Abstract

Polyacetylene, (CH)_X, has been oxidized (doped) by CuCl₂ to give highly conducting charge-transfer complexes. Conductivities of highly doped films range from 30 to 80 Scm⁻¹ corresponding to y = 0.06 – 0.12. In lightly doped samples a rapid decrease in the activation energy of conduction is observed with increasing dopant concentration as well as the appearence of the typical dopant-associated IR-absorptions. Doping is believed to proceed via a partial reduction of CuCl₂ and the insertion of stabilizing anions such as CuCl⁻ ₃.
