Discovery of spheroidal carbon clusters [1-7] in 1985 heralded a new era in the
understanding of forms and characterstics of ubiquitous carbon [6, 7]. These carbon clusters …

Thermal cyclization of 7, 10-diethynylfluoranthene (3) in the gas phase gives corannulene
(2), the smallest bowl-shaped polycyclic hydrocarbon fragment of C60 with fullerene-like …

Graphite-like nanostructures including nanotubes and encapsulated polyhedral particles
have been obtained by arcing hexagonal boron nitride (h-BN) and tantalum in a nitrogen …

Publisher Summary This chapter describes the pyrolysis of hydrocarbons. Acyclic saturated
hydrocarbons (alkanes or paraffins) are hydrocarbons with the general formula C n H 2n+ 2 …

In this paper, we confirm our earlier observations of fullerenes (C60 and C70) in the Allende
meteorite (Becker et al., 1994a, 1995). Fullerene C60 was also detected in two separate C …

The flash vacuum pyrolysis (FVP) technique is useful for preparing curved polycyclic
aromatic compounds (PAHs) and caged nanocarbon molecules, such as the well-known …

B3LYP/6-31G (d, p) electronic structure calculations are employed to elucidate the reaction
mechanisms for the conversion of the alternant C18H12 polycyclic aromatic hydrocarbon …

Concave hydrocarbons, such as 1 (C36H36), 4 (C60H60), 5 (C54H48), and 6 (C60H52),
represent three‐dimensionally clamped analogues of π‐prismands. They encapsulate small …

Abstract The C60 polyarenes 4, 5, 18 a, and 18 b have been synthesized from truxene by
triple alkylation at C5, C10, and C15 followed by a palladium‐catalyzed intramolecular …

Novel graphitic nanostructures (eg nanotubes, graphitic onions, polyhedral particles,
hemitoroidal nanotube caps and branched nanotubes) are produced by arcing graphite …
