The PNP structure realized by energy band engineering is widely used in various electronic and optoelectronic devices. In this work, we succeed in constructing a PNP-type single-molecule junction and explore the intrinsic characteristics of the PNP structure at the single-molecule level. A back-to-back azulene molecule is designed with opposite ∼1.7 D dipole moments to create PNP-type single-molecule junctions. In combination with theoretical and experimental studies, it is found that the intrinsic dipole can effectively adjust single-molecule charge transport and the corresponding potential barriers. This energy band control and charge transport regulation at the single-molecule level improve deep understanding of molecular charge transport mechanisms and provide important insights into the development of high-performance functional molecular nanocircuits toward practical applications.

通过 PNP 型单分子结的偶极子调制电荷传输

通过能带工程实现的PNP结构广泛应用于各种电子和光电器件中。在这项工作中，我们成功地构建了 PNP 型单分子结，并在单分子水平上探索了 PNP 结构的内在特征。一个背靠背的甘蓝分子被设计成具有相反的 ∼1.7 D 偶极矩，以创建 PNP 型单分子连接。结合理论和实验研究，发现本征偶极子可以有效调节单分子电荷传输和相应的势垒。
