In addition to these molecular shuttles, other dynamic supramolecular systems have been reported with the development of molecular trains utilizing catenanes [79], where one catenane ring can continually cycle around another via several stations. Sauvage and co-workers ]80-83] reported electrochemically induced ring gliding in copper catenanes which exploits the differing preferred geometries associated with Cu(I)/Cu(II).
