An efficient hydrosolubilizing reagent for [60]fullerene (C60) was newly developed with a γ-cyclodextrin (γ-CD) derivative having triazole-methoxypyridyl moieties at its 6-hydroxyl positions (PCD). Through solid-state mechanochemical complexation, PCD forms a hydrosoluble inclusion complex of C60 with a concentration of more than 70 mM. This is approximately 90 times greater than that with non-...

Using the highly localized current of electrons tunneling through a double barrier scanning tunneling microscope junction, we excite luminescence from a selected C60 molecule in the surface layer of fullerene nanocrystals grown on an ultrathin NaCl film on Au(111). In the observed fluorescence and phosphorescence spectra, pure electronic as well as vibronically induced transitions of an individ...

We investigate the effects of C60 fullerene encapsulation on the radial breathing mode (RBM) of semiconducting single-wall carbon nanotubes (SWCNTs) under tunable laser excitations. The changes in the RBM frequencies after C60 insertions show characteristic behavior; higher frequency shifts are observed in the case of smaller diameter tubes (dt<or =1.32 nm) and lower frequency shifts, in the ca...

The regioselective synthesis of easily isolable pure bismethano derivatives of C60 and C70 with high steric congestion is described using 1,3-dibenzoylpropane bis-p-toluenesulfonyl hydrazone as the addend precursor. When the addition occurs at two [6,6] ring junctions within the same hexagon, bisadducts with mirror symmetry are obtained for both C60 and C70. When the addition occurs at two [5,6...

At the nanoscale, even a single atom change in the structure can noticeably alter the properties, and therefore, the application space of materials. We examine this critical behavior of nanomaterials using fullerene as a model structure by a first-principles density functional theory method coupled with nonequilibriumGreen's function formalism. Two different configurations, namely, (i) endohedr...

We study the dynamics of nanoclusters composed of C60 fullerene molecules. We reveal that such composite nanostructures can support long-lived strongly localized nonlinear modes, which resemble discrete breathers in simple nonlinear lattices. In these localized modes, the vibrational energy density is localized predominantly at one of the C60 molecules, and it decays rapidly away from the mode....

Fullerenes C60 have attracted considerable attention in the biomedical field due to their interesting properties. Although there has been a concern that C60 could be metabolized to hydroxylated fullerenes (C60(OH)x) in vivo, there is little information on the effect of hydroxylated C60 on liver cells. In the present study, we evaluated the cytotoxic effects of fullerene C60 and various hydroxyl...

Oxygen adducts were among the first reported fullerene derivatives, and they have continued to be the subject of many subsequent investigations by experimental and theoretical researchers. A literature survey is presented summarizing the preparation, purification, characterization, and stabilities of fullerene oxides and ozonides. Published data on the 13C NMR spectra, thermal dissociation reac...

The effects of germanium tetrabromide addition to tetraphenyl porphyrin zinc (Zn-TPP)/fullerene (C60) bulk heterojunction solar cells were characterized. The light-induced charge separation and charge transfer were investigated by current density and optical absorption. Addition of germanium tetrabromide inserted into active layer of Zn-TPP/C60 as bulk heterojunction had a positive effect on th...

The Front Cover shows the encapsulation of C60 by “iceberg” water, analogous to methodology authors implement acquire enhanced Raman spectra fullerene. More information can be found in Research Article Nathan I. Hammer and co-workers.
