Abstract

Fast and furious: The mobile ring of a copper-complexed [2]rotaxane incorporates an endocyclic but nonsterically hindering bidentate chelate. The rotaxane axis contains three different chelates (see picture), and both terminal coordination sites are separated by about 23 Å. The shuttling motion is triggered by oxidation or reduction of the copper center and is as fast as that in a related two-station rotaxane whose terminal stations are 10 Å apart.
