Abstract:A negatively curved aza‐nanographene (NG) containing two octagons was synthesized via a regioselective and stepwise cyclodehydrogenation procedure, where 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, enabling the exploration of structure‐property relationship by photophysical, electrochemical and conformational studies. Moreover, the assembly of the octagon‐embedded aza‐NG with … Show more
