摘要

本實驗共分兩部分：第一章以合成含1,2,4-三氮唑和三苯胺結構的聚醯亞胺；第二章以合成三氮唑為主鏈，側鏈分別含有咔唑與三苯胺之聚醚醯亞胺，並探討其熱性質、光學性質及應用。
　　合成的聚醯亞胺和聚醚醯亞胺皆具有良好的熱穩定性，氮氣環境下的熱裂解溫度（Td5）高於400℃，玻璃轉移溫度（Tg）範圍在250-350℃，其中以三苯胺為主鏈的聚合物，玻璃轉移溫度較1,2,4-三氮唑為主鏈的聚合物高。第一章以三苯胺為主鏈的聚合物比三氮唑為主鏈的聚合物有更佳的溶解性，而第二章的聚醚醯亞胺溶解度則因具有醚基而普遍較佳。紫外線可見光吸收光譜顯示吸收範圍皆受到推電子官能基的影響，以三苯胺為主鏈的吸收最大值與三氮唑為主鏈的吸收最大值皆在約280nm；以三苯胺為側鏈的螢光放射最大值約在400nm，卡唑為側鏈的則在約350nm。

This thesis consists of two parts. In Chapter 1, we synthesized novel polyimides containing 1,2,4-triazole and triphenylamine groups. In Chapter 2, we synthesized poly(ether imide)s in which main chain contains triazole group and side chain was carbazole group or triphenylamine group. The thermal properties, optical properties and solubility of the polymers were investigated and discussed.
　　The obtained polyimides and poly(ether imide)s all exhibited good thermal stability with 5% loss weight temperature higher than 400℃ in nitrogen, and the glass transition temperatures were about 250-300℃. The polyimides with triphenylamine group in the main chain had higher glass transition temperature and better solubility than the polyimides with triazole group in the main chain. The solubility with poly(ether imide)s were better than analogous polyimides. The UV-vis maxium absorption exhibited near 280nm for polymers with triphenylamine group in the main chain and polymers with triazole group in the main chain. The maxium photoluminescence emission near 400nm for polymers with triphenylamine group in the side chain and near 350nm for polymers with carbazole group in the side chain.
