Outline of Final Research Achievements

Novel molecular science was conducted for achieving electrochemical Coulombic efficiency higher than 10000%. Target molecules showed electrochemical oxidative cycloreversion isomerization with ideal zero-order kinetics independent of concentration of substrate. Chemical modification supported systematic stabilization of O+ component and rapid fading isomerization was observed without electrochemical current, indicating Coulombic efficiency higher than 10000%.
