The Au(111) single crystal was cleaned by multiple cycles of Ar + sputtering (1 KeV, 4 E-6 mbar, 20 μA for 30 minutes) and flash annealing to 750 K. Functionalized anthracene precursor molecules m1 were sublimed from a custom-built Knudsen cell evaporator at 385 K with the Au(111) surface held at room temperature. The sample was subsequently annealed to 425 K and 525 K.
