Electrochemical reduction of an azoniahelicene affords a dimer, accompanied by a strong
change in the electronic circular dichroism. The fast dimerisation event leads to a> 500 mV
shift of the oxidation potential, affording a large area of bistability, where the chiroptical
signal only depends on the redox history.
