摘要：

Doping, thermal dedoping and degradation processes in poly(3-octylthiophene) and poly(3-decylthiophene) have been studied. The doped state is unstable. The dedoping decay rate of conductivity depends on the dopant, dedoping degree (or conductivity) and temperature. The temperature dependence follows the Arrhenius law. The most stable dopant studied was FeCl3. Other dopants, I2, PF6- and organic acid anions had orders of magnitude higher conductivity decay rates. Dedoping is associated with degradation of the polymer, especially when doped with FeCl3.
