Abstract
The configuration of helical dicationic dyes 22+ with a dihydrodibenzoxepinone unit is stable, whereas the corresponding neutral electron donors 1 with a tetrahydrophenanthroxepinone skeleton easily undergo ring-flip. Thanks to their electrochemical bistability, electron exchange between 1 and 22+ is prohibited. Thus, the above electrochromic pairs 1/22+ can serve as new members of less well-explored redox-based chiral-memory units.
