Abstract
Abstract Doped acetylene polymers are produced by immersing an acetylene polymer under an inert gas atmosphere in an organic solvent solution of a dopant selected from the group consisting of a platinum group metal complex, a carbonium salt, an oxonium salt and a parabenzoquinone derivative. According to this process, a doped acetylene polymer having any desired electrical conductivity can be produced and the doped acetylene polymer thus obtained has excellent properties as an organic semiconductor material for solar batteries, various sensors, etc.
