TLDR
When silvery films of the semiconducting polymer, trans polyacetylene, (CH)x, are exposed to chlorine, bromine, or iodine vapour, uptake of halogen occurs, and the conductivity increases markedly (over seven orders of magnitude in the case of iodine) to give silvery or silvery-black films, some of which have a remarkably high conductivity at room temperature.Abstract:
When silvery films of the semiconducting polymer, trans‘polyacetylene’, (CH)x, are exposed to chlorine, bromine, or iodine vapour, uptake of halogen occurs, and the conductivity increases markedly (over seven orders of magnitude in the case of iodine) to give, depending on the extent of halogenation, silvery or silvery-black films, some of which have a remarkably high conductivity at room temperature.read more

The chemical nature of polyacetylene doping
T. C. Clarke,G. B. Street +1 more
TL;DR: The chemical mechanisms involved in oxidative doping of polyacetylene, (CH) x, have been investigated using a variety of spectroscopic techniques as mentioned in this paper, including electron transfer from the polymer to the dopant to give a polyolefinic cation and a reduced form of the reduction which intercalates between the polymer chains.
