Ironing with iron(III) chloride: A bottom‐up organic synthesis in solution to synthesize defect‐free graphene ribbons that cannot be obtained by top‐down methods such as lithography or unzipping of carbon nanotubes is described by K. Müllen and co‐workers in their Communication on page 2540 ff. Three‐dimensional polyphenylene precursors with a unique kinked backbone enable full planarization into a rigid ribbon in a single reaction step. This cyclodehydrogenation is achieved by an intramolecular Scholl reaction with FeCl 3 .
