| 英文摘要 | highly monodisperse 1,3-phenylene-bridged hybrid organosilica spheres (m-phs) were synthesized by co-condensation of tetraethoxysiliane (teos) and 1,3-bis(triethoxysilyl)benzene (1,3-bteb) using dodecylamine (dda) and cetyltrimethylammonium bromide (ctab) as templates. in this method, three important factors are the surfactiant, the ethanol-water volume ration and teos/1,3-bteb molar ration. their effects on the spherical particle morphologies were investigated systematically to optimize the synthesis conditions. with the optimal method, m-phs was prepared with uniform particles in a narrow range 1.8 similar to 2.5 mu m. likewise, highly monodisperse 1,4-phenylene-bridged hybrid organosilica spheres (p-phs) were synthesized from teos and 1,4-bis(triethoxysilyl)benzene (1,4-bteb) to compare the chromatographic properties with m-phs. both two hybrid materials can be directly used for reversed-phase high-performance liquid chromatography (rp-hplc), showing high column efficiency, and the m-phs stationary phase exhibits a much longer retention time and better separation ability for some aromatic compounds. |
