New heteroacenes, named coumarinacenes, have been designed, synthesized and characterized. They possess visible absorption and orange‐red emission that are far beyond those of benzo[ g ]coumarins. They exhibit deep HOMO energy levels, and reveal excellent thermal, photochemical and air stabilities as compared to tetracene/pentacene. Their preliminary thin‐film devices display encouraging transistor characteristics, moderate mobility and considerable environmental stability paving way into electronics.
