Non-Chromatographic Purification of Endohedral Metallofullerenes [PDF]

Molecules, 2017
The purification of endohedral metallofullerenes by high performance liquid chromatography is very time-consuming and expensive. A number of rapid and inexpensive non-chromatographic methods have thus been developed for large-scale purification of metallofullerenes.

Metal‐Induced Tuning of Fullerene Reactivity: Application to Nucleophile Addition [PDF]

ChemPhysChem, Volume 26, Issue 23, November 28, 2025.
A textbook case of how encapsulating an atom in a carbon cage can tune assembly reactivity based on partial charge distribution–exemplified by the classic nucleophilic attack. Endohedral metallofullerenes (EMFs) are a unique class of hybrid molecules formed by encapsulating metal atoms within carbon cages (fullerenes), giving rise to distinctive ...

Functionalization of Endohedral Metallofullerenes with Reactive Silicon and Germanium Compounds [PDF]

Molecules, 2017
Exohedral derivatization of endohedral metallofullerenes (EMFs) has been exploited as a useful method for characterizing the structural and chemical properties of EMFs, and for functionalizing them for potential applications.

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

Angewandte Chemie, Volume 137, Issue 16, April 11, 2025.
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).

Thermodynamically stable [4 + 2] cycloadducts of lanthanum-encapsulated endohedral metallofullerenes [PDF]

Beilstein Journal of Organic Chemistry, 2014
The [4 + 2] cycloaddition of o-quinodimethanes, generated in situ from the sultine 4,5-benzo-3,6-dihydro-1,2-oxathiin 2-oxide and its derivative, to La metal-encapsulated fullerenes, La2@C80 or La@C82, afforded the novel derivatives of endohedral ...

DFT Calculations of Structure and IR Spectra of Gd₂@C₈₂ Endofullerenes [PDF]

Molecules
Dimetallofullerenes are obtained in synthesis in parallel to monometallofullerenes, but they are less studied because their yields are considerably lower. In this work, DFT modeling of Gd2@C82 endohedral metallofullerene (EMF) has been performed. A total

DFT Study of NO and NO₂ Adsorption onto Endohedral Metallofullerenols (M@C₆₀(OH)_n; M = Li, Ca, Y; n = 0, 6, 12, 18, 24) [PDF]

Molecules
Nitrites and nitrates are admitted into the body through the consumption of various foods, primarily cured meat products. These nitrites and nitrates are precursors of reactive nitrogen species NO and NO2, which, in excess, promote nitrosative stress ...

Controlling the reactivity of La@C82 by reduction: reaction of the La@C82 anion with alkyl halide with high regioselectivity [PDF]

Beilstein Journal of Organic Chemistry, 2023
Endohedral metallofullerenes have excellent redox properties, which can be used to vary their reactivity to certain classes of molecules, such as alkyl halides. In this study, the thermal reaction of the La@C2v-C82 anion with benzyl bromide derivatives 1

DFT Calculations of Structure and IR Spectra of M@C₆₀ and M₂@C₆₀ Endofullerenes (M=Sc and Y) [PDF]

Molecules
The endohedral metallofullerenes with a rare-earth metal encapsulated into the carbon cage are nanoparticles with potentially wide applications. We present the results of our quantum-chemical modelling of Sc@C60, Y@C60 and Sc2@C60, Y2@C60 endofullerenes ...

Endohedral metallofullerenes in self-assembled monolayers

Phys. Chem. Chem. Phys., 2010
A method has been developed for the attachment of a dithiolane group to endohedral metallofullerenes via a 1,3-dipolar cycloaddition reaction. This sulfur-containing functional group serves as an anchor, enabling efficient immobilisation of endohedral fullerenes on Au(111) surfaces at room temperature, directly from the solution phase.
