E. Graf et al., PROBING PERISTATIC CHIRALITY OF ALKALINE CATIONS - NMR-STUDY OF ALKALINE BOROCRYPTATES, Chemical communications, (15), 1997, pp. 1459-1460
Enantiomeric differentiation of chiral borocryptates using NMR spectro
scopy in a chiral liquid crystalline medium is achieved using differen
t NMR probes localised both on the receptor and on the substrate; the
observed chirality at the substrate is described as being induced by t
he spiroborate junction and mediated by the peristatic chirality of th
e cavity.
