We report the preparation of a new class microporous materials, aryl-bridged polysilsesquioxanes, through the sol-gel processing of bis(triethoxysilyl)aryl and bis(trichlorosilyl)aryl monomers. These materials incorporate aryl groups in silsesquioxane networks with hexacoordinate connectivity. It is shown that organic spacers can be inserted at regular intervals into the Si-O-Si silicate structure. Sol-gel processing allows for the preparation of aryl-bridged polysilsesquioxanes, high surface area materials that have certain morphological properties in common with both silicates and simple poly(arylsilsesquioxanes), but with added opportunities for systematic modification.
