[2] and [3] hybrid rotaxanes are reported based on {Ti 7 M} rings (M is a trivalent metal such as Fe III or Ga III ). NMR studies show that [2]rotaxanes can act as molecular shuttles, while EPR studies of [3]rotaxanes show weak interactions between the paramagnetic components of the supramolecular assemblies.
