Preface
Molecules are created by the covalent bonding of atoms. However, although
a molecule is created from a multitude of atoms, it behaves as an individual
entity. A vast number of molecules of different sizes and structures are known,
ranging from the simplest hydrogen molecule to high-molecular-weight man-
made polymers and sophisticated biological macromolecules such as proteins
and DNA. Indeed, all living matter, natural minerals and artificial materials,
however complex and numerous they are, are combinations of some of these
tens of millions of molecules. We may therefore be tempted to believe that the
structures and properties of these materials and compounds can be directly
related to those of the individual molecules that comprise them in a straight-
forward way. Unfortunately, this notion is not correct. However deeply we
understand the nature of individual molecules, this knowledge is not enough
to explain the structures and functions of materials and molecular assemblies
that are derived as a result of organizing individual molecules. This is partic-
ularly true with biological molecular systems that are derived from the spatial
and temporal organization of component molecules.
In this book we delve into the field of supramolecular chemistry, which
deals with supermolecules. A supermolecule in this sense can be defined as
a “molecule beyond a molecule” – a large and complex entity formed from
other molecules. The molecules that comprise the supermolecule interact with
each other via weak interactions such as hydrogen bonding, hydrophobic in-
teractions and coordination to form new entities with novel properties and
functionsthatcannotbededucedbyasimplesummationoftheproperties
of the individual molecules. This monograph is intended to convey the rele-
vance and fascination of the fast-growing field of supramolecular chemistry to
advanced undergraduate students, and to provide an overview of it to young
scientists and engineers. Readers will find that supramolecular chemistry is
associated with many attractive disciplines of chemistry, including molecular
recognition, molecular topology, self-organization, ultrathin films, molecular
devices and biomolecular systems. As described in Chap. 1, supramolecular
chemistry is still a very young field, and so it is difficult to predict its future, but
it has already secured a firm position in the chemical sciences. For example,
biotechnology and nanotechnology are expected to lead to technological revo-

lutions in near future that will dramatically affect our lifestyles and economies.
Supramolecular chemistry is an indispensable tool in these technologies.
This book was originally written as part of a series of Japanese chemistry
textbooks. The authors hope that this book be warmly accepted by English-
language readers as well.
