    • N2-like transfer of the guest molecule from the complex to the empty tweezer-have to be taken into consideration for the observed exchange. Therefore, the observed activation enthalpy is either equal to or smaller than the dissociation enthalpy. The dynamics in the host-guest complexes are discussed in more detail for the complexes between tweezer T and 1,2,4,5-tetracyanobenzene or tropylium tetrafluoroborate as examples: Lobert, M.; Bandmann, H.; Burkert, U.; Büchele, U. P.; Podsadlowski, V.; Klärner, F.-G. Chem. Eur. J., in press.

    • note
    • The fact that the averaged signal of each proton (observed in the range of fast exchange) has to be the center of the two signals (observed for each proton in the range of slow exchange) allows the assignment of all bridgehead protons in the spectrum at -105 °C.
