Tautomerization of the starting pyrazinacene due to the presence of a reduced pyrazine ring contained within an octaazatetracene chromophore led to mixtures of isomers, and factors affecting the relative yields of these isomers were considered. Isomer population can be described by a two‐step reaction model where initial N‐alkylation affects the reactivity of the remaining nitrogen atoms available for subsequent alkylation. A discrete soluble non‐isomerizable phenanthroline‐fused pyrazinacene was also prepared and the activity of its Ru(bpy)2 complex as a photosensitizer for dye‐sensitized solar cell application was investigated. The compounds reported illustrate the unusual reactivity of reduced pyrazinacenes and also their potential as photosensitizers.
