摘　　要：合成了一种大π共轭高分子———聚3 辛酰基吡咯(POPY)。利用1H NMR、FT IR和UV Vis对反应中间产物及目标产物POPY进行了结构表征。热重分析(TGA)表明,POPY可耐285℃的高温。通过真空I2掺杂处理,POPY的电导率提高了3个数量级,为0.023S/cm。采用标准后向简并四波混频(DFWM)系统对POPY的三阶非线性光学效应进行了研究。结果表明,在532nm处,POPY的三阶非线性极化率为9.2×10-10esu。光致发光(PL)研究表明,在360nm的紫外光的激发下,POPY能够发出很强的波长为414nm和437nm的蓝色荧光。A novel π-conjugated polymer, poly(3-octanoylpyrrole) (POPY) was synthesized firstly. The chemical structures of the intermediate and the POPY were characterized by 1H-NMR, FT-IR and UV-Vis spectroscopy. The thermal stability by thermogravimetric analysis (TGA) indicates that POPY decomposes at temperature of 285°C. The conductivity of POPY doped with iodine is 0.023 S/cm which is 3 order of magnitude higher than that of the intrinsic sample. The third-order nonlinear optical property of POPY was studied by the backward degenerate four wave mixing (DFWM) at 532 nm. The third-order nonlinear optical susceptibility of POPY is about 9.2×10-10 esu. The photoluminescence (PL) of POPY is also investigated. The result shows that POPY is a good photoluminescence material and strong blue fluorescence can be observed when the excitation wavelength is 360 nm.
