An operation on trivalent graphs leads from the truncated cube to buckminsterfullerene, and C60 is the only fullerene with disjoint pentagons which can be obtained by this method. The construction and the proof emphasize maximal independent sets that contains two fifths of vertices of trivalent graphs. In the case of C60 these sets define the structure of experimentally obtained bromofullerene ...

purpose: today considerable advances have been achieved in application of nano-particles.   fullerene is one of the artificial forms of carbon element. long life cycle of medicines in the   human body is a success factor in delivery of medicine to the specific place. lots of nanoparticles   are being developed in this field and from a medical point of view, achieving such   goals is vital. the ...

In this study, the influence of fullerene junction on the chemical features of 16 different drugs including Captopril, Clonidine, Methyldopa, Naphazoline, Oxymetazoline, Tetrahydrozoline, Xylometazoline, Tolazoline, Clemastine, Procyclidine, Tyramine, Nicotine, Dextroamphetamine, Fluoxetine, Metoprolol and Enalapril was investigated computationally. For this purpose, the mentioned drugs were pl...

We show that the surface-supported two-dimensional covalent organic framework (COF) known as COF-1 can act as a host architecture for C60 fullerene molecules, predictably trapping the molecules under a range of conditions. The fullerenes occupy the COF-1 lattice at the solution/solid interface, and in dried films of the COF-1/fullerene network that can be synthesized through either drop-deposit...

in this research at the first, captopril drug (ca) and its fullerene connected form (fca) wereoptimized. natural bond orbital (nbo) calculations for these compounds were carried out at theb3lyp/6-31g quantum chemistry level, in the gas phase and the liquid phase. these calculations canbe performed at different accuracy levels depending on the aim of the theoretical study [1]. forinstance, densi...

The first icosacationic bis(fullerene) whose water solubility is provided by twenty peripheral ammonium groups has a rigid, almost cylindrical shape and was synthesized by connecting two fullerene cores with a chiral cyclo-bis(malonate), followed by the regioselective addition of ten amino-terminated malonates into the octahedral positions of the fullerene moieties and subsequent cleavage of th...

We have demonstrated that NBS is able to promote the oxidation of fullerene monoradicals to form 1,4-difunctional fullerenes. The singly bonded fullerene dimers were used as fullerene monoradical precursors, which produced various 1,4-fullerenes with a wide range of functional groups in good to high yields with high regioselectivity in terms of cosolvents and nucleophiles.

After last six year e orts which are manifested by hundreds of papers on the physics, chemistry of the fullerenes and the fullerene based materials it is known a lot about the electronic structure of the single macromolecule which is the base of the di erent materials like the doped solids and the chemical adducts. A variety of the computational methods, from ab initio calculation to an empiric...

Obesity and its associated metabolic diseases represent some of the most rapidly expanding health issues worldwide, and, thus, the development of a novel chemical compound to suppress adipogenesis is strongly expected. We herein investigated the effects of water-soluble fullerene derivatives: a bis-malonic acid derivative and three types of proline-type fullerene derivatives, on adipogenesis us...

How to create novel desired structures by rational design of building blocks represents a significant challenge in materials science. Here we report a conceptually new design principle for creating supracolloidal fullerene-like cages through the self-assembly of soft patchy particles interacting via directional nonbonded interactions by mimicking non-planar sp2 hybridized carbon atoms in C60.
