ful·ler·ene

 (fo͝ol′ə-rēn′)
n.
An allotrope of carbon composed of any of various cagelike molecules that consist only of an even number of carbon atoms, are often spherical in shape, and are composed of hexagonal and pentagonal groups of atoms.

[After Richard Buckminster Fuller (from the resemblance of their configurations to his geodesic domes) + -ene.]

With an account of the spherical symmetry of a fullerene, for the wave function we use the standard ansatz [psi](r, v, [psi]) = R(r)[Y.sub.lm](v, [psi]).
Three-dimensional molecule editing techniques and structural optimization using semiempirical PM7 Hamiltonian [4], and molecular docking were used to predict in silico the interaction energy between Ops pesticides and fullerene derivatives, designed based on AChE active site, as target to the organophosphates compounds, to describe in molecular level the interaction of Ops with proposed molecules.
Although the properties of diamond and graphite have been extensively analyzed, other allotropic forms of carbon such as fullerene, carbon nanotubes (CNT), or graphene are of recent interest (Figure 1).
One of the main causes of the relatively low efficiency of polymer solar cells is incomplete harvesting of solar photons, which is due to the relatively narrow absorption spectrum of the polymer donor and the low absorption of the fullerene acceptor in the visible spectral range.
Density functional calculations of the reactions C[X.sub.3] radical + [C.sub.20][H.sub.20] (X = H, F, Cl, and Br) based on two pathways (H-displacement and H-abstraction from [C.sub.20][H.sub.20]) showed that C[H.sub.3] radical prefers H-abstraction from [C.sub.20][H.sub.20] while F-displacement is favorable for the reaction of C[F.sub.3] radical with the fullerene. Exothermic characters of H-abstraction with the lower potential barrier indicate that the H-abstraction would dominate the reaction C[Cl.sub.3.sup.*] + [C.sub.20][H.sub.20] while endothermic characters with high potential barrier heights for two reaction pathways of [C.sub.20][H.sub.20] with C[Br.sub.3.sup.*] indicate unfavorable thermodynamically and kinetically pathways for these reactions [3].

A fullerene with the same number of vertices and the same pattern of faces (right) has hexagons with angles that vary in a much narrower range, which forces the faces to warp and the cage to become pointy.
