| 摘 要： | 采用Fe(III)催化剂合成法合成聚3-丁基噻吩(P3BT)、聚3-己基噻吩(P3HT)和聚3-十二烷基噻吩(P3DDT)。用GPC和1 H-NMR对所合成的聚合物的相对分子质量和结构进行表征,用SEM对所合成的聚合物的表面形貌进行观察,并用紫外-可见吸收光谱和荧光光谱研究3种聚合物氯仿溶液的光学性能。结果表明,用该方法合成的聚合物以非晶态形式存在;具有较高的相对分子质量;在氯仿溶液中,P3BT、P3HT、P3DDT的最大吸收峰分别为:436nm、437nm和430nm,最大发射峰分别为570.0nm、581.2nm和573.8nm。综合分析发现P3HT更适于用做聚合物太阳能电池材料。

| Abstract: | P3BT,P3HT and P3DDT were synthesized by the method of Fe(III)catalyst.Their chemical structures and relative molecular mass were characterized by gelpermeation chromatography(GPC)and 1H-NMR.Their surface morphology were observed by SEM,the results showed that they were amorphous.The absorption,fluorescence properties of them in chloroform solutions were studied.The maximum Uv-vis wavelength of P3BT,P3HT and P3DDT in chloroform solutions were 436nm,437nm and 430nm,respectively,and their corresponding emitted wavelengths were 570.0nm,581.2nm and 573.8nm,respectively. |
