Uniaxially oriented film of an insoluble conducting polymer, poly(p-phenylene) (PPP) was prepared. At first, the aligned molecular strands of PPP were prepared by friction-transfer technique. Then homoepitaxially grown PPP film was formed on it by the polymerization of benzene. The film exhibits anisotropic optical and electrical properties. When it was doped with SbF₅, the oriented film shows the remarkable anisotropic conductivity. The conductivity along the friction-transferred direction as the origin of structure was measured to be thousand times higher than that in the perpendicular direction.
