No holes barred : Trimethylene‐bridged 1 can be prepared from [{SiCH 2 (OEt) 2 } 3 ]. Compound 1 can be directed to self‐assemble by a tri‐block copolymer template to form a periodic mesoporous organosilica with highly ordered and uniform‐diameter mesopores in which practically all the building blocks remain intact within the as‐synthesized and template‐extracted material.
