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).
