using electrochemical and spectroscopic techniques. It was determined that the stability of the radical film deposited on cathodic reduction of aqueous solutions of these salts may be strongly influenced by symmetry, steric, and electronic factors. From this basis, it was possible to design a viologen, 1,1′-bis-(2-methylbenzyl)-2-methyl-4,4′-bipyridinium dibromide (9), having electrochromic properties
