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 are substantially affected by the cycloaddition. Submonolayers of the physisorbed derivatives exhibit magnetic hysteresis on an Au(111) surface at 2 K as revealed by X-ray magnetic circular dichroism.
富勒烯单分子磁体（SMMs）DySc2N@C80 和 Dy2ScN@C80 通过表面锚固硫醚基团的 1,3-偶极环加成进行功能化。Dy-富勒烯的 SMM 性质受到环加成的显著影响。物理吸附衍生物的亚单层在 2 K 下通过 X 射线磁圆二色性在 Au(111)表面上显示出磁滞。
