Synthesis of Electrically-Conducting Organic Polymers:Halogen Derivatives of Polyacetylene, (CH)(X).

摘要

When silvery films of the semiconducting polymer, trans ;'polyacetylene', (CH)x, are exposed to chlorine, bromine or iodine vapor, uptake of halogen occurs, and the electrical 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 remarkable high conductivity at room temperature.
