摘要：

Poly(3-octylthiophene) has been stretched up to 5 times its original length. The state of orientation of stretch-oriented, free-standing films have been characterized by infra-red dichroism measurements and x-ray diffraction. The results shows that the crystalline regions are much more oriented than the amorphous regions. The x-ray diffraction pattern of the stretched films is also used in a discussion of the crystal structure of poly(3-octylthiophene). Furthermore, the optical anisotropy of oriented poly(3-octylthiophene) was studied by using thin films stretched on a polyethylene substrate. The intrinsic anisotropy of poly(3-octylthiophene) was estimated to be around 10.
