Abstract The formation of the interface between C 60 thin films and the Cu(110) surface has been investigated in situ using reflectance difference spectroscopy (RDS). The electronic interaction between C 60 molecules in the first monolayer and the substrate inhibits low‐energy intramolecular transitions, whereas the C 60 molecules above the first monolayer are effectively decoupled from the substrate. The morphology of C 60 thin films prepared at room temperature is thermally stable up to 500 K. Above this threshold, optical spectroscopy and low energy electron diffraction (LEED) indicate the formation of rather large three dimensional C 60 islands on a one monolayer thick wetting layer.
