Triazoliumfullerene was first prepared by the [3+2] cycloaddition of in situ generated 1,3-diaza-2-azoniaallene with fullerene and was characterized by the dispersed positive charge over the fullerene sphere associated with periconjugation. This new type of amphiphilic fullerene tended to form vesicles and crystalline aggregates after the casting of THF or MeOH solutions.
A novel Ag(I)-induced three-component annulation reaction of [60]fullerene with sulfonylhydrazones and nitriles has been developed for the efficient synthesis of diverse disubstituted [60]fullerene-fused dihydropyrroles. The reaction exhibits a broad substrate scope and excellent functional-group tolerance, and also allows for the synthesis of fullerene-bound macromolecules.
Well-dispersed mesoporous hollow silica-fullerene nanoparticles with particle sizes of ∼50 nm have been successfully prepared by incorporating fullerene molecules into the silica framework followed by a selective etching method. The fabricated fluorescent silica-fullerene composite with high porosity demonstrates excellent performance in combined chemo/photodynamic therapy.
in this paper, we calculate the eccentric connectivity index and the eccentricity sequence of two infinite classes of fullerenes with 50 + 10k and 60 + 12k (k in n) carbon atoms.
Zero-dimensional fullerenes can modulate the biological behavior of a variety of cell lines. However, the effects and molecular mechanisms of proliferation and cardiomyogenic differentiation in brown adipose-derived stem cells (BADSCs) are still unclear. In this study, we report the initial biological effects of fullerene-C60 on BADSCs at different concentrations. Results suggest that fullerene...
Background & Aims: According to the recent studies, fullerene nanoparticles have a potent scavenging property for free radicals in biological environments. Since reactive oxygen species (ROS) is a fundamental mechanism of brain damage in stroke, we aimed to evaluate the neuroprotective effects of fullerene nanoparticles on ischemia-induced brain injuries in experimental model of stroke...
The influence of crystallinity on exciton diffusion and fullerene distribution was investigated by blending amorphous and semicrystalline copolymers. We measured exciton diffusion and fluorescence quenching in such blends by dispersing fullerene molecules into them. We find that the diffusion length is more than two times higher in the semicrystalline copolymer than in the amorphous copolymer. ...
The review focuses current research in the rapidly developing chemistry of porphyrin-fullerene complexes, and highlights recent advances in the synthesis, properties, and potential applications of this family. An overview of the most popular methods to prepare porphyrin complexes with C60 fullerene exhibiting various types of linkage is given with the main focus on the Prato reaction and its mo...
