XRD, N(2) sorption isotherm and TEM analysis revealed that the mesoporous structural ordering is retained after the functionalization of organic groups while solid-state NMR techniques like (13)C CP MAS NMR and (29)Si MAS NMR show the presence of sulfonic acid groups and the stability of the mesoporous framework with integrated ethane moieties as bridging groups. The hybrid material was more active, selective and stable than the conventional sulfonic acid containing mesoporous catalysts in the Claisen-Schmidt condensation of acetophenone with benzaldehyde to form chalcone.&lt;/p&gt;</style></abstract><notes><style face="normal" font="default" size="100%">15th International Zeolite Conference, Beijing, PEOPLES R CHINA, AUG 12-17, 2007</style></notes></record></records></xml>
