Abstract Novel surfactants containing an alkoxysilane group and an amino acid residue have been synthesized. Using these surfactants as templates, mesoporous silica/surfactant covalent-composites were prepared. Selective removal of the alkyl chain of the template provided mesoporous silica with inner surface densely covered by the amino acid residue. Successful modification process was confirmed by XRD, FT-IR, TEM and TGA analyses.
