摘 要

3,4-二氧-羟甲基-乙基噻吩(EDOT-MeOH)是在3,4-亚乙基二氧噻吩(EDOT)的骨架上引入羟甲基,使EDOT导电率高、环境稳定性好、易成膜且透明性好等优点得以保留, 而羟甲基的引入使其导电性有了更大的提升。此外,分子中的羟基还可作为活性基团进一步与其他功能性分子进行组装,从而得到新的分子电子器件材料，可以克服EDOT的缺陷，例如其不溶不熔性等。从而具有广阔的诱人前景。本文所选择的羟甲基EDOT的合成路线分为三步反应。随后又对羟甲基EDOT的聚合反应进行了较为深入的研究，得到了较为理想的化合物。并对所得的聚羟甲基EDOT的性质进行了探究，得出了相应的结论。

Abstract

3, 4-2 oxygen - hydroxy methyl - ethyl thiophene (EDOT-MeOH) is in 3, 4 - thiophene and ethyl 2 oxygen (EDOT) on the skeleton of introducing hydroxymethyl, make the PEDT high electrical conductivity, environmental stability, easy film and retention of the advantages of good transparency, and the introduction of the hydroxymethyl its conductivity has larger ascension. In addition, the hydroxyl in molecules also can be used as active group and other functional molecular assembling, further to get new materials, molecular electronic device can overcome the defect of PEDT, such as its insoluble infusibility, etc. Which has a broad prospect of attractive. In this paper, the choice of hydroxymethyl EDOT synthetic route is divided into three steps reaction. Then the hydroxymethyl EDOT polymerization has carried on the thorough research, obtained the ideal compound. And the nature of the poly hydroxy methyl EDOT has carried on the exploration, the corresponding conclusions.

Keywords: 3,4- two oxygen - hydroxymethyl - ethyl thiophene process polymerization
