Boris. A fullerene is an allotrope of carbon whose molecule consists of carbon atoms connected by single and double bonds so as to form a closed or partially closed mesh, with fused rings of five to seven atoms.
The molecule may be a hollow sphere, ellipsoid, tube, or many other shapes and sizes. Graphene (isolated atomic layers of graphite), which is a flat mesh of regular hexagonal rings, can be.

The book begins with introductory chapters that provide the necessary background in experimental and theoretical techniques. Free radical reactions which took place upon warming the glasses to temperatures at which the electron adducts become mobile were studied.
For carboxylic acids (C/sub n/H/sub 2n+1/CO/sub 2/D, n = 2,3) the deuterated anion radicals (RCH/sub 2/C(OD)/sub 2/) give results which suggest abstraction of a hydrogen from the parent acid to produce.

After a short description of the discovery of the fullerenes all methods of the production and isolation of the parent fullerenes and endohedrals are.
Fullerenes, especially C60, exhibit great potential applications in biology field, due to their excellent antibacterial, antiviral, antitumor and other properties.
Many water-soluble fullerene derivatives have been designed, synthesized and used as photo-dynamic therapy agents, antiviral agents, bioimaging agents, drug carriers and so by: 3. The mechanism of the reaction of azafullerene radical C59N• with diphenylmethane and 9-methyl-9H-fluorene has been investigated.
The primary and secondary kinetic isotope effects provide strong evidence for a stepwise mechanism in which the hydrogen-atom abstraction is the rate-determining by: 4. The photo, electrochemical and physical properties of C 60 and other fullerene derivatives finds applications in medical fields.
The ability of fullerenes to fit inside the hydrophobic cavity of HIV proteases makes them potential inhibitor for substrates to catalytic active site of enzyme.

The description of the chemistry of the fullerenes the reduction (Chapter 2), nucleophilic additions (Chapter 3), cycloadditions (Chapter 4), hydrogenation (Chapter 3, radical additions (Chapter 6), transition metal complex formation am also indebted to my co-workers for their assistance in preparing figures and illustrations.
C(60), vitamin E, and three C(60) derivatives (polar 1 and water-soluble C(3)/D(3)C(60)s) were examined for their antioxidant effects on prevention of lipid peroxidation induced by superoxide and hydroxyl by: The fullerenes, particularly the highly symmetrical C 60 sphere, have a beauty and elegance that excites the imagination of scientists and nonscientists alike, as they bridge aesthetic gaps between the sciences, architecture, mathematics, engineering, and the visual to their discovery, only two well-defined allotropes of carbon were known—diamond (composed of a three-dimensional.
Since the first discovery of the well-known class of spherical molecules , fullerenes have attracted worldwide attention due to their unique structure and paved the way in many research areas [2,3,4,5].The research interest in studying such unique molecules is due to their fascinating physical and chemical properties such as the capability of forming endohedral and exohedral derivatives Author: Hamad M.
Al-Matar, Mohammad H. BinSabt, Mona A. Shalaby. Fullerenes and their derivatives have been proposed as free radical scavengers, and a number of investigations have studied fullerene derivatives as potential free radical antioxidant therapeutics, neuroprotectants, anti-inflammatories and others [5,10].

Zard. 34 Epoxides in Titanocene-Mediated and -Catalyzed Radical Reactions Andreas Gansäuer and André. Fullerenes can be of a different type C60, C70, etc., depending on the content of carbon atoms.
The most stable and best studied - is the C60, containing 60 carbon atoms. Fullerene is the only molecular form of carbon, in contrast to the diamond and graphite, which are only crystalline forms with a certain spatial arrangement of carbon atoms in. Fullerenes act as ‘radical sponges’ scavenging around 20 free radicals per molecule of fullerene.
This action is due to the electron deficient alkene nature of fullerenes which take up the electrons and scavenge the radicals. The efficiency of these entities goes up to around times the leading antioxidants. Oxidation causes cell death.

The separation and functionalization of fullerenes is a recent and exciting area of research. The separation methods outlined are intended to increase the availability of endohedral metallofullerenes by decreasing their cost of production.
Functionalized fullerene species were achieved through Bingel and Prato reactions to provide materials. Novel mechanism of antioxidant activity of buckminsterfullerene C60 based on protons absorbing and mild uncoupling of mitochondrial respiration and phosphorylation was postulated.
In the present study we confirm this hypothesis using computer modeling based on Density Functional Theory. Fullerene's geroprotective activity is sufficiently higher than those of the most powerful Cited by:. Due to their attractive physical, chemical, and biological properties and the availability of various methods for surface modification, fullerenes and their derivatives have been studied for their numerous biomedical applications, not only in tumor diagnosis and therapy, but also as an anti-HIV agent [77, 78], antimicrobial photosensitizer [Download Radical Reactions of Fullerenes and their Derivatives!
