An ideal methodology for miniaturizing the physical size, enhancing the operational frequency, and building the multifunctional capability of functional chips is to use opto- or electroactive single molecules as their central elements; such devices are generally termed single-molecule electronics and optoelectronics. The exploration of the electronic and optoelectronic properties of materials at the single-molecule level also allows the complete elucidation of the correlation between molecular structure and function, which in turn aids technological advances that can help to address the challenge raised by Moore’s Law. In this Account, we present our ongoing investigative pursuits in the realm of single-molecule electronics and optoelectronics, with a particular emphasis on studies using graphene-molecule-graphene single-molecule junctions as the primary framework. To date, we have established a diverse range of single-molecule multifunctional devices, including photoswitches, field-effect transistors, rectifiers, light-emitting diodes, spin electronic devices, memristors, and molecular wires. These types of devices possess stable graphene electrodes and robust covalent molecule-electrode interfaces.

单分子功能芯片：充分发挥分子电子学和光电子学的潜力

缩小物理尺寸、提高工作频率和构建功能芯片多功能能力的理想方法是使用光或电活性单分子作为其中心元件；此类器件通常被称为单分子电子学和光电子学。在单分子水平上探索材料的电子和光电特性还可以完全阐明分子结构和功能之间的相关性，这反过来又有助于技术进步，从而有助于解决摩尔定律提出的挑战。在本报告中，我们介绍了我们在单分子电子学和光电子学领域正在进行的研究工作，特别强调使用石墨烯-分子-石墨烯单分子结作为主要框架的研究。迄今为止，我们已经建立了多种单分子多功能器件，包括光电开关、场效应晶体管、整流器、发光二极管、自旋电子器件、忆阻器和分子线。这些类型的设备拥有稳定的石墨烯电极和坚固的共价分子电极界面。
