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.enelectro-optical effectsnonlinear opticsoptical polymerspyroelectricitythermal analysissynthesisside-chain polymerthermal stabilitypyroelectric thermal analysisnonlinear optical side groupsmaleic anhydride copolymersazo dyedisperse red 1esterificationelectrode polingelectro-optic thermal analysisguest/host polymerdipole orientation185 degc150 degc780 nm621journal article
