构建由单个分子制成的电子元件是电子设备小型化和集成化的一种有前途的策略。然而，事实证明，在室温下实际实现用于信号传输和处理的分子器件和电路具有挑战性。在这里，我们展示了在 Cu(100) 表面上使用 SnCl2Pc 分子进行室温分子间信号传输和处理。分子的面内取向通过分子间相互作用有效耦合并作为信息载体。在耦合分子阵列中，信号可以沿着预先设计的路线在面内方向从一个分子转移到另一个分子，并进行处理以实现逻辑运算。这些现象使得能够使用显示内在双稳态的分子作为具有新功能的复杂分子器件和电路。
Building electronic components made of individual molecules is a promising strategy for the miniaturization and integration of electronic devices. However, the practical realization of molecular devices and circuits for signal transmission and processing at room temperature has proven challenging. Here, we present room-temperature intermolecular signal transfer and processing using SnCl2Pc molecules on a Cu(100) surface. The in-plane orientations of the molecules are effectively coupled via intermolecular interaction and serve as the information carrier. In the coupled molecular arrays, the signal can be transferred from one molecule to another in the in-plane direction along predesigned routes and processed to realize logical operations. These phenomena enable the use of molecules displaying intrinsic bistable states as complex molecular devices and circuits with novel functions.
