Surface-induced fragmentation of higher fullerenes and endohedral metallofullerenes [PDF]

, 1999
We report the first results of surface collisions of pure hollow fullerenes (C_60, C_70 and C_78) and endohedral metallofullerenes (Y@C_82, Ca@C_82 and Ca@C_84), isolated by liquid chromatography, against solid (silicon and gold) surfaces and self ...

The Isolation of Endohedral Metallofullerenes with Octadecylsilica Columns

, 1997
Octadecylsilica (ODS) columns have been used for the first time in the purification of endohedral metallofullerenes. In the absence of any pi-pi interaction between the analytes and the stationary phase, the separation selectivity of fullerenes and ...

Electrically controlled nonvolatile switching of single-atom magnetism in a Dy@C84 single-molecule transistor

Nature Communications
Single-atom magnetism switching is a key technique towards the ultimate data storage density of computer hard disks and has been conceptually realized by leveraging the spin bistability of a magnetic atom under a scanning tunnelling microscope.

Geometries, Electronic Structures, Bonding Properties, and Stability Strategy of Endohedral Metallofullerenes TM@C₂₈ (TM = Sc⁻, Y⁻, La⁻, Ti, Zr, Hf, V⁺, Nb⁺, Ta⁺)

Inorganics
We performed quantum chemical calculations on the geometries, electronic structures, bonding properties, and stability strategy of endohedral metallofullerenes TM@C28 (TM = Sc−, Y−, La−, Ti, Zr, Hf, V+, Nb+, Ta+). Our calculations revealed that there are

Efficient N,N-dimethylformamide extraction of endohedral metallofullerenes for HPLC purification

, 1996
A new and efficient extraction method using DMF (N,N-dimethylformamide) was developed to concentrate endohedral metallofullerenes. This single-step extraction method obtained a solution containing 5-15% endohedral metallofullerenes and strongly ...

Different Extraction Behaviors between Divalent and Trivalent Endohedral Metallofullerenes

, 2016
On the basis of high-yield preparation, arc-produced soot containing endohedral Y, La, Nd, Sm, Gd, Tb, Yb, Ca, and Ba fullerenes are successively extracted with carbon disulfide, N,N-dimethylformamide, pyridine, and aniline.

Clusters Encapsulated in Endohedral Metallofullerenes: How Strained Are They?

, 2016
Endohedral clusters in metallofullerenes can vary in a broad range of geometrical parameters following the size and shape of the host carbon cage.

Isolation of Various Endohedral Metallofullerenes with a More Efficient Lewis Acid [PDF]

, 2014
We strive to develop new separation strategies for isolating endohedral metallofullerenes, which contain clusters of metals, carbides, nitrides, or oxides that are trapped inside fullerene cages.
