%X an innovative series of silica-based hybrid materials containing pendant cationic ammoniumpropyl groups was obtained using the sol-gel method, by varying the molar ratio of the inorganic and organic precursors. thermogravimetric analysis showed that samples were thermally stable up to 260 oc. results obtained by x-ray diffractometry, transmission electron microscopy, 29si nuclear magnetic resonance and elemental analysis were compatible with a silsesquioxane layered structural model showing basal distances up to 5.4 nm, containing amorphous silica in the interlayer space.
