Cobaltocene electrode films prepared by electropolymerization of (Co(C5H4CCl=CHCHO)2)PF6.
A new cobalticinium salt [Co(C5H4CCl=CHCHO)2]PF6 gives electroactive films on electrode surfaces by electroreduction in n-Bu4NI–MeCN and the formed films act as a one-way charge-carrier for the redox reactions of solution species.
