N2 - Structure formation in an ionic liquid adlayer: First molecularly resolved scanning tunneling microscopy images of an ionic liquid adlayer ([Py1,4]+ [FAP]− (see image)), evaporated on a Au(111) surface, resolve a molecular pattern at 210 K with a distinct short range order, indicating a 2D solid, while at room temperature, the mobility of the adlayer is too high to resolve molecular features, as expected for a 2D liquid.
