Single molecules are sent and received accurately over long distances across a surface Ever since the 2016 Nobel Prize in Chemistry was awarded “for the design and synthesis of molecular machines,” growing attention has been aimed at connecting and embedding molecular machines into hierarchically more complex systems for sophisticated applications. Such connections would, for example, enable the targeted delivery of molecules over larger distances. An important question that arises in this context is what kind of transporter would do such a job, over what distances, and with what degree of precision. On page 957 of this issue, Civita et al. (1) found a distinct example of a bromine-terminated terfluorene molecule on a metal surface that can be sent and received deliberately across more than a hundred nanometers with atomic precision.

保持正轨的分子旅行车

单个分子在表面上长距离准确发送和接收自从 2016 年诺贝尔化学奖被授予“分子机器的设计和合成”以来，越来越多的关注旨在将分子机器连接和嵌入到分层更复杂的系统中用于复杂的应用。例如，这种连接可以实现分子在更远距离上的靶向传递。在这种情况下出现的一个重要问题是，什么样的运输工具可以完成这样的工作，传输距离是多少，精度是多少。在本期第 957 页，Civita 等人。(1) 在金属表面上发现了一个溴封端的三芴分子的独特例子，它可以在一百多个纳米范围内以原子精度故意发送和接收。
