聚醯亞胺(PI)在顯示器上的貢獻，倍受學界及產業界的注目，然此種電子材料仍有一些溶解度的問題需要克服。聚酯醯亞胺不僅改善了聚醯亞胺溶解度及加工性不佳的缺點，並且保有聚醯亞胺的熱穩定性佳等優點，是著名的高性能高分子材料。本論文使用直接聚縮合法及低溫溶液聚合法，將含有醯亞胺的單體及雙胺或雙醇合成聚酯醯亞胺，並將孤立發光團1,3,4-二唑及芴基導入，使溶解度有所提升。
芳香醯酮聚合物的結構由NMR及IR光譜分析，還有光學性質、溶解度、熱分析和X-ray分析其不同性質與討論結果。帶有發光旋環雙芴的聚酯醯亞胺衍生物具有相當高的玻璃轉換溫度和極佳的熱穩定度，兩種衍生聚合物以螢光放射光譜(PL)測定均放出藍綠光，放射出的最大值約400-600nm。含芴聚合物的電子親和力約2.75-2.84eV；氧化還原電位分析顯示具有可逆氧化及不可逆還原，也就是n-type光電材料。
使用介面聚合反應製備芳香醯酮類的液向型液晶聚合體，所有聚合物性質以NMR及IR光譜分析，還有光學性質、溶解度、熱分析和X-ray分析其不同性質與討論結果。由熱分析結果顯示這些共聚物具有良好的熱穩定性，熱重損失10%的溫度大約在348-370℃之間。

Polyimides (PI) have recently attracted attention of their potential use in display technology, and then intrigued interests in both academic and industrial circles. However, electronic materials have some solubility need further improvement. Poly (ester-imide)s are well known as high performance polymeric materials Those modified polyimides not only improve processability and solubility, but also exhibit excellent thermal stability. In this study, poly(ester-imide)s have preparated by direct polycondensation at low temperature in polymerization from imide-containing monomers and diol or diamine, and 1,3,4-oxadiazole and fluorene moieties by introducing into targeted molecules to promote solubility.
The structure of arylidenone polymer was confirmed by NMR and IR spectral analyses. The various characteristics of the resulting polymers including optical properties, solubility, thermal analysis, and X-ray diffraction analysis were determined and discussed. The luminescent poly(ester-imide)s derivatives based on spirobifluorene rings in the main chain showed relatively high glass-transition temperatures (about 160 °C) and good satisfactory thermal stability. Two polymers emitted blue-greenish light with photoluminescence (PL) emission maxima around 400–600 nm and the electron affinity of new polymers was estimated as 2.75–2.84 eV. Cyclic voltammetry displayed polymers had reversible oxidation and irreversible reduction, making them n-type electroluminescent materials.
The lyotropic LCPs of arylidenone polymer were prepared by interfacial polycondensation reaction. All these polyesters were confirmed by NMR and IR spectral analyses. The various characteristics of the resulting polymers including optical properties, solubility, thermal analysis, and X-ray diffraction analysis were determined and discussed. Thermogravimetric studies revealed that these polyesters have fairly good thermal stability, thermal degradation reactions were found 10% weight loss in the temperature range of 348-370℃。
