Precise control of covalent bonding in nanographene is crucial for tuning its structure-dependent properties and enabling advanced functional materials. Herein, we report a nitrogen-doped nanographene featuring a C2-symmetric bilayer framework via incomplete Scholl oxidation. Structural, spectroscopic, and computational analyses reveal distinct optical behavior, environmental responsiveness, and quasi-reversible redox characteristics. The inability to resolve enantiomers highlights rapid chiral inversion. These findings offer valuable insights into designing stimuli-responsive heteroatom-doped nanographenes through covalent bond modulation.
