A highly crowded perylene-cored oligoarylene processively transforms into π-extended chiral nanographenes with two helical breaches under Scholl's conditions. The acquisition of various intermediates implies a distinctive reaction pathway mainly involving the regioselective and sequential cyclization in the peri- and bay regions of the perylene core, and the complanation of the 1-phenyl[5]helicene intermediate module via 1,2-phenyl migration.
