  • 摘要

    采用半经验的Austin Model 1(AM1)方法,计算了-(PA)4-(PPP)m-(PA)4-共聚物的带电状态,该系列共聚物具有典型的阱垒阱结构特征.与中性态相比,带电态下其分子结构表现为C—C键长发生显著的改变.在不同的掺杂浓度及不同的势垒宽度下,电荷在势阱中的分布是不同的.

     

    Abstract

    We present the results of the Austin-Model 1 (AM1) geometry optimizations aimed at determining the charged geometry properties of -(PA)4-(PPP)m-(PA)4- triblock copolymers that have the well-barrier-well structure. The distributions of the doped charges depend upon the density of doped charges and the length of the barrier.
