Abstract

The first example of one-electron oxidation of thia-bridged triarylamine heterohelicenes to the corresponding exceptionally stable radical cations, fully characterized, as hexafluoroantimonate salts, by means of UV-Vis, EPR, ENDOR, density functional theory calculations and X-ray analyses, is reported. Chemical and electrochemical reversible redox processes are solidly demonstrated.
