A covalent bond between an individual pentacene molecule and a gold atom was formed by means of single-molecule chemistry inside a scanning tunneling microscope junction. The bond formation is reversible, and different structural isomers can be produced. The single-molecule synthesis was done on ultrathin insulating films that electronically isolated the reactants and products from their environment. Direct imaging of the orbital hybridization upon bond formation provides insight into the energetic shifts and occupation of the molecular resonances.
通过扫描隧道显微镜结内的单分子化学方法，在单个并五苯分子与金原子之间形成了共价键。键的形成是可逆的，并且可以产生不同的结构异构体。单分子合成是在超薄绝缘膜上进行的，该膜将反应物和产物与其环境进行电子隔离。键形成时轨道杂化的直接成像有助于深入了解分子共振的能量变化和占据情况。
