Periodic mesoporous organosilica from zwitterionic precursors

Abstract

International audienceMesoporous hybrid silica bearing zwitterionic species were synthesized via template directed hydrolysis-polycondensation reactions from zwitterionic ammonium-sulfonate precursors. The formation of nanostructured phases involves specific precursor-template interactions. The obtained materials are efficient heterogeneous catalysts in Biginelli reactions
