Steps:

2.3.1. Synthesis of heptyl vinyl benzyl viologen bis(hexafluorophosphate)(HBV(PF6)2)

As reported in the literature [39], monoheptyl viologen bromide(MHVBr) was synthesized as follows: a mixture of 4,4′-bipyridine(1.825 g, 12 mmol) and heptyl bromide (2 g, 10 mmol) was dissolved inACN (20 ml) and stirred at 50 °C for 72 h. MHVBr was isolated from themixed solution by filtering, washed with diethyl ether and dried undervacuum at 50 °C for 24 h. Then, the arylation of MHVBr utilizing DMFas a solvent to prepare heptyl vinyl benzyl viologen bromide chloride(HBVBrCl) was conducted in the similar fashion as MHVBr. HBV(PF6)2was synthesized by an anion exchange with the HBVBrCl and excessKPF6 dissolved in DIW. The white precipitated HBV(PF6)2 was obtained,separated through filtration, and washed with DIW after stirringfor 24 h. Ultimately, HBV(PF6)2 was collected after drying under vacuumat 50 °C for 24 h.
