Thin films with accessible regular nanometer‐sized pores… are highly sought for they may open up new opportunities for fabrication of nanomaterials. Y.‐U. Kwon and co‐workers developed a method to form thin films composed of titania species and surfactant molecules into a cubic self‐assembly structure with body‐centered cage‐like pores and with one of the body diagonals oriented perpendicular to the substrate. Calcination makes the film shrink vertically, by which the pores fuse into vertical channels. The ordered vertical nanochannels can be exploited for fabricating arrays of nanomaterials.
