Book Description
The discovery of fullerenes, species belonging to the electronodeficient polyalkenes with weakly conjugated double bonds, has opened novel opportunities for the radical chemistry. Pioneering study in this field was performed by P. J. Krusic, E. Wasserman, P. N. Keizer, J. R. Morton, and K. F. Preston (Science, 1991, 254, 1184). The fullerenyl radical adducts formed via addition of atoms or free radicals to fullerenes have no analogs in organic chemistry. In fact, radicals in which the unpaired electrons are delocalized over the surface of a sphere or ellipsoid have never been studied before. The unusual character of the fullerenyl radicals is also due to the fact that they occupy a sort of intermediate position between the planar and tetrahedral radicals. Thus, the elucidation of the characteristic features of fullerenyl radicals and their reactivity by EPR spectroscopy, and the comparison of the results with those of quantum-chemical studies are of fundamental importance. Isolation of the products from homolytic reactions of fullerenes in bulk amounts opens the door to large-scale preparation of new organic and organoelement derivatives of including biologically active ones. Radical reactions of fullerenes find wide application in the synthesis of fullere- containing polymers with valuable photophysical characteristics. Ferromagnetism of the complex of with tetra(dimethylamino)ethylene found lends impetus to a search of novel methods for preparation of biradicals one unpaired electron of those is located on the fullerene cage while the other retained by the addend.

Book Description
Nanocarbon chemistry and physics is a fast-developing, broad research area – the Nobel prizes in 1996 and 2010 awarded to two key discoveries in the field, and several other nanocarbon achievements of comparable importance. Owing to this rapid growth, the nanocarbon landscape fundamentally changes every few years, creating a need to survey the field on a regular basis to update the books that have become incomplete or even obsolete. As such, this book focuses on fullerenes and metallofullerenes and also on the related areas of nanotubes and graphenes. All the covered research topics provide important fundamental knowledge for the natural sciences, but also for applications in molecular electronics, superconductivity, catalysis, photovoltaics and medical diagnostics. The current nanocarbon research activities have particularly high application potential in the conversion of solar energy, future molecular memories, non-conventional materials for optoelectronics, and new treatments for civilization diseases. Offering a truly up-to-date critical survey of nanocarbon science, its concepts and highlights, it follows the concept of a handbook: it addresses key topics systematically, from historical background, methodological aspects, current important issues, and application potential, all supplied with extensive referencing. With individual chapters written by leading experts with extensive research experience, it is a comprehensive reference resource for graduate students and active researchers alike.

Book Description
The closed-cage carbon molecules known as fullerenes provide an entirely new branch of chemistry, materials science, and physics. Fullerene research is now engaging the frenetic attention of thousands of scientists. Initially, the chemistry was relatively slow to develop due to the low availability of material, and the need for state-of-the-art instrumentation for product analysis. This research area is now very definitely up-and-running, and will soon become the main focus of attention in the fullerene field. The number of published papers already runs into hundreds, and the main features of fullerene reactivity have been established. This book describes all of the known types of reactions as well as the means of production, the purification, and the properties of fullerenes.

Book Description
Fullerenes and nanotubes are two classes of carbon structures or allotropes, which were discovered about 17 years ago. Since that time, many chemical derivatives have been synthesized using fullerenes and nanotubes as building blocks. Particularly promising was the theory that the chemical properties of fullerenes, and certain derivatives, made them likely candidates for anticancer drugs, inhibitors of viruses such as HIV, or even as anti-bacterials. Their cyctotoxicity can also be controlled by specific circumstances. In addition, the funtionalization of nanotubes has not only produced relatively simple derivatives, but also complex hybrids with biological macromolecules, which show unique supramolecular architecture and which are promising in many medical applications. The application of fullerenes and nanotubes in medicine is at the frontier of our knowledge, thus the work in this field represents the basis for future novel developments.

Book Description
Until 1985, the chemical element Carbon was only known to exist in two forms -- diamond and graphite. This changed when Kroto and co-workers discovered an entirely new form of carbon, which became known as C60 or the fullerene molecule. (This discovery later led to their award of the 1996 Nobel Prize in Chemistry.) The original discovery of C60 was in the soot produced from the laser ablation of graphite. Since then, other methods of production have been developed. It is also thought that isolated C60 molecules may be found in stars and interstellar media. It was soon discovered that C60 is not the only ball-like carbon molecule possible (although it is the most stable and the most dominant). The rugby-ball shaped C70 molecule is another possibility. In nanotechnology, the potential applications of carbon nanotubes (formed by combining hexagonal rings of carbon atoms only, rather than hexagons and pentagons as in C60) for very small electronic devices are currently the subject of much activity. This book presents the latest research in this dynamic field.

Book Description
The fullerenes, hailed as one of the discoveries of the century, have created whole new fields of organic/organometallic chemistry and of physics. Together with the related nanotubes, they hold the promise of providing new materials with novel chemical and solid state properties. The cost of the basic fullerenes is now such that research into them is feasible for very many chemists.This book describes the fundamental aspects of fullerene chemistry. Following brief background on the discovery, basic fullerene nomenclature, and relevant properties (including those of endohedral fullerenes and nanotubes), there are chapters describing the rules governing the addition patterns, and each of the reaction types with representative examples. Leading references are given to key papers describing individual reactions and phenomena.
