Periodic mesoporous organosilica has synthesized by supramolecular templating method, which material contains both organic and inorganic parts. Two parts are covalently bonded and homogeneously dispersed at the molecular level in the framework. They are highly ordered at the mesoscale. TEM images of PMO show well ordered hexagonal pores and uniform size. BET nitrogen adsorption measurements show high surface area and narrow pore diameter. The synthetic procedure to polymerize the organosilane monomer containing two triethoxysilyl groups in the presence of surfactant can be applied to the synthesis of a variety of highly ordered organic-inorganic hybrid mesoporous materials.
