Wang, Ren-Qi published the artcileChemically bonded cationic β-cyclodextrin derivatives and their applications in supercritical fluid chromatography, Application In Synthesis of 69097-99-0, the publication is Journal of Chromatography A (2012), 97-103, database is CAplus and MEDLINE.
Cationic β-cyclodextrin (CD) perphenylcarbamoylated derivatives were chem. bonded onto vinylized silica using a radical co-polymerization reaction. The derived materials were used as chiral stationary phases (CSP) in supercritical fluid chromatog. (SFC). Enantioseparations were successfully demonstrated on 14 racemates encompassing flavanones, thiazides and amino acid derivatives The electrostatic force between the analytes and the cationic moiety on β-CD derivative is important for retention and enantioseparation of the racemates. Aromatic cationic moiety on β-CD enabled better enantioseparations than aliphatic cationic moiety. Also the presence of acid additives would result in lower retention of the analytes but often assist the chiral resolutions
