| Popis: | Two new BINOL-based chiral crown ether/ammonium complexes are studied by travelling-wave ion-mobility spectrometry. Homo- and heterochiral crown ether/ammonium complexes differ in their collision cross sections, and these differences go along with changes in hydrogen bonding as revealed by gas phase H/D-exchange experiments. Applications for the determination of enantiomeric excess are discussed. |
