摘要: 以成膜性能优异、主链上含有多个羟基的聚双酚A二缩水甘油醚-苯胺(BPAN)为骨架,将二阶非线性光学活性发色团分子以键合形式挂接到聚合物主链上,形成新型侧链型聚合物.此聚合物保留了原聚合物体系成膜性好和可进一步交联等优点.极化过程中以含有异氰酸酯基的同种发色团分子作为交联剂,得到发色团含量进一步提高的交联型极化聚合物.采用衰减全反射法(ATR)测得体系的电光系数(r33)为6.7 pm/V(1315 nm).

Abstract: A novel NLO side-chain polymer was synthesized by attaching the NLO chromophore to a hydroxy-containing polymer BPAN which possesses excellent processability.The new polymer inherited the good performance of BPAN such as good film formation property and cross-linkability,etc.Cross-linked poled polymer with even higher content of NLO chromophore was obtained by taking the same kind of NCO-containing chromophore as cross-linking agent.The electro-optic coefficient of the poled polymer was 6.7 pm/V,which was measured by ATR method at 1315 nm.

Key words: poled polymer, cross-linking, NLO, EO, Attenuated Total Reflection(ATR)
