| 英文摘要 | phenyl-functionalized mesoporous ethane-silicas with spherical morphology were synthesized by one-step co-condensation of phenyltrimethoxysilane (ptms) and 1,2-bis(trimethoxysily)ethane (btme) using a triblock copolymer eo20po70eo20 (p123) as template with the aid of a co-surfactant (cetyltrimethylammonium bromide, ctab) and a co-solvent (ethanol) in acidic medium. powder x-ray diffraction (xrd), nitrogen sorption measurement and scanning electron microscopy (sem) show that phenyl-functionalized ethane-silica has wormhole-like mesostructure and perfect spherical morphology. the chemical stability of phenyl-functionalized mesoporous ethane-silica in basic medium is greatly improved owing to the ethane groups bridged in the mesoporous framework. this work also demonstrates that the phenyl-functionalized mesoporous ethane-silica spheres are excellent packing materials for potential application in the reversed-phase high-performance liquid chromatography (hplc).
