| Abstract: | Three chromophores with tricyanofuran and tricyanopyrroline electron acceptors were synthesized and doped in high glass transition temperature (T g) polymer poly(N-(4-acetoxylphenyl)maleimide-co-styrene, NAPMI-co-ST). The electro-optic (EO), optical, and thermal properties of the doped poly(NAPMI-co-ST) were characterized and discussed. After being corona poled under 12?kV, this high T g polymer material showed excellent EO activity and thermal stability. The highest EO coefficient (r 33) reached 48.2?pm?V?1 (1,310?nm) and could remain 90?% of the original value for 100?h at 85?°C. The EO coefficient was relatively higher compared with other high T g EO polymers. The thermal stability was also very good and the manufacture process was convenient and applicable for device fabrication. |
