【摘要】 利用非绝热动力学方法,理论上研究了一维导电共聚物[-(PT)x-(PPP)y]z-(PT)x-中的极化子在外电场作用下的动力学输运性质.研究发现,极化子在共聚物中不易传输,其运动敏感地依赖于嵌段间界面的耦合;嵌段尺度对于极化子的运动具有重要的影响.所得结果与相关实验一致.更多还原

【Abstract】 By using a nonadiabatic dynamical method,the dynamical transport properties of a polaron driven by external electric field in onedimensional conducting copolymer [(PT)x(PPP)y]z(PT)x was theoretically studied.It was found that it is difficult for a polaron to transport in the copolymer.The transport of a polaron is sensitively related to the interfacial coupling between the segments of the copolymer.The lengths of the segments markedly affect the motion of a polaron.The conclusions obtained in our study are consistent with the relative experiments result.更多还原
