Direct Access to Bicontinuous Skeletal Inorganic Plumber's Nightmare Networks from Block Copolymers

Pipe‐dream realized: The as‐made nanocomposite derived from a block‐copolymer‐directed sol–gel synthesis consists of silica networks embedded in an organic matrix. Calcination of the structure at high temperatures gives a final skeletal silica network consistent with the morphology called plumber's nightmare (point group Im$\bar 3$m; see small‐angle X‐ray scattering (SAXS) pattern of an inverse form of this morphology).
