Titel
Nonlinear optical side-chain polymer with high thermal stability and its pyroelectric thermal analysis
Abstract
Stable polymers with nonlinear optical side groups were synthesized from maleic anhydride copolymers and the azo dye Disperse Red 1 via esterification. After electrode poling under 135 V/ mu m at 185 degrees C, thermal stabilities were measured by pyroelectric and electro-optic thermal analysis and compared to a guest/host polymer of polymethylmethacrylate and the same dye. The pyroelectrically detected dipole orientation and the electro-optic activity of the side-chain polymers decreased only above 150 degrees C, and electro-optic r33 coefficients of up to 6 pm/V were achieved at 780 nm even without optimizing the dye content.
