We will describe preliminary results of a study designed to determine if the desirable redox and electronic properties of viologens and polyaromatic hydrocarbons (PAHs), respectively, are retained when these two groups are fused together to make new materials. Viologens are dialkylated salts of 4,4’-bipyridines. Methyl viologen is the prototypical example that undergoes reversible electron transfers to generate stable dicationic, radical-cation and neutral redox states. Viologens have found use as redox indicators, components of supramolecular structures, as herbicides, and as electron transfer shuttles. PAHs have been widely explored as components of flexible electronic devices because of their propensity to exhibit high electron mobilities. We will present preliminary computational, photochemical, and electrochemical results for a new series of phenanthrenyl viologens, <b>PhV<sup>2+</sup></b>. We will also compare these results to the computational and photochemical properties of the 3,8-diazaphenanthrene precursors and to the electrochemical behavior of methyl viologen.
