Novel conducting polyaniline bearing functional groups

A copolymer formed from aniline and o-aminobenzylamine (ABA) was electroche mically synthesized from a solution of ABA and aniline with a mole ratio of 85.15. Its properties were studied by cyclic voltammetry. Relative conduct ivity measurements have been carried out showing that the copolymer's condu ctivity can be switched in the same way as that of poly(aniline) (PANI); th ey also indicate the presence of primary amino groups that allow a later de rivatization. Ferrocene carboxaldehyde (FeCp2CHO) was coupled to the copolymer showing th e presence of primary amino groups. This modified polymer also has snitchin g conductivity properties.
