• We report the synthesis and characterization of two hexapole [7]­helicenes (H7Hs). Single crystal X-ray diffraction unambiguously confirms the molecular structure. H7H absorbs light, with distinct Cotton effect, from ultraviolet to the near-infrared (λmax = 618 nm). Cyclic voltammetry reveals nine reversible redox states, consecutively from −2 to +6. These chiroptical and electronic properties of H7H are inaccessible from helicene’s small homologues.
