Intramolecular Scholl reaction of carbazole derivatives afforded highly strained azahelicenes and azahepta[8]circulene, which was transformed into dibenzodiaza[8]circulenes. The diaza[8]circulene structure was characterized for the first time by X-ray diffraction analysis, which revealed the saddle-shaped π-conjugated polyaromatics.
