Reverse shuttling in a fullerene-stoppered rotaxane

Org Lett. 2006 Oct 26;8(22):5173-6. doi: 10.1021/ol062277v.

Abstract

The preparation and characterization of a solvent-switchable rotaxane that shuttles in the opposite direction to that expected are reported. The reverse shuttling is confirmed by NMR spectroscopy and can be monitored by cyclic voltammetry. The electrochemically generated anions on the fullerene moiety are stabilized by the closer proximity of the macrocycle.
