Thanks to the presence of a π–electron conjugated system, a few organic polymers, such as polypyrrole (PPy), polyaniline (PANI), polythiophene (PTh), and relevant derivatives, are classified as semiconductors that become well conductive by partial oxidation or reduction. By following an improper analogy with inorganic semi-conductors this process has been called ‘doping’. For this peculiar characteristic, similar materials are called ‘intrinsically conducting polymers’ (ICPs). The structures of the most meaningful ICPs are displayed in Fig. 2.1.
