| 英文摘要 | we describe the synthesis of hybrid monolith with hierarchically macro-mesoporous structure by a sol-gel process from the mixture of 1,4-bis(triethoxysilyl)benzene (bteb) and tetraethoxysilane (teos) using poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (p123) as structure directing agent under acid medium. the ordered mesoporous structure is embedded in the skeleton of the well-defined co-continuous macropore of the hybrid monolith. the influence of aging condition, acidic concentration, p123/si ratio and tmb/p123 ratio on the macro- and meso-structure of the resultant monolith was investigated in details. the three-successive aging processes are necessary for the mesostructural order of the monolith to survive the surfactant removing process. the well-defined co-continuous macropore could be formed with the aid of tmb, which probably delays the phase separation rate during the sot-gel process through enhancing the interaction between the hydrophobic bteb with p123 surfactant micelles. the macro-mesoporous hybrid monolith with phenylene bridged in the mesoporous framework may have potential application as a novel kind of stationary phase for high performance liquid chromatography (hplc).
