Polyarylene (poly-p-phenylene, poly-1, 5-naphthylene, poly-2, 7-naphthylen) were prepared by nickel-catalyzed polycondensation of Grignard reagents from the corresponding dibromides. The polymers were extracted monomer on Soxhlet'sextractor, then these were annealed at 400°C for 24h in vacuo. The polymer were doping in order to increase conducting.
