C60-P-苯并咪唑衍生物分子结构和电子光谱的理论研究
Theoretical study on the electronic structure and geometry of the derivatives of benzimidazole-C60-P
【摘要】 用半经验AM 1法研究了C60-P-苯并咪唑衍生物的分子轨道、电荷分布和几何构型.计算结果显示:分子(1)具有较低的跃迁能,LUM O轨道分布在C60上,电荷从取代基向C60转移.预测(1)可能在基态下产生长寿命的电荷分离态.
【Abstract】 The structure and electronic properties of the derivertives of benzimidazole-C60-P have been studied by using AM1 method.The results calculated indicated that the compound(1) have a lower energy difference between HOMO and LUMO.It was found that the electron cloud on unoccupied frontier mainly came from the contribution C60.A long lived charge-separated state may occur in the objective compound(1).
