| 摘 要： | Single-walled carbon nanotubes(SWNTs)have a high adsorption ability and nanoscale interactions.Cellulose trisphenylcarbamates possess high enantioseparation ability in high-performance liquid chromatography(HPLC).Single-walled carbon nanotubes mixed with cellulose trisphenylcarbamate are coated on the silica gel as chiral stationary phases and higher enantioseparation factors are obtained.After a single-walled carbon nanotube is linked to the 6-position of cellulose 2,3-bisphenylcarbamate,its enantioseparation resolution increases compared to that of the cellulose trisphenylcarbamate.It is the first time that SWNTs have been applied to enantioseparation.The results indicate that the single-walled carbon nanotubes are good promoters of chiral recognition.This method can be used to improve the enantioseparation efficiency of the polysaccharide chiral stationary phases. |
