Abstract
In this paper, we report the synthesis in one step of ordered (hexagonal phase) mesoporous silicas functionalized with two different organic groups [HS(CH2)3– and acac(CH2)3–] located in the pore channels. These materials were characterized by X-ray diffraction measurements, transmission electron spectroscopy, nitrogen adsorption analyses and solid state 13C and 29Si NMR spectroscopies. The bifunctionalization of the internal pore's surface by the organic groups was clearly evidenced by elemental analyses and chemical reactivity. In addition, we have shown that the organic groups were regularly distributed on the pore's surface.
