Carboxylic-functionalised large-pore mesoporous etahne-brdged organosilica is synthetised and characterised. Carboxylic groups have been incorporated in ethane-bridged PMO by one-pot synthesis using a triblock copolymer as template; their pKa measured by titration is higher than that of same groups incorporated in SBA-15.

Abstract
Carboxylic-functionalised large-pore mesoporous etahne-brdged organosilica is synthetised and characterised. Carboxylic groups have been incorporated in ethane-bridged PMO by one-pot synthesis using a triblock copolymer as template; their pKa measured by titration is higher than that of same groups incorporated in SBA-15.
