Although attached via C=C double bonds, the substituents behave as molecular rotors. This is explained by their pronounced donor-acceptor character which lowers rotational barriers and allows for electronic control over the spinning rates inside the cage. The dynamic behaviour of the free ligands, assembled cages and host-guest complexes is compared with the aid of NMR experiments, X-ray structure analysis and molecular modelling.journal_article10.1039/c6cc04155h27484435000382119600021https://resolver.sub.uni-goettingen.de/purl?gs-1/13745openAccess
