Abstract

The electronic and spatial structure of 3,4-ethylenedioxythiophene oligomer containing 12 units (E12) in 0, +1, +2, +3, and +4 charge states has been calculated by the method of density functional theory (B3LYP 6-31 G**). It is shown that electron conductivity in the oxidized oligomer E12⁴⁺ is provided by two bipolarons at the ends of the chain.

3,4-乙烯二氧噻吩低聚物的极化子态

采用密度泛函理论(B3LYP 6-31 G**)计算了含12个单元的3,4-乙烯二氧噻吩低聚物(E12)在0、+1、+2、+3和+4电荷态的电子结构和空间结构。结果表明，氧化低聚物E124+的电子导电性是由链两端的两个双极化子提供的。
