Paper Abstract

To manifest a photorefractive effect, the polymer must possess a photocharge generator, a charge transporter, a charge trapping center and a nonlinear optical chromophore. We have synthesized two types of novel photorefractive (PR) polymers. The type I PR polymers contain the NLO chromophore, the charge generator and the transporting compound covalently linked to the polymer backbone. The type II photorefractive polymers contain a conjugated backbone and a second order NLO chromophore. The design idea behind the structure of the type II polymers is the expectation that they will possess photorefractivity. Since the conjugated backbone absorbs photons in the visible region and is photoconductive, it is expected to play the triple roles of charge generator, charge transporter and backbone. Thus, the four functionalities necessary to manifest the PR effect will exist simultaneously in a single polymer.
