Synthesis and Characterization of Poly{(3-Acetyl)Pyrrole-[2,5-Diyl(p-Butoxybenzylidene]}

合成了一种新型含有推-拉电子基团的聚吡咯衍生物——聚{(3-乙酰基)吡咯-[2,5-二(对丁氧基苯甲烯)]}(PA-PDBOBE)。通过红外光谱(FT-IR)、核磁共振(^(1)H-NMR)、紫外光谱(UV-Vis)、热重分析(TG)和循环伏安(CV)测试等分析手段对聚合物结构和性能进行了分析。UV-Vis谱表明,PAPDBOBE的光学禁带宽度(E_(g))为1.51 eV。该聚合物的TG谱显示聚合物的热分解温度为165℃。循环伏安特性曲线(CV)表明,该聚合物膜电极在LiClO_(4)乙腈溶液中-1 V~1 V的电压间有氧化还原反应,其氧化还原反应的峰电位分别为0.52 V和-0.51 V。

A polypyrrole derivative containing electron donor-acceptor groups(PAPDBOBE)was synthesised.The chemical structures and properties of the polymer were characterized by Fourier transform infrared spectrum(FT-IR),^(1)H nuclear magnetic resonance spectrum(^(1)H-NMR),UV-Vis,thermogravimetry(TG)and cyclic voltammetry(C-V)spectroscopy.UV-Vis spectroscopy reveals the energy bandgap of PAPDBOBE is 1.51 eV.TGA indicates that PAPDBOBE decomposes at 165℃.C-V of PAPDBOBE electrode in the potential range from-1V to 1 V is conducted in 0.1 mol LiClO_(4)/1L acetonitrile(AN)solution.The result shows that peak potentials of the redox reaction are 0.52 V and-0.51 V,respectively.
