Scholarcy highlights

  • In the present work the electrochemical polymerization of pyrrole derivatives has been performed in order to identify the conditions for obtaining intrinsically conducting polymers, checking film morphology and conductivity
  • The conductivity decreases as the alkyl side chain becomes longer
  • When the polymerization is performed at low monomer concentration, the surface properties of P3DP(ClO4) are very poor and the conductivity is only 10−3 S cm−1
  • The voltammetric evolution observed during cycling is studied under different experimental parameters
  • P3DPNO3, conductive, can be switched from the oxidized form to the reduced one only a few times in acetonitrile and never in propylene carbonate, showing the difficulty of the polymer in being reduced and oxidized several times
