| Özet |
| This work describes a trimesic acid (TMA) network formed at the open-circuit potential (OCP, ∼0.13 V) on Au(111), which we investigate with electrochemical scanning tunneling microscopy (STM). The unit cell of the TMA network at the OCP was (5√3 × 5√3)R30°–4TMA, while that of a well-known honeycomb network of flat-lying TMAs at −0.1 V was (6 × 6)R30°–2TMA. The most significant difference between the two networks is the fraction of hydrogen bonds appearing as bright spots in the STM images: it is 1/3 in the former but 1 in the latter. Additional differences were the shapes and lengths of the STM spots and the packing density of TMAs. A contoured network composed of crownlike anionic TMA hexamers was proposed to explain all the differences. The TMAs in the crownlike hexamer were rotated along the molecular axis and were tilted up from the surface by ∼30° to have hydrogen bonds with … |
