为了构造复杂的分子和分子装置,微小的、原子大小的物体必须以一种精确的方式聚集在一起并连接起来。不管是好是坏,这项艰巨的任务仍然是以一种方式完成的,就像把乐高积木放进洗衣机里,然后希望成千上万的分子以某种方式最终组装成想要的产品,要么是完全偶然的,要么是在其他分子大小的物体的指导下。催化剂。在这期杂志的第298页,Albrechtet等人展示了如何根据扫描隧道显微镜(STM)尖端的电压脉冲将单个分子转化为三种不同的产物。值得注意的是,这三种产品可以在高度控制下反复相互转换。
To construct complex molecules and molecular devices, tiny, atomic-sized objects must be brought together and connected in a precise way. For better or for worse, this daunting task is still mostly done in a manner likened to putting Lego blocks in a washing machine and hoping that the quintillions of molecules somehow end up assembling themselves into the desired product, either by complete chance or under the guidance of other molecular-sized objects—i.e., catalysts. On page 298 of this issue, Albrechtet al.show how a single molecule can be transformed into three distinct products depending on the voltage pulses from the tip of a scanning tunneling microscope (STM). Notably, the three products can be repeatedly interconverted with a high degree of control.
