On January 31, 1996, Satoh, Hideharu; Tokuda, Koichi; Ohsaka, Takeo published an article.Synthetic Route of 52243-87-5 The title of the article was Observation of intermolecular charge-transfer spectra for propyl viologen dihalides in a series of polyether media. And the article contained the following:

1,1′-Dipropyl-4,4′-bipyridinium diiodide (PV2+·2I-) in a series of polyethers (PEOs, HO(CH2CH2O)nH, n = 1 ∼ 14) gave an intermol. charge-transfer spectrum, which shifted to longer wavelength with larger absorbance in less polar medium, in the visible region. An increase in temperature resulted in an increase in absorbance as a result of an ion-dipole interaction between PV2+ cation and polyether solvent. The experimental process involved the reaction of 1,1′-Dipropyl-[4,4′-bipyridine]-1,1′-diium bromide(cas: 52243-87-5).Synthetic Route of 52243-87-5
