ABSTRACT:
An electrically conductive organic polymeric material is disclosed which comprises (a) an insoluble and infusible substrate with a polyacene-type skeletal structure having a hydrogen/carbon atomic ratio of from 0.60 to 0.15, said substrate being a heat-treated product of an aromatic condensation polymer consisting of carbon, hydrogen and oxygen, and (b) an electron donating doping agent, or an electron accepting doping agent, or both; said material having a higher electrical conductivity than the undoped substrate (a). The electrically conductive organic polymeric material can be produced by a process which comprises heat-treating an aromatic condensation polymer consisting of carbon, hydrogen and oxygen in a non-oxidizing atmosphere by heating it to a temperature of 400.degree. to 800.degree. C. to form a substrate having a hydrogen/carbon atomic ratio of from 0.06 to 0.15, and then doping it with an electron donating doping agent, or an electron accepting doping agent, or a mixture of both, thereby making the electrical conductivity of the doped substrate higher than that of the substrate. The electrically conductive organic polymeric material exhibits excellent oxidation stability and has the electrical conductivity of a semiconductor or conductor.
