Preface by Sir Harold W. Kroto, FRS Although the discovery of C60
is now almost 15 years old and the extraction occurred 60 nearly
ten years ago it is amazing that the range of spin-off research
still seems to expand without limits. The birth of the Fullerenes
has spawned fascinating research programmes in almost every area of
chemistry and physics and this monograph explores a particularly
interesting and important area - the behaviour of these pure carbon
cages in the presence of high-energy radiation. The C molecules
must also be in the space 60 between the stars (albeit in
quantities too small to detect at this time) as the conditions in
the atmospheres of some carbon stars appear to be almost identical
to the plasmas generated in the Kratschmer-Huffman system for
making C60. The conditions in space 60 are very varied as it is
pervaded by a plethora of high-energy particles (photons, cosmic
rays, etc.) and the chapters in this book discuss, among other
things, the response of C60 and various derivatives to probing by a
range of high-energy particles. Various fullerenes and fullerene
salts have been examined by positron annihilation techniques,
revealing details of their electronic and structural properties as
well as phase transition behaviour. Muons have been implanted to
enable mSR techniques to probe with high sensitivity the endohedral
electronic structures of fullerenes including those in
superconducting systems. Mossbauer spectroscopy can give valuable
information about the interactions in certain types of
organometallic complexes and in particular it can reveal the degree
of charge transfer in endohedral species. Nuclear
irradiation/radiochemical analytical techniques have been applied
resulting in information ranging widely from the stability of the
fullerene cage containing endohedral metal atoms in various
oxidation states to pharmaceutical studies of the distribution of
fullerenes in the internal organs of animals. Time resolved pulsed
radio lysis provides information at high sensitivity enabling
micromolar concentrations to be probed e.g. C60 in water in which
it is almost insoluble! Redox and rate constant measurements have
given useful information on photolytically generated radical ion
pairs involving a variety of fullerenes. Interesting accounts of
observations involving the production of rare gas endohedral
species by nuclear recoil have revealed information about the
recoil mechanism. From the first moment of its discovery the unique
cage structure of C60 initiated thoughts about the interesting
possibility of encapsulation of atoms and molecules. One
possibility that immediately suggested itself was the isolation of
chemically toxic radionuclides by encapsulation in the (supposedly
chemically innocuous) cage for pharmaceutical purposes. The
possibility of creating cages carrying a radioactive atom inside
the cage and moieties outside with molecular recognition
capabilities is a most exciting prospect and discussion is included
of some important first steps aimed at achieving this fascinating
breakthrough. Another problem dealt with in this monograph is the
effect of elemental impurities which has, as our studies progress,
become more and more a matter of concern and interest. Impurities
can have important effects on the observed physical and chemical
behaviour of fullerenes, especially when very sensitive probe
techniques are applied. This valuable book reviews some detailed
studies of fundamental properties of fullerenes, which are leading
to a deeper understanding of their behaviour in the presence of
high energy radiation. The information obtained already and that
which will be garnered in future studies of the kind described here
is an absolutely necessary prerequisite for success in
applications.
