The past two decades have witnessed increasingly rapid advances in the field of single-molecule electronics, which are expected to overcome the limitation of the miniaturization of silicon-based microdevices, thus promoting the development of device manufacturing technologies and characterization means. In addition to this, they can enable us to investigate the intrinsic properties of materials at the atomic- or molecular-length scale and probe new phenomena that are inaccessible in ensemble experiments. In this perspective, we start from a brief introduction on the manufacturing method of graphene–molecule–graphene single-molecule junctions (GMG-SMJs). Then, we make a description on the remarkable functions of GMG-SMJs, especially on the investigation of single-molecule charge transport and dynamics. Finally, we conclude by discussing the main challenges and future research directions of molecular electronics.

石墨烯-分子-石墨烯单分子结的制备及功能

在过去的二十年中，单分子电子学领域的发展日新月异，有望克服硅基微型器件小型化的局限性，从而促进了器件制造技术和表征手段的发展。除此之外，它们还使我们能够在原子或分子长度尺度上研究材料的固有特性，并探究集成实验中无法达到的新现象。从这个角度出发，我们从对石墨烯-分子-石墨烯单分子结（GMG-SMJs）的制造方法的简要介绍开始。然后，我们对GMG-SMJ的卓越功能进行了描述，尤其是对单分子电荷传输和动力学的研究。最后，
