Mesoporous films with almost “single‐crystalline” arrangements of spherical pores are obtained by “evaporation‐ induced self‐assembly”: the films are dip‐coated onto a sublayer with sufficiently different surface tension and nanometer‐scale periodicity. A film with almost single‐crystalline (biaxially oriented) pore structure nucleating on an appropriately mesostructured sublayer is shown in the figure and on the cover.
