摘要：

The formation of a mesophase in alpha-sexithienyl is reported which cannot be identified as either a nematic or smectic phase. On heating. it is also shown that, through careful control of the reaction conditions, crystalline polythiophene comparable in quality with that prepared by electrosynthesis or other synthetic methods can be obtained. The materials are studied using high-temperature X-ray diffraction and differential scanning calorimetry.
