Photorefractive Polymer with Side-Chain Second-Order Nonlinear Optical and Charge-Transporting Groups

Abstract

The authors report the synthesis and characterization of a new, low-T{sub g} polymer exhibiting the photorefractive effect. The photorefractive polymer contains a second-order nonlinear optical chromophore, a charge transporting group, and a long aliphatic chain covalently linked to the polymer backbone. A sensitizer (C{sub 60}) was molecularly doped into the polymer to facilitate photocharge generation. The photoconductivity, electrooptic (Pockels) effect, and photorefractive properties of the polymer are reported. 27 refs., 10 figs.
