 120 to 180 °C under 1 bar H 2 O atmosphere (see picture).
