In order to better understand the chiral recognition mechanisms of positively charged cyclodextrin (CD) derivatives, synthesis, pKa determination by 1H nuclear magnetic resonance (NMR)-pH titration and a comparative capillary electrophoretic (CE) study were performed with two series mono-substituted cationic single isomer CDs. The first selectors mono-(6-N-pyrrolidine-6-deoxy)-β-CD (PYR-β-CD), ...
