摘　　要：共轭聚合物半导体由于其复杂的微观结构表现出不同程度的无序度,这使得人们对共轭聚合物中电荷输运的理解产生很大困惑。为了清晰认识无序对电荷输运的影响,文中讨论了几种主要的共轭聚合物分子结构和载流子输运模型,深入阐述了无序产生的原因及其影响,揭示了无序如何决定有机半导体中的电荷输运,从而为开发高性能的半导体聚合物及电子器件提供更多思路。Conjugated polymer semiconductors exhibit diverse degrees of disorder due to their complex microstructures,which leads to confusion on the understanding of charge transport.In order to elucidate the effect of disorder on charge transport,several common molecular structures and the relevant carrier transport models are reviewed,where the causes and effects of disorder are discussed in detail.This paper provides insight into how disorder determines charge transport in organic semiconductors,and thus offers some ideas in developing high⁃performance semiconductor polymers for electronic devices.
