Due to the similarity of the optical enantiomers,enantioseparation is perhaps the most subtle to achieve.Thus,developing efficient chiral separation techniques are highly desirable.Chiral biosensors and enantioseparation technologies based on carbon nanomaterials (e.g.carbon nanotubes,graphene,fullerene,etc.) have attracted great attention in recent years[1-10].However,the interactions among the carbon nanomaterials and the analytes have not been futher investigated.In this study,a thin-layer chromatographic (TLC) enantioseparation method was used to separation racemates.A series of carbon nanomaterials and their composites were used to realize highly resolution of two racemic drugs: propranolol and ofloxacin.The enantio-sensitivity toward the racemic drugs was found to be more efficient and available.The resolution conditions were also optimized.UV-vis absorption spectrometer were used to analyze the solutions of different β-cyclodextrin derivatives and carbon nanotubes (CNTs).Intramolecular π–π stacking interactions and hydrogen bonding might make great contributions to the enantioseparation.
