摘要：

While soluble in many organic solvents, bipyridilium systems typified here by cyanophenyl-paraquat (CPQ) often deposit the mono-reduced and di-reduced species in a manner dependent on anion, with attendant complexity of electrochemistry. Factors governing this important electrochromic process for CPQ are examined by cyclic voltammetry and spectroelectrochemical study. The outcome appears to be the resultant of lattice forces, charge-transfer interaction, and the anion role in CPQ (dication) micellisation. © 1990.
