Abstract

The dimerization of dendrimers that contain a single 4,4′- bipyridinium (viologen) unit, upon one-electron reduction, is strongly enhanced by the presence of the host cucurbit[8]uril. This behavior is attributed to the formation of a stable inclusion complex between the host and two π-stacked viologen radical-cation guests-the one-electron-reduced form of viologen (see scheme).
