    Abstract Ruthenium‐catalyzed butadiene‐mediated benzannulation enabled the first synthesis of 3,10‐(di‐tert‐butyl)rubicene and its N‐doped derivatives as well as preliminary studies on their photophysical properties. Unlike the parent rubicene and 3,10‐(di‐tert‐butyl)rubicene, which adopt classical herringbone‐type packing motifs in the solid state, the N‐doped congener7 bdisplayed columnar packing with an alternating co‐facial arrangement of aromatic and heteroaromatic substructures.
