Abstract

A cubic coordination cage acts in MeCN as a host for neutral organic guests which contain an H-bond-accepting group that interacts with the internal surface of the cage. The different thermodynamic contributions to guest recognition and the kinetics of both guest binding and reorganization inside the cavity have been analyzed in detail by 1H NMR spectroscopy, which is facilitated by the paramagnetism of the host cage.
