A novel conducting polyacetylene derivative

Abstract

Doping of predominantly cis polyacetylene with FSO₂OOSO₂F in SO₂F₂ solutions at low temperatures yields materials that possess apparently metallic electrical conductivities with, for example, σ_RT= 700 Ω^–1 cm^–1, increasing to a maximum of 800 Ω^–1 cm^–1 at 150 K before declining to 640 Ω^–1 cm^–1 at 4·2 K.
