We have measured the bimolecular contribution (relaxivity) R1 (M(-1) s(-1)) to the spin-lattice relaxation rate for the protons of H2 and H2@C60 dissolved in organic solvents in the presence of paramagnet nitroxide radicals. It is found that the relaxation effect of the paramagnets is enhanced 5-fold in H2@C60 compared to H2 under the same conditions. 13C relaxivity in C60 induced by nitroxide ...

In this work, a double-buffer film of TiOx coated with CsOx (TiOx/CsOx) was solution prepared to be applied in poly(3-hexylthiophene):indene-C60 bisadduct (P3HT:ICBA) and P3HT:[6,6]-phenyl-C61-butyric acid methyl ester (PCBM) inverted polymer solar cells (PSCs). Compared with TiOx films and CsOx films, the TiOx/CsOx double-buffer film exhibited a favorable energy-level alignment among TiOx, CsO...

The synthesis of azafullerene C59N is realized through a nitrogen plasma irradiation method, which is confirmed by the analysis of mass spectroscopy. A plasma consisting of a fullerene negative ion C60 and the azafullerene positive ion C59N��C60-C59N plasma��is generated by means of an electron beam ionization. C60 and C59N ions are selectively irradiated to single-walled carbon nanotubes (SWNT...

C60 whiskers are needle-like fullerene structures, formed through polymerisation of individual C60 molecules. A lowcost, room temperature technique for their growth has recently been demonstrated and subsequent electrical characterisation have revealed promising results. Despite the potential for improved electron transport at smaller diameters, data on electrical resistivity have so far been l...

Density functional theory (DFT) calculations were carried out to study the reaction mechanism of the Suzuki-Miyaura rhodium-catalyzed hydroarylation of fullerene (C60) by phenylboronic acid in the presence of water. As found experimentally, our results confirm that addition of the phenyl group and the hydrogen atom in C60 occurs at the [6,6] bond. The rate-determining step corresponds to the si...

Platinum(ii) bis(N-(4-ethynylphenyl)carbazole)bipyridine fullerene complexes, (Cbz)2-Pt(bpy)-C60 and ((t)BuCbz)2-Pt(bpy)-C60, were synthesized. Their photophysical properties were studied by electronic absorption and emission spectroscopy and the origin of the transitions was supported by computational studies. The electrochemical properties were also studied and the free energies for charge-se...

STM has been used to characterize fluctuation properties of segments of step edges partly covered by C60 on Ag 111 at room temperature. The distribution of C60 at step edges exhibits a step orientation dependence: Low-symmetry step edges are more favorable for C60 binding. The temporal correlation functions of step segments between C60-covered step regions scale as a power law, with an average ...

An increase of the intracellular reactive oxygen species (ROS) concentration leads to the development of oxidative stress and, thus, to the damage of cell components. The cause-and-effect relations between these processes have not been fully established yet. The ability of photo excited supramolecular composites containing fullerenes C60 immobilized at nanosilica particles to generate reactive ...

A modeling study of C60 in nanotubes is presented, with focus on a new approach. We report on the elastic properties, energetics, and certain tribological issues, for C60 inside (n, n) nanotubes, with n ranging from 5 to 10. A new combined molecular dynamics/continuum approach with account of both the nonbonded and bonded interactions was used. The elastic properties of the nanotube were analyt...
