High dilution techniques have been employed to construct a series of charged flexible cyclophanes comprised of
-electron-rich hydroquinone and -electron-deficient bipyridinium residues linked by polyether spacer units of varying length: significant conformational changes, leading to intramolecular and intermolecular interactions between the -donors and -acceptors, have been observed—as evidenced by X-ray crystallographic and variable temperature 1H NMR and 2D ROESY spectroscopic investigations—within the series of the cyclophanes both in the solid and solution states as a result of increasing the lengths of the polyether spacer units.
