Notes:
Electropolymerization of cyanogen in acetonitrile containing an electrolyte yields a poly(cyanogen). Its structure involves an open-structured dimer derived from the heterocyclic anion C7N7- mixed with a sequence of nitrile-substituted, conjugated carbon-nitrogen bonds. Although this polymer is an insulating solid, pyrolysis in vacuo to 700°C leads to highly conducting carbon-nitrogen pyropolymers via crosslinking and nitrogen elimination. The 700° pyropolymer has a carbon-nitrogen ratio of 5:1, a room temperature conductivity of 1 Ω-1 cm-1, and an activation energy for conduction of ∼0.03 eV.
