Abstract

Poly(3-octylthiophene) was irradiated with X-rays in atmospheres of CH₃Br, SF₆, and N₂O gases. The electrical conductivity was increased after the irradiations. The electrical conductivity was also increased by irradiating the gases near the polymer film without irradiating the film itself. This result indicates that dopants were generated upon irradiation in the gas phase and the polymer was doped through reactions of the dopants with the polymer. The radiation-induced doping effects were also observed for poly(3-octylthiophene) coated with solid 1,2,5,6,9,10-hexabromocyclododecane.
