matching between the HOMO levels of C(60) and oPPVs emerged as a key parameter for supporting molecular-wire-like behavior: It favors rapid and efficient electron or hole injection into the oPPV wires. Large electronic coupling values were determined as a result of paraconjugation in the oPPV moieties.

乙烯基低聚物(oPPV)连接到光激发态电子供体(即
四苯基卟啉锌)和电子受体(即C(60)),被设计,合成和测试为电子传输模型系统。详细的理化研究主要集中在长距离电荷分离,电荷
重组和动力学上,发现衰减因子β为0.03 +/- 0.005 A(-1)。C(60)和oPPVs的HOMO能级之间的能量匹配成为支持分子线状行为的关键参数:它有利于快速有效地将电子或空穴注入oPPV线中。由于oPPV部分的共轭作用,确定了较大的电子耦合值。
