摘要：

Poly(3-alkylthiophenes) are found to undergo continuous structural transformations upon doping with iodine vapor. Doping is characterized by an initial increase and then a reduction in the interlayer repeat. This process involves cooperative motions of the alkyl chains, the polymeric backbones, and the dopan ions, whereby alkyl chain interdigitation is initially suppressed and then encouraged. Structure factor calculations identify the specific molecular motions by both polymer and dopant.
