ABSTRACT
Since the discovery of C60 in 1985 and the paper on “Helical
microtubules of graphitic carbon” in 1991, research into carbon
nanotechnology has undergone a tremendous boom. As a result, a
vast number of new carbon nanoforms have been identified, studied,
and reported. Carbon nanostructures can range from structurally
well-defined molecules to larger “macromolecules” of which the
atomic arrangement cannot be described precisely. This chapter
gives a comprehensive summary of different sp2 and quasi-sp2
carbon nanoforms, with special emphasis on their topology and
morphology. We discuss briefly their various synthesis conditions
and potential applications.
