Nanorods of Endohedral Metallofullerene Derivative

Journal of the American Chemical Society, 2007
Nanorods of La@C82(Ad) (Ad = adamantylidene) were prepared via the liquid−liquid interfacial precipitation method. From the SEM, HRTEM, EELS, and SADEP analyses, it was revealed that the nanorods consist of a single crystal of La@C82(Ad). The field-effect transistor (FET) measurement of the La@C82(Ad) nanorods shows a p-type action.

Inverse Electron Demand Diels-Alder Reaction on M₃N@C₈₀ (M=Lu, Sc): Reactivity and Reversibility Enable Chemical Separation of Metallofullerenes. [PDF]

Angew Chem Int Ed Engl
An inverse electron demand Diels–Alder (IEDDA) reaction on M3N@Ih‐C80 (M=Lu, Sc) has been utilized to yield [5,6]‐closed [4+2] cycloadducts that were fully characterized (HPLC, MS, UV/Vis and NMR spectroscopy, X‐ray crystallography, and DFT calculations).

Metallofullerenol Sc₃N@C₈₀(OH)₁₈: A New Generation Radioprotector Protecting Human Erythrocytes Against Multiple Biochemical Damage Modes Upon Gamma Irradiation, Identifying It as a Scavenger of Short- and Long-Lived Radicals. [PDF]

Adv Healthc Mater
Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.

Ti2C80 is more likely a titanium carbide endohedral metallofullerene (Ti2C2)@C-78 [PDF]

, 2005
We show by means of density functional calculations that the previously synthesized metallofullerene Ti2C80 does not take the form of Ti-2@C-80, but is a titanium carbide endohedral metallofullerene, Ti2C2@C-78, that has a C-78(6-)(D-3h) cage which ...

Enantioselective Synthesis of Endohedral Metallofullerenes

Journal of the American Chemical Society, 2011
Endohedral metallofullerenes are promising materials in biomedical and material sciences. In particular, they are of interest as agents for magnetic resonance imaging (MRI), photovoltaic devices, and semimetallic components. The synthesis of chiral endofullerenes represents one step further in the potential use of these carbon allotropes; however, this
