A negatively curved aza‐nanographene (NG) containing two octagons was synthesized by a regioselective and stepwise cyclodehydrogenation procedure, in which a double aza[7]helicene was simultaneously formed as an intermediate. Their saddle‐shaped structures with negative curvature were unambiguously confirmed by X‐ray crystallography, thereby enabling the exploration of the structure–property relationship...
