These results clearly demonstrate that the CBPQT 4+ ring can cross both an MPTTF 2+ and a TTF 2+ electrostatic barrier and that the free energy of activation required to cross MPTTF 2+ is ca. 1H NMR spectroscopy carried out in CD 3CN at 298 K on a chemically oxidized sample of 1⋅MPTTF 4+ revealed that the metastable state 1⋅TEG 8+ is only short-lived with a lifetime of a few minutes and it was found that 70 % of the positively charged CBPQT 4+ ring moved from 1⋅TEG 8+ to the HQ station, while 30 % moved to the much weaker OP station. Following tetra-oxidation of 1⋅MPTTF 4+, a high-energy state of 1 8+ was obtained (i.e., 1⋅TEG 8+) in which the CBPQT 4+ ring was located on the TEG linker connecting the di-oxidized TTF 2+ and MPTTF 2+ units. The electrochemical studies showed that CBPQT 4+ in 1⋅MPTTF 4+ undergoes ring translation as result of electrostatic repulsion from the oxidized MPTTF unit. The spectroscopic data revealed that the majority (77 %) of the tetra-stable rotaxane 1 4+ exist as the translational isomer 1⋅MPTTF 4+ in which the CBPQT 4+ ring encircles the MPTTF station. The rotaxane was characterized in solution by 1H NMR spectroscopy and cyclic voltammetry. The TTF and the MPTTF stations are located in the middle of the dumbbell component and are connected by a triethylene glycol (TEG) chain in such a way that the pyrrole moiety of the MPTTF station points toward the TTF station, while the TTF and MPTTF stations are flanked by the OP and HQ stations on their left hand side and right hand side, respectively. The dumbbell component is comprised of an oxyphenylene (OP), a tetrathiafulvalene (TTF), a monopyrrolo-TTF (MPTTF), and a hydroquinone (HQ) unit, which can act as recognition sites (stations) for the tetra-cationic cyclophane cyclobis(paraquat- p-phenylene) (CBPQT 4+). A tetra-stable donor–acceptor rotaxane 1⋅4PF 6 has been synthesized.
