摘要
采用密度泛函理论B3LYP方法
在6-31G基组水平下
对聚噻吩未掺杂体系及其掺杂体系进行了计算
根据几何、前线轨道和原子电荷的计算结果
分析了掺杂剂与聚噻吩链上极子异构区的作用.修正了以前研究工作中不考虑掺杂剂
而认为聚噻吩链上的电子得失是完全的这一缺欠.
Abstract
The geometry structures of undoped
and Cl doped oligothiophene(containing 6 thiophene rings) are optimized using density functional theory(DFT) at the B3LYP/6-31G(d) level as implemented in GAUSSIAN 03 program.The interactions between the dopant Cl and the skeleton carbon atoms are analyzed according to the calculated results of geometries
frontier orbitals
and the atomic charges.This work reflects a real doped oligothiophene system
which reduces the limitation of neglecting the dopant by traditional treatm...
