合成了一种新型酰基取代的聚吡咯衍生物—聚（3-戊酰基）吡咯（PVPy）。通过傅立叶变换红外光谱（FT-IR）、氢核磁共振谱（1H-NMR）、紫外-可见光谱（UV-Vis）、热重分析（TGA）和荧光光谱（PL）等分析手段对聚合物的结构和性能进行了分析。PVPy的TGA谱显示,该聚合物的热分解温度为222℃;通过碘掺杂和浓硫酸（98%）掺杂处理后,PVPy的电导率提高了3个数量级,分别为0.52 S/cm和0.28 S/cm;UV-Vis谱表明;PVPy的光学禁带宽度（Eg）为2.16 eV;PL研究表明,在346 nm的紫外光的激发下,PVPy能够发出很强的波长为423 nm的蓝色荧光。
A polypyrrole derivative,poly（3-valeroylpyrrole）（PVPy） with acyl substituents was synthesised.The chemical structure and properties of the polymer were characterized by Fourier transform infrared spectroscopy（FT-IR）,1H-nuclear magnetic resonance（1H-NMR）,ultraviolet-visible spectroscopy（UV-Vis）,thermal gravimetric analysis（TGA） and photoluminescence spectroscopy（PL）.TGA results indicate that PVPy is decomposed at 222 ℃.The conductivities of PVPy doped with iodine and concentrated sulfuric acid（98%） are 0.52 S/cm and 0.28 S/cm,respectively.UV-Vis reveals the energy band gap of PVPy is 2.16 eV.The PL of PVPy was also investigated,the result shows that PVPy is a good photoluminescence material and strong blue fluorescence can be observed when the excitation wavelength is 346 nm.
