Physics And Chemistry Of Fullerenes And Derivatives

The year 1995 witnessed the tenth anniversary of the International Winterschools in Kirchberg, Tyrol/Austria. These schools are devoted to the Electronic Properties of Novel Materials, having started with coverage of research on conducting polymers and high temperature superconductors to presently focusing on Fullerene, the newly discovered third allotrope of carbon.This year's proceedings present about ten tutorial and review papers on physics, chemistry, and material science of Fullerene, Fullerene derivatives and nanotubes, as well as bout a hundred research contributions on the latest development in this field including a summary on the assessment of the applications potential of the materials and phenomena which have already evolved from the activities in the past couple of years.

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.

Fullerenes-a guide to the current state of knowledge in the field The last decade has seen an explosion of research into the chemical and physical properties of a promising new class of carbon-based materials known as fullerenes. Karl Kadish and Rodney Ruoff, two highly recognized leaders in the fullerene and nanotube research community, edit a comprehensive and much-needed survey of this important and rapidly evolving field. Contributions by experts in diverse areas of chemistry, physics, pharmacology, materials science, and chemical engineering provide an excellent introduction to fullerenes and highlight their considerable potential in such cutting-edge applications as semiconductor materials, new pharmaceutical compounds, and polymers. From the electrochemistry of fullerenes to molecular and solid C36, this book offers a remarkably fresh and authoritative look at some of the hottest research topics today, including: * Organic functionalization of fullerenes * Photophysical properties of different types of fullerenes * Polyfunctional polymer derivatives of fullerenes * The theory and production of endohedral metallofullerenes * Fullerene surface interactions * Superconductivity in fullerenes * Synthesis of materials incorporated within carbon nanotubes

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.

The creation of the hollow carbon buckminsterfullerene molecule as well as methods to produce and purify bulk quantities of it has triggered an explosive growth of research in the field. Superconducting and magnetic fullerides, atoms trapped inside the fullerene cage, chemically bonded fullerene complexes, and nanometer-scale helical carbon tubes are some of the leading areas that have generated much excitement.This book is intended as a guide to the literature for the scientist who is just entering fullerene research, and will be one more valuable volume to the collection for the established worker. It contains reprints of some sixty most important research papers, with focus especially on those papers that have guided further work in the field. There is also a short review of the field, with references to many other publications.
