Few concepts are as frequently used as aromaticity in the current chemical literature. 1 This
may be quantified by ca. 300 000 papers dealing with the aromatic properties of chemical …

In this critical review, we survey the wide range of chemical reactions that have been
confined within carbon nanotubes, particularly emphasising how the pairwise interactions …

In this handbook, the leading experts in the field presents important and fundamental
aspects of the organic and organometallic chemistry of fullerenes. Naturally they also cover …

HIGH-ENERGY cosmic rays (relativistic heavy nuclei) play an important role in heating
interstellar matter in the Milky Way1, 2, and they affect chemical abundances through …

In spite of their importance in fundamental and applied studies, the preparation of
endohedral fullerenes has relied on difficult-to-control physical methods. We report a four …

When buckminsterfullerene was discovered in 1985, 1 Kroto suggested that it could be “the
first example of a spherical aromatic molecule”. Later, at about the time when Krätschmer …

The two-volume Encyclopedia of Supramolecular Chemistry offers authoritative, centralized
information on a rapidly expanding interdisciplinary field. User-friendly and high-quality …

Proposed more than 60 years ago, the ring current model (RCM) is still widely used to
rationalize the peculiar magnetic properties of aromatic molecules at the turn of the century …

Aromaticity, 1 one of the most important concepts in chemistry, is confined not only to planar
twodimensional (2D) molecules but also can be extended to diverse structures of other …

The maximal spherical aromaticity of an icosahedral fullerene such as C202+ (see picture)
can only be achieved with 2 (N+ 1) 2 π electrons. There is clear evidence for this rule from …
