Abstract: This invention relates to a process for producing an organic semiconductor. More specifically, it relates to a process for producing an electrically conductive acetylene high polymer, which comprises doping an acetylene high polymer having a fibrous microcrystalline (fibril) structure with a specified electron acceptor compound having low toxicity, to obtain an electrically conductive acetylene high polymer having an increased electrical conductivity, and flexibility and heat stability. The electrically conductive acetylene high polymer obtained by the process of this invention is a P-type semiconductor whose electrical conductivity can be freely controlled within the range of 10.sup.-9 to 10.sup.3 ohm.sup.-1, cm.sup.-1, and is useful as a material for photoelectric converter elements such as solar cells and photosensers, and as P-N hetero junction elements.
