摘要: A series of [Pd2L4] coordination cages featuring endohedral functionalities in central backbone positions was synthesized. Although attached via CC 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 spinning rates inside cage. The dynamic behaviour free ligands, assembled host–guest complexes compared with aid NMR experiments, X-ray structure analysis modelling.
