A supermolecular array consisting of a coordinating ring, a copper( I ) centre and a difunctionalized fragment threaded inside the ring is treated with a C 60 derivative to afford a rotaxane with two fullerenes as stoppers (right). The changes in the photophysical properties of the rotaxane with respect to the individual components, a methanofullerene and a Cu I complex, were assigned to the occurrence of intercomponent energy‐ and electron‐transfer processes.
