The chiral discrimination of β-cyclodextrin ((β-CyD) was demonstrated by measuring 270 MHz 1H-NMR spectra, using dl-pirprofen (PF) as a guest molecule.Upon binding to β-CyD, the induced 1H-chemical shifts of PF, particularly in the phenylpropionic acid portion, were significantly different between the d- and l-isomers, while no enantiomeric difference was observed in the abscence of β-CyD.
