摘要
从扩展的Ginder-Epstein模型出发,运用自洽迭代方法,研究了聚对苯亚胺中由环失配缺陷引起的环扭角孤子.一对缺陷结构互补电性相反的环扭角孤子光吸收的数值计算结果与PNB聚合物的光诱导吸收实验相符合.
Electronic structure of a pair of ringtorsion solitons, trapped by a ringmismatch, in the pernigranilinebase polymer is studied on the basis of the extended GinderEpstein model. Calulated absorption peaks of the pair of solitons are consistent with the lowenergy ones of the photoinduced absorption in the polymer.
