摘　　要：以2,5-二溴-3-己基噻吩和2,5-二溴吡啶为原料,采用格氏试剂法合成了3-己基噻吩-co-吡啶共聚物(P3HT-co-PY)。产物的结构通过对红外光谱(FT-IR)以及核磁共振谱(1H-NMR)的分析来表征确定,并且对合成温度、时间、催化剂用量进行了研究,结果显示在50℃,催化剂用量为0.8%eq mol下反应8 h时的聚合产率最高,达到34%。3- hexylthiophene- co- pyridine（ P3HT- co- PY） was synthesized via GRIM from the materials of 2,5- dibromine- 3- hexylthiophene and 2,5- dibromopyridine. The structure of the product was analyzed using Infrared Spectroscopy（ FT- IR） and Nuclear Magnetic Resonance Spectroscopy（^1H- NMR）. The optimum polymerization condition which was determined by plenty of accurate experiments reached the highest yield at 34% with the conditions as follows： polymerize of 50 ℃,length of 8 h,0. 8% eq mol dosage of the given catalyst.
