以Fe（tos）3为氧化剂，采用氧化原位聚合法合成了一种新型导电聚合物聚（3-甲氧基噻吩-2，5-二基-co-3，4-乙撑二氧噻吩-2，5-二基]/对甲苯磺酸酯（P1/tos）。通过紫外-可见光谱和光电子产额谱研究发现，与聚（3，4-乙撑二氧噻吩）（PEDOT）相比，P1具有更深的HOMO能级和更宽的能隙。P1/tos的电导率为10 S/cm，载流子迁移率约为0.6 cm 2/（V s），这是通过使用离子凝胶薄膜晶体管提取。计算出的载流子浓度为1020 cm-3，低于PEDOT/tos。P1/tos的Seebeck系数高于PEDOT/tos。
A novel conducting polymer, Poly(3-methoxythiophene-2,5-diyl-co-3,4-ethylenedioxythiophene-2,5-diyl]/tosylate (P1/tos), was synthesized by oxidative in situ polymerization using Fe(tos)3as an oxidant. Compared with poly(3,4-ethylenedioxythiophene) (PEDOT), P1 has a deeper HOMO level and a wider energy gap as observed by ultraviolet–visible spectroscopy and photoelectron yield spectroscopy. P1/tos showed electrical conductivity of 10 S/cm and a carrier mobility of about 0.6 cm2/(V s), which was extracted by using ion-gel thin film transistors. The calculated carrier concentration was on the order of 1020cm−3, which is lower than that of PEDOT/tos. The Seebeck coefficient of P1/tos was higher than that of PEDOT/tos.
