A benign and facile process for forming monodisperse, hollow porous silica shells of a novel cubic morphology is identified. Templated on monodisperse crystalline germania cores that can be removed via aqueous dissolution, the hollow shells and their core-shell precursors are amenable to assembly into highly porous, gap-free near-monolayer films through manual and evaporative assembly techniques.
