The synthesis of a functionally rigid [2]rotaxane incorporating π-electron rich 1,5-disubstituted naphthalene (NP) ring systems, encircled by the π-electron deficient tetracationic cyclophane, cyclobis(paraquat-p- phenylene), is described; in the solid state, the molecules of this donor-acceptor [2]rotaxane line themselves up in parallel π-π stacks of alternating NP ring systems and bipyridinium units, affording an interdigitated superstructure.
