| 摘 要： | 利用3,4-乙撑二氧噻吩单体和对甲苯磺酸铁,分别以异丙醇、四氢呋喃和乙氰为溶剂,用化学氧化法合成了导电聚合物聚（3,4-乙撑二氧噻吩）,3种溶剂中的反应速率有较大差异,乙氰中反应速率最快,四氢呋喃中反应速率最慢.三者的聚合产物都具有较高的电导率,但四氢呋喃中合成产物的电导率略高于另外两个产物.红外光谱和拉曼光谱显示,3种溶剂中合成的聚（3,4-乙撑二氧噻吩）在化学结构、分子共轭长度、掺杂情况等方面基本相同.

| Abstract: | Poly(3,4-ethylenedioxythiophene) were chemically synthesized using EDOT monomer and Fe(OTs)_3 in three different solvents such as isopropanol,tetrahydrofuran and acetonitrile.There was a large difference in reaction rate in the three solvents at room temperature.EDOT in acetone keeps stable for less than 2h,but does not polymerize or does so very little after 10h in tetrahydrofuran.All of the products from above three systems have a high conductivity,but PEDOT prepared in tetrahydrofuran has a higher conductivity than the other two products.The results of Infrared and Raman spectrum indicated that the chemical structure,length of molecular conjugation and dopant degree of the three products were almost identical. |
