偶极铱配合物的高度分散的上层结构在Cu（111）表面形成。我们发现具有密度控制的分子间分离的稀超结构是由强的和远程的分子间排斥相互作用稳定的。利用低温扫描隧道显微镜定量评价了分子间的排斥性相互作用，其特征是表面增强的偶极子-偶极子相互作用。
Highly dispersed superstructures of a dipolar iridium complex are formed on a Cu(111) surface. We show that the dilute superstructures with density-controlled intermolecular separations are stabilized by the strong and long-range repulsive intermolecular interactions. The repulsive intermolecular interactions are quantitatively evaluated by using low-temperature scanning tunneling microscopy, which are characterized by the surface-enhanced dipole-dipole interactions.
