Outline of Final Research Achievements

The chloranilate is one of anilate derivatives, which shows the multi-step redox property. Thus, both dinuclear dysprosium(III) and mononuclear cobalt (II) complexes with the chloranilate as the bridged were synthesized. Both complexes can reversibly control spin and/or electronic state by the electrochemical procedure, which is confirmed by the cyclic voltammetry measurement.
