Electrochemistry of polyacetylene, (CH) x : electrochemical doping of (CH) x films to the metallic state

Abstract

When silvery films of the semiconducting polymer, cis-‘polyacetylene,’(CH)_x, are used as the anode in the electrolysis of aqueous KI solutions or methylene chloride solutions of [Buⁿ ₄N]⁺[ClO₄]^–, films of (CHI_y)_x and [CH(ClO₄)_y]_x, respectively, are obtained which, for the compositions [CHI_0·07]_x and [CH(ClO₄)_0·0645]_x have high conductivities characteristic of the metallic state.
