Research output: Contribution to journalArticlepeer-review


Vivid color change from intense yellow to deep purple was observed upon electrochemcal oxidation of the title donor <B>1</B> to bis(Michler's hydrol blue)-type dication <B>1</B><SUP>2+</SUP>. Since the interconversion was also accompanied by drastic geometric changes, configurational stability of the helical π-arrangement is modified upon redox reactions.
