♦ Synthesis of Novel Endohedral Metallofullerene

We have successfully synthesized and isolated Sc₂C₂@C_s(hept)-C₈₈, which is the first example of an endohedral carbide fullerene with a heptagon ring on the carbon cage and only the second endohedral fullerene to contain a heptagon. The X-ray crystal structure of Sc₂C₂@C_s(hept)-C₈₈ reveals that a zigzag Sc₂C₂ unit was encapsulated in an unprecedented C_s(hept)-C₈₈ cage. Calculations suggest that this endohedral fullerene could be a kinetically trapped species derived from the recently reported Sc₂C₂@C_2v(9)-C₈₆ via a direct C₂ insertion.

♦ Functionalized Fullerenes in Self-Assembled Monolayers

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.
