Physical Review B, 1992
To understand fullerenes, it is crucial to determine the energies, and hence the relative stabilities, of different structures. Here we introduce an approach to calculating and understanding these energies, by applying elasticity theory. Explicit formulas are given for the energies of ball-shaped molecules, graphite tubules, and the recently proposed ...

Chemistry - A European Journal, 2001
Recent developments in fluorination of fullerenes coupled with HPLC separation have permitted the isolation and subsequent structural characterisation of many derivatives, a number of which have novel and unexpected structures. The good solubility of fluorofullerenes, high reactivity towards nucleophiles and enhanced dienophilicity of the unsubstituted

Fullerene-fullerene collisions: Fragmentation and electron capture
Physical Review A, 1995In this paper, we describe collisions between high-energy (100-keV) fullerene ions (${\mathrm{C}}_{60}^{+}$, ${\mathrm{C}}_{60}^{2+}$, ${\mathrm{C}}_{70}^{2+}$, and ${\mathrm{C}}_{70}^{3+}$) and ${\mathrm{C}}_{60}$. The fast, forward-directed charged collision products are identified, leading to information on electron capture and loss as well as ...

Toxicity of functionalized fullerene and fullerene synthesis chemicals
Chemosphere, 2018Fullerene is one of the most studied carbon-based nanoparticles due to its unique structure and potential for diverse applications. This study focuses on toxicological effects of two fullerene nanomaterials, contributing to ecological as well as human risk assessment strategies.

Conformational Barrier for Fullerene−Porphyrin−Fullerene Triad
The Journal of Physical Chemistry B, 2008A recent study (J. Phys. Chem. B 2006, 110, 5337) proposed that fullerene-porphyrin-fullerene triad (C60PC60) could be utilized as a photoinduced switch due to the difference in electron transfer directionality for the cis and trans conformer. It is found that the rotational barrier between the SS and AA conformers of C60PC60 is about 3-5 kcal/mol ...

Raman spectroscopy of fullerenes and fullerene–nanotube composites
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004The discovery of fullerenes in 1985 opened a completely new field of materials research. Together with the single-wall carbon nanotubes (SWCNTs) discovered later, these curved carbon networks are a playground for pure as well as applied science. We present a review of Raman spectroscopy of fullerenes, SWCNTs and composite materials.

Methylation of [76]fullerene by reaction with Al-Ni alloy/NaOH followed by quenching of the intermediate anions with methyl iodide gives a mixture of methylated and methylenated products together with oxide derivatives. The major derivatives are five isomers of C(76)Me(2)(one of C(s) symmetry due to 1,6-C(76)Me(2)) and C(76)(CH(2))(n)(n= 2-4), together
