Abstract

Can a photosensitizer enhance the photoconductivity of PPV (poly(p-phenylenevinylene))? The use of a palladium-catalyzed coupling reaction is described for the production of a series of PPV derivatives that contain different amounts of a bis(terpyridine) ruthenium(II) metal complex, a well-known photosensitizer when covalently linked to electron donating and accepting groups. Results of optical and electrical investigations are presented that indicate that the opening question can be answered in the affirmative.
