Buckminsterfullerene is the most common naturally occurring fullerene. Small quantities of it can be found in soot. [5] [6] It also exists in space. Neutral C 60 has been observed in planetary nebulae [7] and several types of star. [8]
According to the IUPAC, to name a fullerene, one must cite the number of member atoms for the rings which comprise the fullerene, its symmetry point group in the Schoenflies notation, and the total number of atoms. For example, buckminsterfullerene C 60 is systematically named (C 60-I h)[5,6]fullerene. The name of the point group should be ...
Scheme 1 presents an overview of the first step, the creation of a 13 membered ring orifice on the fullerene surface. A 1,2,4-triazine 2 is fitted with two phenyl groups and a pyridine group for reasons of solubility and reacted in 1,2-dichlorobenzene with pristine C 60 fullerene 2 in a Diels-Alder reaction at high temperature and for an extended reaction time.
The calculated data allows using C 60 fullerene as a Faraday cage, [13] which isolates the encapsulated atom from the external electric field. The mentioned relations should be typical for the more complicated endohedral structures (e.g., C 60 @C 240 [14] and giant fullerene-containing "onions" [15]).
The United States Food and Drugs Administration is warning pet owners about a common medication given to pets to treat arthritis. The F.D.A. now says that the drug Librela may be associated with ...
A transition metal fullerene complex is a coordination complex wherein fullerene serves as a ligand. Fullerenes are typically spheroidal carbon compounds, the most prevalent being buckminsterfullerene, C 60. [2] One year after it was prepared in milligram quantities in 1990, [3] C 60 was shown to function as a ligand in the complex [Ph 3 P] 2 ...
