A kind of Gd@C82 salt, Gd@C82/TBPA, was prepared through chemical oxidation. The Gd@C82/TBPA salt was characterized as being paramagnetic with an effective magnetic moment of 9.68μB. The Gd@C82/TBPA salt dissolves in many organic solvents and its high solubility will make it more applicable for use as a magnetic material.

This article reports computations for Al@C82, Sc@C82, Y@C82, and La@C82 based on encapsulation into the IPR (isolated pentagon rule) C2v C82 cage. Their structural and bonding features are also used for evaluations of the relative production yields, employing the encapsulation Gibbs-energy terms and saturated metal pressures. The results can be well related to the ionization potentials of the f...

We previously demonstrated that gadolinium endohedral metallofullerenol Gd@C82(OH)22 nanoparticles had high inhibitory activity on growth of malignant tumor in vivo by uncertain mechanism(s). The activities of enzymes associated with the metabolism of reactive oxygen species (ROS) were decreased in the tumor-bearing mice by intraperitoneally injection of Gd@C82(OH)22 nanoparticles . In current ...

Lanthanide-lanthanide bonds are exceptionally rare, and dimetallofullerenes provide a unique possibility to stabilize and study these unusual bonding patterns. The presence of metal-metal bonds and consequences thereof for the electronic properties of M2@C82 (M = Sc, Er, Lu) are addressed by electrochemistry, electron paramagnetic resonance, SQUID magnetometry and other spectroscopic techniques...

The paper reports computations for Al@C82, Sc@C82, Y@C82 and La@C82 based on encapsulation into the IPR (isolated pentagon rule) C2υ C82 cage and also on Mg@C74, Ca@C74, Sr@C74 and Ba@C74 based on encapsulation into the only C74 IPR cage. Their structural and energetic characteristics are used for evaluations of the relative production yields, employing the encapsulation Gibbs-energy terms and ...

The electronic structure of potassium-doped La@C82 has been studied with synchrotron-radiation photoelectron spectroscopy. Ultraviolet photoemission measurements indicate evolution of the valence-band states of La@C82 with increasing potassium content, but KxLa@C82 remains semiconducting for all x between 0 and 6, with a band gap of at least 0.4 eV, in contrast to K-doped C60. The valence-band ...

Endohedral metallofullerene species with controllable electron spin have attracted increasing attention along with their potential application in quantum information processing. In this paper, we report the electron spin manipulation via encage cluster through comparative studies on the anion radicals of metallofullerene Y2@C82-Cs, Y2C2@ C82-Cs, and Sc2C2@C82-Cs. Although these three radical sp...

[11]Cycloparaphenylene ([11]CPP) selectively encapsulates La@C82 to form the shortest possible metallofullerene-carbon nanotube (CNT) peapod, La@C82 ⊂[11]CPP, in solution and in the solid state. Complexation in solution was affected by the polarity of the solvent and was 16 times stronger in the polar solvent nitrobenzene than in the nonpolar solvent 1,2-dichlorobenzene. Electrochemical analysi...

The electronic structures of nanopeapods that consist of a semiconducting nanotube and various fullerenes, such as C60, C82, La@C60, and La@C82 are investigated using a first-principles method. For all the systems studied, molecular states originating from fullerenes are found within the energy gap of the semiconducting nanotube, often resulting in effective hole doping of nanotubes as the Ferm...

Unimolecular decompositions of noble gas containing endohedral fullerenes as well as metallofullerenes were studied using tandem mass spectrometry techniques. Endohedral fullerenes do not lose the endohedral atom unimolecularly but fragment via the loss of C2 units. Kinetic energy release distributions were measured for the emission of C2 units from the positive ions of C60, Ne@C60, Ar@C60, Kr@...
