摘要: The thioether-bridged mesoporous organosilicas with different mesostructures could be controllably synthesized by simply tuning molar ratio of the two precursors in Si-P123-NaAc-HAc-ethanol-H2O-systems. Mesophase transformation from highly ordered 2-D hexagonal structure to mesostructured cellular foam with vesicle-like structure as an intermediate phase is clearly observed when the molar ratio of bis[3-(triethoxysily)propyl]tetrasulfide (TESPTS)/tetramethoxysilane(TMOS) is successively increased.Because of the low hydrolysis and condensation rate of TESPTES under buffer solution, TESPTES can act both as aswelling for p123 surfactant micelles and co-agent for the formation of microemulsion with p123 syrfactant micelles. Our synthetic metnod provides a novel mild synthetic method for the controllable synthesis of mesoprous organosilicas with different mesostructure.
