Silica materials of MCM type, characterised by highly ordered pore structure, attract increasing attention. Due to high specific surface and high total pore volume these mesoporous silicas may be used as specific sorbents, host materials for biologically active substances or support for many active species in catalysis. The co-condensation of tetraethoxysilane and an organo-(C18)-silane in the presence of surfactant micellar template gives organically functionalised silica material of highly hydrophobic character and hexagonally arranged cylindrical pores. Characterisation of the surface species for synthesized materials was investigated by employing the FT-IR/PAS technique.
