Chiral bis‐alkoxysilanes are used as building blocks for the synthesis of new periodically ordered mesoporous organosilica materials (see figure). A bis‐alkoxysilane molecule with a chiral group as a bridging organic ligand is prepared via enantioselective organometallic catalysis using a ruthenium catalyst with 2,2′‐bis(diphenylphosphino)‐1,1′‐binaphthalene as a ligand. The synergistic co‐assembly is then used to prepare a high‐surface‐area mesoporous material with an average pore size of about 3 nm.
