Facile Synthesis of Highly Stable Tetraazaheptacene and Tetraazaoctacene Dyes

Stable, tunable, and colorful: The straightforward synthesis of highly stable π-extended tetraazaheptacene and tetraazaoctacene dyes is reported. The oxidation behavior of pyrene-based azaacenes and the third reduction wave for pyrene-based azaacenes with <11 linearly-fused rings is also observed for the first time.
