The hoped-for applications of fullerenes have not materialised as yet. A cartoon published in America soon after the discovery shows a hapless hero sinking into a vat full of buckyballs (another name for fullerenes) with their very low friction. It is not known how the hero managed to escape... 

SnCl2-2H20, CH2CI2, 2 h, 84-99% yield. The presence of the buckyball improves the yield. 

Buckminsterfullerene (Cm or Buckyball ) is structurally related to corannulene. In which molecule would you expect 7U-orbital overlap be more effective Explain. How many chemically unique carbons are there in C6o Measure CC bond distances. How many unique distances are there Is each benzene fully delocalized or is one resonance contributor more important than the other ... 

Bnckminsterfullerene (buckyball). (a) The arrangement of the 60 carbon atoms in a buckyball. (b) The identical arrangement of the hexagons and pentagons on the surface of a soccer ball.

The following sections discuss many of the major particle types and provide bioconjugation options for the coupling of ligands to the surface of functionalized particles. Some additional nanoparticle constructs, including gold particles, dendrimers, carbon nanotubes, Buckyballs and fullerenes, and quantum dots are discussed more fully elsewhere (see Chapter 7 Chapter 9, Section 10 Chapter 15 and Chapter 24). 

Figure 15.2 The structure of a Q 0 fullerene, also called a Buckyball.

There now are known to be a whole family of caged carbon structures having various numbers of carbon atoms, including C30, C50, C7o, C72, C76, Cg4, and the huge C540. The name fullerene has replaced the unwieldy, Buckminsterfullerene used to describe this general spheroid structure of carbon, although they still are referred to as Buckyballs .
