PREFACE

Polyoxometalates are discrete early transition metal-oxide cluster anions and comprise

a class of inorganic complexes of unrivaled versatility and structural variation in both

symmetry and size, with applications in many fields of science. Recent findings of both

electron-transfer processes and magnetic exchange-interactions in polyoxometalates with

increasing nuclearities, topologies, and dimensionalities, and with combinations of different

magnetic metal ions and/or organic moieties in the same lattice attract strong attention

towards the design of nano-composites, since the assemblies of metal-oxide lattices ranging

from insulators to superconductors form the basis of electronic devices and machines in

present-day industries. The editors organized the symposium, “Polyoxometalate Chemistry

for Nano-Composite Design” at the Pacifichem 2000 Congress, held in Honolulu on

December 17–19, 2000. Chemists from several international polyoxometalate research

groups discussed recent results, including: controlled self-organization processes for the

preparation of nano-composites; electronic interactions in magnetic mixed-valence

cryptands and coronands; synthesis of the novel polyoxometalates with topological or

biological significance; systematic investigations in acid-base and/or redox catalysis for

organic transformations; and electronic properties in materials science.

It became evident during the symposium that the rapidly growing field of

polyoxometalates has important properties pertinent to nano-composites. It is therefore easy

for polyoxometalate chemists to envisage a “bottom-up” approach for their design starting

from individual small-size molecules and moieties which possess their own functionalities

relevant to electronic/magnetic devices (ferromagnetism, semiconductivity, proton-

conductivity, and display), medicine (antitumoral, antiviral, and antimicrobacterial

activities), and catalysis. The resulting exchange of ideas in the symposium has served to

stimulate progress in numerous interdisciplinary areas of research: crystal physics and

chemistry, materials science, bioinorganic chemistry (biomineralization), and catalysis.

Each participant who contributed to this text highlights some of the more interesting and

important recent results and points out some of the directions and challenges of future

research for the controlled linking of simple (molecular) building blocks, a reaction with

which one can create mesoscopic cavities and display specifically desired properties. We

believe that this volume provides an overview of recent progress relating to

polyoxometalate chemistry, but we have deliberately chosen to exclude discussion of

infinite metal oxide assemblies.
