Trinuclear gold(I) pyrazolates can bind strongly to electron-poor aromatic compounds, and are therefore promising for the use in selective sensors. STM was used to study layers of AuC18  at the 1-octanoic acid/graphite interface, and different morphologies, monomeric and dimeric, were observed. Dynamic aspects of the layer were also studied on the molecular level, showing rotation of dimer pairs. Insights into such dynamics on the surface will be of great importance for the understanding (and control) of molecular monolayers.
