通过使用一种新的协议，在空间上限制分子在定义明确的小2D区域，所谓的纳米corpus，我们使用扫描隧道显微镜（STM）显示这种限制如何影响自组装分子网络（SAMN）形成在液-固界面。由纳米皮质的尺寸施加的2D横向限制对可以形成低密度和高密度SAMN两者的分子的相选择性具有明显的影响，高密度相通过限制促进。
By using a novel protocol to spatially confine molecules in well-defined small 2D areas, the so-called nanocorrals, we show using scanning tunneling microscopy (STM) how this kind of confinement affects self-assembled molecular network (SAMN) formation at a liquid-solid interface. The 2D lateral confinement, imposed by the size of the nanocorrals, has a clear impact on the phase selectivity of a molecule that can form both low-density and high-density SAMNs, the high-density phase being promoted by the confinement.
