Abstract

Vivid color change from intense yellow to deep purple was observed upon electrochemcal oxidation of the title donor 1 to bis(Michler’s hydrol blue)-type dication 12+. Since the interconversion was also accompanied by drastic geometric changes, configurational stability of the helical π-arrangement is modified upon redox reactions.
