Vinylbenzyl viologen

The low redox potential of Af,AT-dialkyl-4,4 -bipyridinium salts (viologens) has prompted their incorporation into various polymeric systems. Addition polymerizable viologens have been prepared, for example, by reaction of monoalkylated bipyridyl with vinylbenzyl chloride (Scheme 30). Aqueous free radical polymerization and copolymerization of... [Pg.285]

In a slightly different system, Matsuo14 149 also examined electron transfer to a polymer supported viologen [ poly(JV-vinylbenzyl-7V -n-butyl-4,4 -bipyridinium PV2+] via a zwitterionic viologen (N,N -bis(3-sulfonatopropyl)-4,4 -bipyridinium PSV). [Pg.505]

Copolymers of vinyl viologens, such as N-vinylbenzyl-N -alkyl and benzyl and N-(x-mefliacroyloxy)propyl-N -propyl-4,4 -bipyridinium dihalides and polar aprotic comonomers, such as N- vinyl-2-pyrrolydone or N.N dimethylacrylamide exhibit a strong color formation upon irradiation. One such copolymer can be illustrated as follows ... [Pg.305]
