Keeping order : Mesoporous crystalline iron oxide thin films were prepared by using special block copolymer templates. The optimized templating properties and temperature stability of the porogens allowed a crystal‐to‐crystal phase transition (from goethite to hematite) within the walls of the porous scaffold without disruption of the mesostructure.
