Mortimer, Roger J.; Dillingham, Joanne L. published an article in 1997, the title of the article was Electrochromic 1,1′-dialkyl-4,4′-bipyridinium-incorporated Nafion electrodes.Application of 52243-87-5 And the article contains the following content:

The sym. 1,1′-dialkyl-4,4′-bipyridynium salts (alkyl = Me, Et, Pr, Bu, n-pentyl, n-hexyl) can be electrostatically incorporated into Nafion films to produce electrochromic electrodes. A trend from purple to pink in the color of the radical-cation redox state is observed This has been interpreted by in situ visible absorption spectroelectrochem. measurements as being due to a higher incidence of radical-cation dimers in the Nafion films with increase in alkyl chain length. Response times for coloration are shorter than for bleaching, owing to the slower phys. diffusion of the radical-cation dimers. The 1,1′-di-n-heptyl-4,4′-bipyridinium system was not incorporated into the Nafion structure and impede extensive incorporation into the bulk of the anionic polyelectrolyte. The presence of an inner Prussian blue layer in a Prussian blue/Nafion (1,1′-dialkyl-4,4′-bipyridinium) bilayer configuration permits five-color polyelectrochromicity at a single electrode. The experimental process involved the reaction of 1,1′-Dipropyl-[4,4′-bipyridine]-1,1′-diium bromide(cas: 52243-87-5).Application of 52243-87-5
