| Abstract: | Thin solid films of doped poly(3-hexylthiophene) and poly(3-decylthiophene) undergo rapid conductivity degradation at elevated temperatures (110 °C). We have followed the changes in the electronic structure during thermal treatment by optical spectroscopy. We have also studied thin films of the materials, before and after heat treatment, by means of infrared and X-ray photoelectron spectroscopy. The results show that the materials are undoped by thermal treatment. Comparative studies on poly(3-methylthiophene) show that this polymer also undergoes thermal undoping, but at a much slower rate. |
