Front Cover : In article number 2100115 by Takahiro Ichikawa, Xiangbing Zeng, and co‐workers, gyroid‐nanostructured polymer films, having multi‐layered H 2 gas barriers and a 3D continuous proton conduction pathway, are created from specially‐designed bicontinuous cubic liquidcrystalline monomers. They show high proton conductivity of the order of 10 −1 S cm −1 and extremely low H 2 gas permeability of the order of 10 −15 mol m m −2 s −1 Pa −1 .
