During the past few years there has been intense research activity in the design, synthesis, and characterization of materials which are formed from molecular precursors, and which have high or metal-like electrical conductivities, i.e. dcr/dT < O. It has been widely supposed that these new materials, which are commonly called molecular metals, would be pressed into service, for example as devices. Up to now, widespread, practical applications of these sub­ stances have not developed. The NATO Advanced Research Institute on Molecular Metals at Les Arcs, France, September 10-16, 1978 was organized to discuss the scientific and technological potential of research and development in this field. The proceedings of the Institute constitute this book. Several lectures were devoted to the assessment of the present status of research on systems which serve to define major components of the field. The systems which were discussed included TTF-TCNQ, platinum chain compounds, (SN)x, polyacetylene, polydiacetylene, graphite intercalation compounds, and mercury chain compounds. One lecture dealt with the status and potential of techriological applica­ tions of molecular, semiconducting and metallic materials. Texts accompanying these lectures are included in the book. In addition to the lectures, poster presentations of new results were held; these papers are also included here.
