In combination with bulky substituents at the core, fourfold benzannulation at the cata ‐positions stabilizes a nonacene sufficiently to allow its isolation and characterization by 1 H NMR and X‐ray analysis. The four benzo units blueshift the absorption spectrum in comparison to a solely linear nonacene, but significantly increase the stability in the solid state.
