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。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 Uvvis 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.
