4-bis(triallylsilyl)benzene are presented as new precursors for the surfactant-assisted synthesis of ordered mesoporous organosilica with pore walls having crystal-like molecular-scale periodicity. This approach provides a new route to the formation of periodic mesostructures with crystal-like pore walls. The synthesis method presented is applicable to the preparation of mesoporous organosilica with bulky

The synthesis of three-dimensional (Pm3n) cubic phenylene-bridged hybrid mesoporous silica material using a novel allylorganosilane precursor 1,4-bis(triallylsilyl)phenylene and cetyltrimethylammoniumchloride (C16TMACl) as a structure-directing agent in acidic medium is presented. Sulfonic acid functionalized derivatives of these materials are effective in Friedel–Crafts acylation reactions and in controlling the atmosphere emission of volatile organic compounds, which are responsible for ground level ozone, air toxicity and smog.
