基于X射线光纤图、偏振红外光谱和拉曼光谱，提出了碘掺杂聚3-烷基噻吩的晶体结构模型：聚噻吩链沿着链轴位移，形成沿着B轴延伸的隧道，其中I-5离子主要嵌入。从红外二向色性可以看出，噻吩环与碘分子之间的电荷转移产生了沿链轴沿着具有强跃迁偶极矩的极化子和双极化子.
Based on the X-ray fiber diagram, polarized infrared and Raman spectra, the crystal structural model of iodine-doped poly(3-alkylthiophene) has been proposed: polythiophene chains are displaced along the chain axis to give the tunnels extending along the b axis, in which the I-5 ions are mainly intercalated. The resultant charge transfer between thiophene rings and iodine molecules is considered to give polaron and bipolaron with intense transition dipole moments along the chain axis, as judged from the infrared dichroism.
