Conjugated polymers which are different from traditional semiconductor, have some unique properties. Most of them are quasi-one-dimensional systems with strong electron-phonon interaction. Their carriers are composite particles, which are different from simply electron and hole, characterized with the surrounding distortion of lattice configuration (polaron with spin 1/ 2 , bipolaron with spin 0 etc.). The transport of the carriers and the process that oppositely charged polarons combine to from exciton are believed to be of fundamental importance for electroluminescence properties.

共轭聚合物具有不同于传统半导体的特性，它们是强电-声相互作用的准一维体系，其载流子不再是简单的电子和空穴，而是伴随晶格畸变的具有内部结构的复合粒子(自旋1/2的极化子、自旋为0的双极化子等)，这些载流子的输运、以及正负极化子对复合成激子的过程在很大程度上决定着聚合物的电致发光性质。

We find that the scattering process of the charge and lattice defect is different under different strengths of electric field and the interchain coupling interactions.(1) The results of the dynamics of oppositely charged polarons in polymer chains show that:①At a weak field (.1 mV/A), they finally scatter into an entity, which will be dissociated as a pair of neutral solitons after their first collision and separation.

1聚合物中极化子对的非弹性散射对电场强度的依赖关系表明：在弱场(小于0.1mV/A)时，电荷由于量子隧穿相互抵消，但不改变符号，极化子晶格碰撞后带着剩余的电荷返回，但是它们不能分得很远，在电场作用下，可进行第二次碰撞，结合成一个整体，然后又分成一对中性的孤子对。

In the"strong"electron-phonon coupling limit,the ampli-tude of the frozen-in lattice distortions caused by strong Jahn-Tellercouplingis found to be large enough to localize the itinerant electrons as polarons leading tothe thermally activated conduction behavior above Tc.
