摘要:

采用Mitsunobu 反应将杂环偶氮生色分子键入氟化聚酰亚胺母体制备新型的侧链含氟聚酰亚胺非线性光学(NLO)材料. 采用傅里叶变换红外(FT-IR)光谱、紫外-可见(UV-Vis)光谱、1H 核磁共振(1H NMR)谱和凝胶色谱(GPC)对材料进行表征. 热分析结果表明侧链型聚酰亚胺具有较高的玻璃化转变温度(Tg)(184-188 ℃), 热分解温度(Td)高达322 ℃. 采用简单全反射法于1550 nm处测定聚酰亚胺的电光系数(γ33), 含苯并噻唑偶氮苯胺的聚酰亚胺(PI1)具有较高的电光系数15 pm·V-1.

Abstract:

Hetarylazo chromophores were incorporated into fluorinated polyimide matrices to prepare novel nonlinear optical (NLO) side-chain fluorinated polyimides by the Mitsunobu reaction. Their structures were verified by Fourier transform infrared (FT-IR) spectra, UV-visible (UV-Vis) spectra, 1H nuclear magnetic resonance (1H NMR) spectra, and gel permeation chromatography (GPC). Thermal analysis results indicate that the side-chain polyimides have high glass transition temperatures (Tg) between 184 and 188℃ and thermal decomposition temperatures (Td) up to 322℃. The electro-optic coefficients (γ33) of the side-chain polyimides were measured by a simple reflection technique at 1550 nm. The fluorinated polyimide PI1 containing a benzothiazolylazoaniline chromophore possesses a high electro-optic coefficient of 15 pm·V-1.
