本文利用新合成之二胺單體與二酸酐或二醯氯合成一系列新型含三苯胺之聚醯亞胺與聚醯胺。此二新型聚醯亞胺與聚醯安為非結晶型且可溶於許多有機溶劑如N,N-二甲基乙酰胺、N-甲基吡咯烷酮等。此兩種聚合物具有良好熱穩定性，其玻璃轉移溫度介於232-275度，10%熱烈解溫度超過500度。從循環伏安儀測得此兩種高分子膜塗佈於ITO玻璃具有兩個氧化還原電位分別介於 0.8-0.97V 及1.19-1.32V V。 此高分子薄膜展現電致變色特性，可從原本淡黃色變成綠色再變成藍色。
從循環伏安儀得知模型化合物M1 及M2 的氧化電位與其聚醯亞安及聚醯胺並不一致，可得知其氧化並非只從氮原子上所貢獻。在此，本論文結合理論計算觀點及實驗的結果，提出一種以分子軌道理論為基礎的氧化機構。

A series of novel triarylamine-containing aromatic polyimides and polyamides were synthesized by the novel diaimine monomer N,N,-bis(4-aminohenyl)-N΄,N΄-bis[4-(2-phenyl-2-isopropyl)phenyl]-1,4-phenylene- diamine to react with aromatic dianhydrides and diacid chlories respectively. All the polyimides and polyamides were amorphous and readily soluble in many organic solvents such as N,N-dimethylacetamide and N-methyl-2-pyrrolidone. They had useful levels of thermal stability associated with glass-transition temperatures 232-275 °C, 10% weight-loss temperatures in excess of 451 °C for polyamides and 500°C for polyimides in nitrogen. Cyclic voltammetry (CV) of these polymer films cast onto an indium-tin oxide (ITO)-coated glass substrate exhibited two reversible oxidation redox couples at potentials of 0.80-0.97 V and 1.19-1.32V, respectively, vs. Ag/Ag+ in acetonitrile solution. The polymer films revealed electrochromic characteristics, with a color change from pale yellowish neutral form to green and blue oxidized form.
The CV results of the model compound M1 and model M2, were not match to the oxidation peaks of polyimide and polyamide, indicating that the contribution of the oxidation was not only resulting from the electron removal of nitrogen atoms. Herein, from the combination of the experimental and computational study, we proposed an oxidation mechanism based on molecular orbital theory, which well explains the CV experimental result.
