A new charge transporting polymer for photorefractive applications

Summary form only given. Since the first observation of photorefractivity in a polymer, there has been continued interest in these polymers for applications including data storage, phase conjugation, pattern recognition, imaging through turbid media, laser-based-ultrasound detection, image amplification and novelty filtering. Although many materials published show promising performance, there is still a great need for improved materials. We present a novel hole transport polymer the combines the hole transporter tri-benzyl amine with the polysiloxane backbone, abbreviated as PSX-TBA. Methoxy substituents were added to improve compatibility with polar chromophore dopants.
