Single‐molecule devices, which are fabricated by the single molecule bridged through electrodes, provide a promising approach to investigate the intrinsic chemical or physical properties of individual molecules. Beyond the studies of single‐molecule wires, a large number of responsive single‐molecule junctions or devices with unique chemical or physical properties have been designed and fabricated by introducing the external field, which further offers the chance to explore conductive materials at the molecular level. Here, we summarized the latest studies on the behaviors of single‐molecule devices based on the photon, thermal, electric, or magnetic responses, and discussed the development of responsive single‐molecule devices in prospect.

迈向响应式单分子器件

由通过电极桥接的单分子制造的单分子设备为研究单个分子的固有化学或物理性质提供了一种有前途的方法。除了研究单分子导线外，还通过引入外部场来设计和制造了大量具有独特化学或物理特性的响应性单分子结或器件，这进一步为在分子水平上探索导电材料提供了机会。在这里，我们总结了基于光子，热，电或磁响应的单分子器件行为的最新研究，并讨论了响应型单分子器件的发展前景。
