There are a number of potential uses of fullerenes. One potential use of nanotubes is for field effect transistors. Nanotubes decorated with metal atoms have a great potential for hydrogen storage for fuel cells. A3C60 compounds where... 

Figure 1.20 illustrates the alternative sequence of displays for such cases, the example of a C720 fullerene cage formed as 6 x Ceo and 3 x C120 orbits with a decoration pattern corresponding to six different decoration elements xyzuvw i.e. six different atoms on six distinct positions on the C720 fullerene cage. 

Figure 2.21 Pairwise coalescence of the decorated decagons of the regular orbit of 111 from Figure 2.19 leading to the truncated icosahedron [column a] and the small rhombicosidodecahedron [column b]. Note that the truncated icosahedral structure is 3-valent and is the archetypal C q cage of fullerene chemistry.

As an example of chirality assignment, consider vertex decoration of the icosahedral [60]-fullerene. Here the vertices span... 

Nierengarten and co-workers have described a series of ligands based upon dendron functionalized phen ligands decorated with fullerenes such as and have reported detailed studies of energy and electron transfer processes in the [CUL2] complexes. " ...

As far as fullerenes decorated by a shell of metal atoms are concerned, which we refer to as exohedral fullerenes, we can identify several possibilities which maintain the full symmetry of the bare structure. For C6o, there are = 12 sites above the centers of the pentagons, 2 = 20 sites above the centers of the hexagons, 3 = 30 sites above the centers of the electron-rich bonds between neighboring pentagons, 4 = 60 sites above the C atoms, and ns = 60 sites above the electron-poor bonds of the pentagons. We can place metal atoms at any of these sets of sites to form a shell of... 

Xu et al. [78] have synthesized gold (Au)-silica nanorods with shell thickness of 0-10 nm incorporated into the bulk heterojunction of organic solar cell and observed that at optimal (1 wt. %) concentration, Au-silica nanorods with 5 nm shell thickness resulted in the highest power conversion efficiency of 8.29%. A 26% relative enhancement in PCE was observed for a low bandgap polymer fullerene bulk heterojunction (BHJ) device after incorporation of 1% weight ratio of Au-silica nanorods by Xu et al. [79]. A similar enhancement was found when Ag-silica NPs were introduced at the interface of the anode buffer layer and active layer of a polymer fullerene BHJ device by Choi et al. [80]. Yang et al. [81] have developed a novel hole transport layer (HTL) composed of ultrathin two-dimensional, molybdenum disulfide (M0S2) sheets decorated with 20 nm...
