摘要: 在AM1半经验方法水平上,对不同数目的Li+位于C60笼内和笼外时形成的复合物进行几何优化,PAS负极材料由于掺杂C60而吸附更多的Li+,并且Li+容易嵌入到C60中,从理论上解释了聚并苯(PAS)导电性能改善的原因,并对PAS中掺杂C60的最佳比例进行了预测.

Abstract: According to semi-empirical method of AM1, the compounds which are located inside or outside C60 have been optimized. The results showed polyacenic semiconductor doped with C60 could absorb much more lithium ion, and lithium ions are easy to inset C60. The reason of improvement of polyacenic semiconductor conducting properties was analyzed theoretically, and the best doping proportion of C60 to polyacenic semiconductor was predicted.
