Abstract
New methacrylate polymers containing the β-alkylpyridinium salt at the side chain were designed and synthesized in an attempt to enhance both the poling-induced second-order nonlinear optical susceptibility and its temporal stability. The corona poled polymer films showed a large second-order nonlinear optical susceptibility, χ(2)(-2a;ωω,ω). The larger χ(2) value of the homopolymer compared to that of the copolymer indicates that the concentration of the nonlinear optical chromophores in the copolymer is lower than the saturation value. The temporal stability of the poled structures seems better than that of some guest-host systems.
