Stabilization of large (aza)acenes is a necessary challenge to unlock their full potential. “Clipping” an azaacene into a large ring complements stabilization by trialkylsilylalkynylation as demonstrated by Jan Freudenberg, Uwe H. F. Bunz and co‐workers in their Communication on page 9270. “Jacketed” azapentacenes display superior photochemical and oxidative stability compared to their bis(TIPS‐ethynyl)‐substituted congeners.
