The doping of polymers with iodine (a strong electronic acceptor) for increasing their conductivity has been used in polyphenylene sulfide. The main drawback of this dopant is its diffusion, giving rise to instability in the electric conductivity. We found that the conductivity not only could be stabilized but also enhanced by the presence of some dyes which are known to form stable complexes with iodine. These finding with a particular emphasis on phthalocyanine are reported in this article.
