We report on the synthesis of conjugated polymer (CV-QP) containing carbazole (donor) and quinoline (acceptor) using Wittig methodology. The structural, optical and thermal properties of the polymer were investigated by FT-IR, NMR, GPC, UV, PL, cyclic voltammetry, atomic force microscopy (AFM) and thermogravimetric analysis (TGA). The polymer exhibits thermal stability upto 200 °C and shows good solubility
我们报告使用Wittig方法合成包含咔唑(供体)和喹啉(受体)的共轭聚合物(CV-QP)。通过FT-IR,NMR,GPC,UV,PL,循环伏安法,原子力显微镜(AFM)和热重分析(TGA)研究了聚合物的结构,光学和热性能。该聚合物在高达200°C的温度下显示出热稳定性,并在常见的有机溶剂中显示出良好的溶解性。该聚合物在360nm的薄膜中具有光吸收带,并在473nm处形成发射带。由起始吸收边缘计算出的光能带隙为2.69eV。通过使用DMA(电子给体)和DMTP(电子受体)发现了聚合物CV-QP的荧光猝灭。AFM图像表明观察到三角形颗粒,并且发现粒径为1.1μm。
