本研究先合成4’-N,N-Bis(2-hydroxyethylene)-N-(propyl)amine-4-nitroazobenzene發色團單體，接著合成兩種亞醯胺酸BTI與含氟的6FTI後利用羧酸基與發色團單體上醇基進行聚酯反應合成四種不同含氟比例聚亞醯胺酯。所合成之單體與高分子以FT-IR、NMR與UV光譜鑑定其結構，以GPC測定高分子分子量分布，以DSC、TGA鑑定熱力性質。再利用反射法測量高分子電光係數(EO)，用UV觀察吸收度極化後的安定性的情形，並觀察溫度對電光係數的影響，最後觀察增加含氟鏈段對高分子與溶劑溶解度的影響。
結果發現加入含氟鏈段可以增進高分子玻璃轉移溫度(Tg)、並得到較高的電光係數和極化後的穩定度，並明顯改善對一般質子溶劑的溶解度。

關鍵字：非線性光學、含氟聚亞醯胺酯

In this research,first we synthesized chromophore monomer which contain hydroxy group、two kind imide acid(BTI and 6FTI with flurocarbon). The four kinds of different ratio poly-imide-ester with flurocarbon were prepared from hydroxy group of chromophore monomer and acid group of imide acid. All the monomers and poly-imide-ester were characterized by using FT-IR、NMR and Uv-vis；using GPC to measure distribution of polymer molecular weight；using TGA and DSC to identify the thermal properties. Then we used reflectional method to measure EO coefficient and observed the degree of absorption changing after poling. Finally we observed the influence of temperature to EO coefficient and the flurocarbon influence the degree of dissoluation.
The result show that add flurocarbon to poly-imide-ester can promote Tg and get good higher EO coefficient. And also get better stabilization and the good degree of dissolution for general protonal solvent.
