测量了含杂环基团的三苯胺衍生物掺杂聚合物的空穴漂移迁移率，研究了三苯胺衍生物分子轨道分布对电荷输运性质的影响。用Bässler等人提出的无序理论分析了两种三苯胺衍生物掺杂聚合物的迁移率随温度的变化关系。Bässler，Phys. Status Solidi B 175（1993）15.]并且发现三苯胺衍生物的最高占据分子轨道（HOMO）分布对对角和非对角无序的影响很小，但对该形式体系中的无无序迁移率有很大的影响。
The hole drift mobilities of polymers doped with triphenylamine derivatives including heterocyclic groups have been measured and the effect of molecular orbital distributions of triphenylamine derivatives on the charge transport properties has been studied. The temperature dependence of the mobilities of polymers doped with two kinds of triphenylamine derivatives has been analyzed using the disorder formalism presented by Bässler and co-workers[H. Bässler, Phys. Status Solidi B 175(1993) 15.] and it has been found that highest occupied molecular orbital (HOMO) distribution of the triphenylamine derivatives has little effect on the diagonal and off-diagonal disorder but has a large effect on the disorder-free mobility in this formalism.
