The electrochemical reduction and oxidation of MBBA were studied by cyclic voltammetry and by controlled potential coulometry. The reduction in DMF leads to the formation of the radical anion which decomposes with a half‐life of about 4 sec, apparently by both ec and ece pathways. The oxidation product was unstable on the time scale of this study. The possible importance of electrode reactions in interpreting the dynamic scattering phenomenon in nematic liquid crystals is suggested.
