Modern electronic devices perform their defined action because of the complete reliability of their individual active components (transistors, switches, diodes, and so forth). For instance, to encode basic computer units (bits) an electrical switch can be used. The reliability of the switch ensures that the desired outcome (the component’s final state, 0 or 1) can be selected with certainty. No practical data storage device would otherwise exist. This reliability criterion will necessarily need to hold true for future molecular electronics to have the opportunity to emerge as a viable miniaturization alternative to our current silicon-based technology. Molecular electronics target the use of single-molecules to perform the actions of individual electronic components. On-demand final state control over a bistable unimolecular component has therefore been one of the main challenges in the past decade(1−5) but has yet to be achieved. In this Letter, we demonstrate how control of the final state of a surface-supported bistable single molecule switch can be realized. On the basis of the observations and deductions presented here, we further suggest an alternative strategy to achieve final state control in unimolecular bistable switches.

表面绑定双稳态单分子开关的按需最终状态控制

现代电子设备由于其各个有源组件(晶体管,开关,二极管等)的完全可靠性而执行其定义的动作。例如,为了对基本计算机单元(位)进行编码,可以使用电气开关。开关的可靠性确保可以确定地选择所需的结果(组件的最终状态,0或1)。否则将不存在实用的数据存储设备。对于未来的分子电子学来说,必须具有这种可靠性标准,才有机会成为我们当前基于硅的技术的可行的小型化替代方案。分子电子学的目标是使用单分子来执行单个电子组件的作用。因此,在过去十年中(1-5),对双稳态单分子组分的按需最终状态控制已成为主要挑战之一,但尚未实现。在这封信中,我们演示了如何实现对表面支撑的双稳态单分子开关的最终状态的控制。根据此处介绍的观察和推论,我们进一步建议一种在单分子双稳态开关中实现最终状态控制的替代策略。
