Abstract
AbstractNanoporous materials were prepared by using silsesquioxane containing three alkoxy groups and a non‐hydrolysable organic moiety. The influences of pH and precursor ratios of silsesquioxane and tetraethyl orthosilicate (TEOS) on the preparation of organo‐modified periodic mesoporous materials were investigated. These materials were characterized using small angle X‐ray scattering, infrared spectroscopy and thermogravimetric analysis. A non‐ionic triblock copolymer was used as a structure‐directing agent to provide large pores with a high density of silanol groups. It was found that silsesquioxanes could form ordered nanoporous materials in the presence of TEOS by controlling the pH and the co‐precursors ratio, despite their structural irregularity.© 2002 Society of Chemical Industry
