A rectangular (3 x 2 radical3) surface lattice for long-term-annealed dodecanethiol self-assembled monolayers on Au(111) is observed by ultra-high-vacuum scanning tunneling microscopy. The new lattice has the same density and a unit cell of the same size as the well-known c(4 x 2) reconstruction. In contrast, it does not show hexagonal symmetry but rather a sort of thiol pairing, leading to a shift in the binding position of every second molecule. The described structure is believed to be an intermediate phase close to desorption.
通过超高真空扫描隧道显微镜观察到，在金（111）上长期退火的十二烷硫醇自组装单分子层呈现出矩形（3×2√3）表面晶格。这种新晶格与著名的c（4×2）重构具有相同的密度和相同大小的晶胞。相比之下，它不具有六边形对称性，而是呈现出一种硫醇配对现象，导致每隔一个分子的结合位置发生偏移。所描述的结构被认为是接近解吸的中间相。
