合成了一种新型含有推-拉电子基团、可溶性的聚吡咯衍生物-聚{（3-乙酰基）吡咯-[2,5-二（对辛氧基苯甲烯）]}（PAPDOOBE）。并通过FT-IR、1 H NMR、UV-Vis、TG和CV等分析手段对聚合物结构和性能进行了分析。UV-Vis谱表明PAPDOOBE的光学禁带宽度（Eg）为1.44eV。循环伏安特性曲线（C-V）表明,该聚合物膜电极在0.1mol/L LiClO4的乙腈溶液中、-1～1V的电压间存在氧化还原反应;在100mV/s的扫描速率下,其氧化还原反应的峰电位分别为-0.21和-0.53V。该聚合物的TG谱显示聚合物的热分解温度为168℃。
A novel soluble polypyrrole derivative containing electron donor-acceptor groups（PAPDOOBE） was synthesised.The chemical structures and properties of the polymer were characterized by FT-IR,1H NMR,UV-Vis,TG and C-V spectroscopy.UV-Vis spectroscopy revealed the energy bandgap of PAPDOOBE is 1.44eV.Cyclic voltammetry（CV） of PAPDOOBE electrode in the potential range from-1 to 1V was conducted in 0.1mol LiClO4/1L acetonitrile（AN） solution.The result showed that peak potentials of the redox reaction were-0.21 and-0.53V,respectively.TGA indicates that PAPDOOBE decomposes at 168℃.
