It is observed that reversible redox behavior of poly(I-co-Py)s shifts to more positive potentials with the increasing amount of I in the comonomer mixture, indicating formation of a copolymer. It is also found that increasing the ratio of I in the comonomer mixture decreases the conductivity of the obtained polymer films. The dark electrical conductivity measurements in the temperature range of 300-100 K revealed the extrinsic type of conduction with activation energy values being in the range of 82.3-16.9 meV.
