(Figure Presented) The radical cation of carbon-sulfur [7]helicene is configurationally stable in solution at room temperature. In contrast to the radical cations of α-oligothiophenes, which form diamagnetic π-dimers at low temperature, the radical cation of this helical, cross-conjugated β-oligothiophene shows a low propensity toward dimerization.
