 Abstract: A stable chiral hetero[4]helicene radical cation was synthesized and characterized by UV-Vis absorption and EPR spectroscopy as well as X-ray crystallography. For the first time a combination of chiroptical methods involving ECD, ORD, and VCD, supported by quantum mechanical predictions, enabled the elucidation of the absolute configuration of such open-shell helical species.
