基于扩展的Su-Schrieffer-Heeger紧束缚模型,利用非绝热动力学方法研究了链内无序效应对共轭聚合物中极化子输运机制的影响.研究发现,极化子的输运由外加电场和链内无序效应共同作用的结果所决定.在一般情况下,链内无序效应不利于极化子的输运,但随着电场强度的增大,无序对极化子输运的影响减小. Based on the extended Su-Schrieffer-Heeger tight-binding model, the non-adiabatic kinetics method was used to investigate the effect of disorder in the chain on the transport mechanism of polaron in conjugated polymers. It was found that the transport of polaron The external electric field and the chaotic effect within the chain effect determined by the decision.Under normal circumstances, chain disorder effect is not conducive to the transport of polaron, but with the increase of the electric field strength, the disorder of the polaron transport The impact of transport is reduced.
