摘要

本實驗合成三種新型含1,2,4-triazole之二氟單體，分別具有carbazole、triphenylamine、azobenzene的結構，再與各種二醇類化合物在添加碳酸鉀的極性非質子溶劑1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)- pyrimidinone(DMPU)中聚合出聚芳香醚。
這些單體與高分子以元素分析(EA) 、FT-IR以及NMR鑑定其結構。UV-Vis及photoluminescence(PL)光譜分析其光學性質；高分子溶於THF時，UV-Vis吸收範圍在240∼380nm, PL光譜顯示其波峰波長在320∼520nm。
以TGA 和DSC測定其熱性質,這些高分子經由DSC熱分析儀器結果顯示其玻璃轉移溫度Tg約在185 ℃以上。經由動態熱重量分析(TGA)結果顯示，它在氮氣中的5%重量損失溫度約在316 ℃以上。

We synthesized three 1,2,4-triazole based difluoro monomers containing azobenzene, carbazole, and triphenylamine, and azobenzene, respectively. The monomers were polymerized with various diols in polar aprotic solvent, 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (DMPU), in the presence of potassium carbonate yielding novel poly(aryl ether)s.
The structures of monomers and polymers were confirmed by Elemental analyzer(EA), FT-IR and NMR. The optical properties were analyzed by UV-Vis and photoluminescence(PL) spectroscopy. The polymers exhibited UV-Vis absorption bands at 240-380nm in THF solution. Their photoluminescence spectra showed emission peaks around 320-520 nm in THF solution.
The thermal properties of polymers were evaluated by TGA and DSC. The polymers exhibited glass-transition temperatures above 185 ℃, and the temperatures at 5% weight loss above 316 ℃ in nitrogen.
