ABSTRACT:
Electrically conducting organic polymeric material having a preselected room temperature p-type electrical conductivity which may vary over the entire range characteristic of semiconductor behavior and into the range characteristic of metallic behavior, is prepared by controlled chemical doping of polyacetylene in the form of a polycrystalline film. Exceptionally high room temperature p-type electrical conductivity within the range of from about 0.1 to of the order of 10.sup.3 ohm.sup.-1 cm.sup.-1 is achieved with several electron acceptor dopants, including bromine, iodine, iodine chloride, iodine bromide and arsenic pentafluoride.
