Electrochemically and Photochemically Driven Ring Motions in a Disymmetrical Copper [2]-Catenate

摘要

By applying the three- disymmetrical templte effect of copper(I), previously used for making various interlocking ring systems, a new disymmetrical [2]-catenate has been made which consists of two different interlocking rings. One ring contains a 2, 9-diphenyl-1, 10-phenanthroline (dpp) unit whereas the other cycle incorporates both a dpp motif and a 2, 2', 6,, 2"-terpyridine (terpy) fragment, the coordination site of these two chelates pointing toward the inside of the ring.
