    Notes: Abstract The interactions between β-cyclodextrin and a hydrosoluble polymer carrying hydrophobic residues: poly(4-sodium styrenesulfonate) have been studied. Several techniques were used: capillary viscosimetry, circular dichroïsm, and NMR spectroscopy. The results proved that the aromatic residues of NaPSS were included in the cavity of β-cyclodextrin, and that, in addition, a network of hydrogen bonding between sulfonic acid residues and the hydroxyl groups of β-cyclodextrin occured.

    High performance liquid chromatography of structural isomers using a cyclodextrin-poly(allylamine) coated silica column (1995)
    Springer
    Chromatographia 41 (1995), S. 424-430

    ISSN: 1612-1112
    Keywords: Liquid chromatography ; β-cyclodextrin bonded phase ; Polymeric stationary phase ; Phenolic compounds ; Isocratic elution

    Topics: Chemistry and Pharmacology
    Notes: Summary High performance liquid chromatography (HPLC) separation of substituted phenols by isocratic elution was investigated using a β-cyclodextrin-bonded column. The HPLC support was prepared in-house. This support was based on silica beads coated with a β-cyclodextrin-containing poly(allylamine). The retention behavior of some substituted phenol isomers and aromatic compounds was studied. The contribution of the amino groups of the polyamine and of the β-cyclodextrin cavity to the separation process is discussed. Two retention mechanisms, inclusion complex formation and acidbase interaction, were found. The effect of the composition and pH of the mobile phase on the separation was also examined.
