Pyrrole- and Azulene-Fused Azacoronene Dication with 22π+6π Aromatic Rings
17 Oct 2019
Polycyclic heteroaromatic molecules are a highly useful class of organic materials. In this study, synthesis of a new azacoronene, in which both pyrrole and azulene moieties are circularly fused, was achieved in just three steps. This new azacoronene exhibited multistep reversible oxidations under electrochemical and chemical conditions. Formation of an aromatic 22π-electron conjugation and a tropylium cation (6π-electron conjugation) in the dicationic state played a key role in stabilizing this cationic species.
