Schematic representation of the chiral discrimination process by CDs. In (a), a system is shown in which the CDs migrate in the opposite direction to the EOF, so that the enantiomer involved in the more stable complex ((S)-Enantiomer@CD, correlated with ΔG1), has a longer time of migration. In (b), a system is shown in which the CDs migrate in the same direction as the EOF, so that the enantiomer involved in the more stable complex ((R)-Enantiomer@CD, correlated with ΔG2), presents a shorter migration time.
