Fullerene single molecule magnets (SMMs) DySc2N@C80 and Dy2ScN@C80 are functionalized via a 1,3-dipolar cycloaddition with surface-anchoring thioether groups. The SMM properties of Dy-fullerenes substantially affected by the cycloaddition. Submonolayers physisorbed derivatives exhibit magnetic hysteresis on an Au(111) surface at 2 K as revealed X-ray circular dichroism.
