Self‐standing films of surfactant mesostructured materials have been prepared with vinyltrimethoxysilane (VTMOS) as a silica source. The transparent films, obtained by the co‐condensation of VTMOS and tetramethoxysilane, can easily be converted to porous silica films by calcination. The authors reveal the porous structure of these materials by X‐ray diffraction and transmission electron microscopy investigations. Application of the self‐standing films and the porous materials is envisaged in the fields of catalyst supports, separation, and hosts for bulky organic species.
