A process for preparing organic semiconductor, which comprises doping an acetylene high polymer having a fibril structure with a specific electron-accepting compound. Conventional electron-accepting compounds are highly toxic and provide conductive acetylene high polymers which do not always exhibit a sufficiently high electric conductivity, which have a mechanical strength seriously reduced by the doping, and which have an insufficient heat resistance. The use of a specific, the low-toxic electron-accepting compound of the present invention provides a conductive acetylene high polymer having an enhanced electric conductivity and good flexibility and heat resistance. This conductive acetylene high polymer is a p-type semiconductor enabling to freely control the electric conductivity within the range of 10-9 to 103Ω-1.cm-1 and is useful as a material for conductive materials, p-n heterojunction elements, and photo-electric transducers such as solar batteries, photosensors, etc.
一种制备有机半导体的工艺,包括在具有纤维结构的乙炔高聚物中掺入特定的电子接受化合物。传统的电子接受化合物毒性很高,所提供的导电乙炔高聚物并不总是具有足够高的导电性,掺杂后机械强度严重下降,耐热性也不足。使用本发明的一种特定的低毒电子接受化合物,可以得到一种导电性乙炔高聚物,它具有更高的导电性、良好的柔韧性和耐热性。这种导电乙炔高聚物是一种 p 型半导体,可在 10-9 至 103Ω-1.cm-1 的范围内自由控制电导率,可用作导电材料、p-n 异质结元件和太阳能电池、光传感器等光电转换器的材料。
