Notes:
Three new polymers, poly(m-iodophenylacetylene), poly(p-iodophenylacetylene) and poly[p(trilsopropylsilylethynyl)phenylacetylene], were prepared and their photoelectrical properties were studied. The experimental results suggest that the photogeneration of charge carriers in these polymers proceeds via the creation of Intermediate Coulomb force bound charge pairs and their subsequent dissociation in the external electric field by the Onsager mechanism. The electron-withdrawing and electron-donating groups attached to the phenyl ring were found to influence the photogeneration process substantially.
