We present a theoretical study of a new hybrid compound, where the C60 molecules are encapsulated in a recently discovered metal-organic framework (MOF). Being placed in a rigid skeleton, the fullerene molecules form a cubic crystal, while the intermolecular distance of the fullerenes is tuned by the choice of appropriate organic linkers of the MOF structure. The resulting C60 crystal shows a d...
Four ionic fullerene derivatives, which are relatively soluble in polar solvents, are shown to organize into morphologically different nanoscale structures. Spheres, nanorods, and nanotubules form in water depending on the side chain appendage of the fullerene spheroid. Images at different nanoscale structures were obtained via transmission electron microscopy. Also, computer simulations were u...
Interpretation of electron diffraction patterns from amorphous and fullerene-like carbon allotropes.
The short range order in amorphous and fullerene-like carbon compounds has been characterized by selected area electron diffraction (SAED) patterns and compared with simulations of model nanoclusters. Broad rings in SAED pattern from fullerene-like CN(x) at approximately 1.2, approximately 2, and approximately 3.5A indicate short-range order similar to that in graphite, but peak shifts indicate...
Creation of new biocompatible nanomaterials, which can exhibit the specific biological effects, is an important complex problem that requires the use of last accomplishments of biotechnology. The effect of pristine water-soluble fullerene C60 on ATPase activity and superprecipitation reaction of rabbit skeletal muscle natural actomyosin has been revealed, namely an increase of actomyosin superp...
Fullerene C60 compound was recently found to be a potent anti-oxidant, which may be envisioned as a result of alteration of the inner mitohondria membrane electric potential with protons transport boosted by fullerenes. Here we briefly report on the theoretical test of the very possibility of protons to pass through the surface of C60 fullerene to become confined within latter thus possibly dec...
Enumeration of chiral isomers of substituted fullerene cages (CZO-C~O) is considered using the generalized character cycle index (GCCI) of the alternating representation of the point group of the parent cage. It is shown that there are no chiral isomers for the monosubstituted CZO, c24, C28, C30, c36, and CW fullerene cages but there are chiral isomers for other monosubstituted cages. All cages...
Fullerene graphs are mathematical models of fullerene molecules. The Wiener (r,s)-complexity a graph G with vertex set V(G) is the number pairwise distinct values (r,s)-transmiss...
A molecular donor-acceptor dyad comprising a hexarhenium cluster core, [Re(6)(mu(3)-Se)(8)](2+), and a fullerene moiety which are covalently linked through a pyridine ligand was synthesized and fully characterized. The electrochemical and photophysical properties are reported. The detailed study includes cyclic voltammetry, steady-state absorption and fluorescence spectroscopy, radiation chemis...
We demonstrate that intercalation of fullerene derivatives between the side chains of conjugated polymers can be controlled by adjusting the fullerene size and compare the properties of intercalated and nonintercalated poly(2,5-bis(3-hexadecylthiophen-2-yl)thieno[3,2-b]thiophene (pBTTT):fullerene blends. The intercalated blends, which exhibit optimal solar-cell performance at 1:4 polymer:fuller...
Fullerene (C60) films were prepared on Si, ITO, and Cu substrates by the physical vapor deposition (PVD) method. It was observed that the morphology and structure of fullerene films strongly depend on the substrates. Along with the interactions between fullerenes and substrates increasing from ITO, Si to Cu substrate, C60 forms small polycrystalline grains, large polycrystalline grains and full...
