摘要：

High-quality phenyl-bridged organosilicas (p6mm) were prepared under acidic conditions using nonionic alkyl poly(oxyethylene) oligomers as structure-directing agents. In addition to the long-range order of the pore system, these materials exhibited a novel molecular order of the phenylene rings within the pore walls different from that observed in samples prepared under basic conditions in the presence of alkyltrimethylammonium surfactants.
