以末端炔基1，4-二乙炔基-2，5-二甲苯为稳定剂，在Ag（111）表面制备了具有可调金属原子密度的银吸附原子二维有序阵列，并通过扫描隧道显微镜和密度泛函理论计算对其进行了研究.吸附原子阵列的稳定性归因于银吸附原子和分子中末端炔基的基底介导的电子局域化。
Ordered two-dimensional arrays of silver adatoms with tunable metal atom density stabilized by 1,4-diethynyl-2,5-dimethylbenzene, a terminal alkyne, were prepared on Ag(111) and scrutinized by scanning tunneling microscopy and density functional theory calculations. Stabilization of the adatom arrays was attributed to the substrate-mediated electron localizations of the Ag adatom and terminal alkynyl in the molecule.
