Using nitrogen atoms in the perimeter of a hexacene will make the compound considerably more stable than its all‐hydrocarbon relative. In their Communication on page 8588 ff, U. H. F. Bunz and co‐workers report the synthesis of a tetraaza‐ and a hexaazahexacene using a palladium‐catalyzed cross‐coupling of a suitable diaminoanthracene or diaminophenazine derivative with dichloroquinoxaline. The obtained materials are potentially attractive for applications in organic electronics.
