The capability of scanning tunneling microscopy to image individual molecules intercalated under graphene is demonstrated for fullerenes. The C 60 molecules become visible through the graphene carpet grown on Ni(111) due to an extremely strong bias‐dependent spectroscopic contrast. Its origin is a blocking of the chemical interaction between graphene and its substrate by the fullerenes.
