英文摘要the bifunctionalized mesoporous organosilica spheres with trans-(1r,2r)-diaminocyclohexane (dach) in the pore were synthesized and their application as chiral stationary phase in high-performance liquid chromatography (hplc) was demonstrated. bifunctionalized mesoporous organosilica spheres with narrow particle size distribution of 5-7 mu m were prepared by the co-condensation of n-[3-(triethoxysilyl)propyl]-trans(1r,2r)-diaminocyclohexane (m(propyl)) with 1,2-bis(trimethoxysilyl)ethane (btme) in basic medium using octadecyltrimethyl ammonium chloride (c(18)tac1) as structural directing agent and ethanol as co-solvent. the morphologies of the bifunctionalized mesoporous organosilicas were sensitive to the molar fraction of m(propyl). at higher m(propyl)/btme molar ratio, the bifunctionalized organosilica spheres with ordered mesoporous structure can be formed in a wide range of synthetic conditions. when the molar percent of m(propyl)/(m(propyl)/btme) is less than 20, the formation of spheres could be hardly observed. the structural order of the materials mainly depends on the base concentration and mpropyi/btme molar ratio in the initial sol mixture. a column packed with the bifunctionalized mesoporous organosilica spheres exhibits higher selectivity and resolution for racemic amino acids than that packed with dach-sio(2) prepared by conventional post-synthesis grafting method.
