A novel approach to constructing tunable and robust 2D binary molecular nanostructures on an inert graphite surface is presented. The guest molecules are embedded into a host molecular matrix and constrained via the formation of multiple intermolecular hydrogen bonds. By varying the binary molecular ratio and the molecular geometry, various molecular arrays with tunable intermolecular distances are fabricated. The results suggest a promising route for the fabrication of ordered and stable molecular nanostructure arrays for molecular sensors, molecular spintronic devices, and molecular p-n nanojunctions.
提出了一种在惰性石墨表面构建可调谐和稳健的二维二元分子纳米结构的新方法。客体分子被嵌入到主体分子基质中，并通过形成多个分子间氢键来约束。通过改变二元分子比和分子几何形状，可以制备具有可调分子间距离的各种分子阵列。研究结果为用于分子传感器、分子自旋电子器件和分子 p-n 纳结的有序和稳定的分子纳米结构阵列的制造提供了有前途的途径。
