A series of α-hydroxyalkylferrocenes (ferrocenemethanol [FcCH 2 OH], α-hydroxyethylferrocene, and 1,1'-ferrocenedimethanol) have been shown to incorporate into highly oxidized films of poly(aniline) [PAn]. Surface immobilization is readily evident in cyclic voltammetric studies by the rapid growth of a pair of sharp redox waves at E 1 / 2 =0.455 V versus SCE in the case of FcCH 2 OH. A general mechanism for the attack of α-hydroxyalkylferrocenes on oxidized PAn is inferred from the electrochemical data.
