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.

构建由单个分子组成的电子组件是使电子设备小型化和集成化的一种有前途的策略。然而，事实证明在室温下用于信号传输和处理的分子装置和电路的实际实现具有挑战性。在这里，我们介绍了室温下分子间信号的传输和使用SnCl _2的处理Cu（100）表面上的Pc分子。分子的面内取向通过分子间相互作用而有效地偶联，并用作信息载体。在耦合的分子阵列中，信号可以沿着预先设计的路径沿平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。这些现象使具有固有双稳态的分子能够用作具有新颖功能的复杂分子装置和电路。
