Abstract
The electron accepting 1-methyl-4,5-dicyanoimidazole group was attached to vinyl polymers, via an alkoxy link, by nucleophilic aromatic substitution (NAS) of 1-methyl-2-fluoro-4,5-dicyanoimidazole (1) with poly(vinyl alcohol), or conventional polymerizations of vinyl monomers containing 1-methyl-2-oxo-4,5-dicyanoimidazole. The cyclic voltammetry (CV) studies show that monomeric and oligomeric model compounds are electrochemically quasi-reversible and the degree of reversibility decreases as dicyanoimidazoles become more proximate within a molecule. On the other hand, the polymers show much less reversible reduction waves at −2.6∼−2.7 V vs Ag/Ag+, suggesting that there are chemical reactions among the pendent groups reduced at relatively high potential. © 2000 John Wiley & Sons, Inc.
