Synthesis of electrically conducting organic polymers: halogen derivatives of polyacetylene, (CH)x
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 markedlyExpand
