Diblock metallopolymer polyelectrolytes containing the two redox‐robust cationic sandwich units [CoCp′Cp] + and [FeCp′(η 6 ‐C 6 Me 6 )] + (Cp = η 5 ‐C 5 H 5 ; Cp′ = η 5 ‐C 5 H 4 ‐) as hexafluorophosphate ([PF 6 ] − ) salts are synthesized by ring‐opening metathesis polymerization using Grubbs' third generation catalyst. Their electrochemical properties show full chemical and electrochemical reversibilities allowing fine determination of the copolymer molecular weight using Bard–Anson's electrochemical method by cyclic voltammetry.
