Hybrid Organic−Inorganic Xerogel Access to Meso- and Microporous Silica by Thermal and Chemical Treatment

Hybrid xerogels of general formula (O)1,5Si−C⋮C−(CH2) n −C⋮C−Si(O)1,5 were prepared by sol−gel polycondensation in THF of the corresponding precursors (H3CO)3Si−C⋮C−(CH2) n −C⋮C−Si(OCH3)3, without catalyst. Treatment of the hybrid xerogels was with methanol and water in the presence of 2.0% of ammon...
