Structurally well-defined zigzag-edged nanographenes hold great potential in nanoelectronics and spintronics. Herein, we reported the synthesis and characterization of a dibenzocircumpentacene derivative (1) featuring multiple zigzag edges, achieved through oxidative cyclodehydrogenation of a bisdibenzophenanthryl-p-terphenyl-based precursor. Because of peri-benzannulation, 1 exhibits a closed-shell singlet ground state, considerably enhanced stability, and a more localized aromatic characteristic. This work will shed new light on the synthesis of novel zigzag-edged nanographenes with tunable electronic properties and remarkable stability.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
