Single-molecule electronics, a pivotal branch of nanotechnology, focuses on the electrical properties of individual molecules, providing a theoretical foundation and technical support for the development of ultra-compact, energy-efficient electronic devices. Achieving precise control over electron transport in single-molecule junctions poses a significant technical challenge in this field. Electrochemical regulation, characterized by its exceptional tunability and reversibility, has emerged as a promising area of research within single-molecule electronics. This review highlights the progress made in the application of electrochemical control strategies over the past decade, encompassing the modulation of electron transport energy levels, molecular valence states, bonding mechanisms between electrodes and molecules, as well as the control of ionic liquid double-layer gating. By analyzing specific case studies, the aim is to enhance students’ understanding of the forefront of single-molecule electronics and its critical importance in contemporary nanoelectronics.
