The synthesis of mechanically stable mesoporous silicas with large pores can be achieved by casting the lyotropic phases of amphiphilic block copolymers. Here is presented new non‐ionic polymer templates that allow larger pore diameters than previously reported with this procedure. In the Figure is depicted a silica with 63 nm diameter cylindrical pores.
