For instance, one nitro-group on one side of the porphyrin
cage compound leads to a selectivity of 67% major product
and 33% minor product, whereas two nitro-groups on the
same side of the host already increases this selectivity to
80% major and 20% minor product. Lastly, we have shown
that the EXSY studies are also applicable to exchange
studies with guests containing a polymer chain (H22/VP).
Furthermore, we determined that full dissociation as well as
slippage takes place and that the slippage-rate constant
was in the same range of magnitude as the rate constant
for exchange with a smaller guest (H22/V1), which confirms
