Considering a site‐potential difference between amine and imine, we investigate the self‐consistent‐variation ground and defect state of the emeraldine‐base polymer in the framework of an extended Ginder‐Epstein model. The results show that the model with a site‐potential difference α im — α am = 0.8 eV can reproduce most of the observed data in the polymer. The 1.4 and 0.9 eV peaks of photoinduced absorption in the EB polymer can be attributed to the charged combined polarons P — and P + , respectively.
