This volume presents a sequence of articles which describe the theoretical treat ments of investigating the fundamental features in the electronic structures and properties of typical quasi-one-dimensional solids; organic conductor TTF-TCNQ, polyacetylene, metallic and superconducting polymer (SN)n and linear chain chal cogenides and halides of transition elements including NbSe3' The aim of this volume is not to present an exhaustive review but rather to touch on a selective class of problems which appear to be fundamental for typical quasi-one-dimensional solids. Thus the topics in this volume are rather confined to the key basic properties of quasi-one-dimensional systems. The quasi-one-dimensional solids are one of the most extensively investigated subjects in current physics, chemistry and materials science. These materials are unique in attracting a broad range of scientists, chemists, experimental and theore tical physicists, materials scientists and engineers. In 1954 Frohlich constructed a theory of superconductivity based on a one-dimensional model of moving charge density waves. In 1955 Peierls predicted that anyone-dimensional metal is unstable against the distortion of a periodic lattice so that a metal-nonmetal transition occurs at a certain temperature for a one-dimensional metal. According to these theories a gap is opened at the Fermi surfaces of one-dimensional conductors at low tempera tures and the charge density wave is created in connection with the occurrence of the gap.

The history of low dimensional conductors goes back to the prediction, more than forty years ago, by Peierls, of the instability of a one dimensional metallic chain, leading to what is known now as the charge density wave state. At the same time, Frohlich suggested that an "ideal" conductivity could be associated to the sliding of this charge density wave. Since then, several classes of compounds, including layered transition metal dichalcogenides, quasi one-dimensional organic conduc tors and transition metal tri- and tretrachalcogenides have been extensively studied. The molybdenum bronzes or oxides have been discovered or rediscovered as low dimensional conductors in this last decade. A considerable amount of work has now been performed on this subject and it was time to collect some review papers in a single book. Although this book is focused on the molybdenum bronzes and oxides, it has a far more general interest in the field of low dimensional conductors, since several of the molybdenum compounds provide, from our point of view, model systems. This is the case for the quasi one-dimensional blue bronze, especially due to the availability of good quality large single crystals. This book is intended for scientists belonging to the fields of solid state physics and chemistry as well as materials science. It should especially be useful to many graduate students involved in low dimensional oxides. It has been written by recognized specialists of low dimensional systems.

The field of low-dimensional conductors has been very active for more than twenty years. It has grown continuously and both the inorganic and organic materials have remark able properties, such as charge and spin density waves and superconductivity. The discovery of superconductivity at high temperature in copper-based quasi two-dimensional conducting oxides nearly ten years ago has further enlarged the field and stimulated new research on inorganic conductors. It was obviously impossible to cover such a broad field in a ten day Institute and it seemed pertinent to concentrate on inorganic conductors, excluding the high Tc superconducting oxides. In this context, it was highly desirable to include both physics and chemistry in the same Institute in order to tighten or in some cases to establish links between physicists and chemists. This Advanced Study Institute is the continuation of a series of similar ones which have taken place every few years since 1974. 73 participants coming from 13 countries have taken part in this School at the beautiful site of the Centre de Physique des Houches in the Mont-Blanc mountain range. The scientific programme included more than forty lectures and seminars, two poster sessions and ten short talks. Several discussion sessions were organized for the evenings, one on New Materials, one on New Topics and one on the special problem of the Fermi and Luttinger liquids. The scientific activity was kept high from the beginning to the end of the Institute.

The present volume is the first of a series describing acyclic sulfur-nitrogen compounds with sulfur of oxidation number IV. The acyclic sw-N compounds are arranged according to the coordination number of the sulfur. Neutral compounds are described before ions and complex compounds. The preceding series "Sulfur-Nitrogen Compounds" Parts 2, 3, and 4 covers the cyclic sw-N compounds. In this volume, the first section deals with sulfur-nitrogen compounds with 1-coordinate sulfur and begins with the sulfur nitride {thiazyl) radical, SN. This transient molecule was observed in its electronic ground state and several electronically excited states. The descrip tions of the sulfur nitride (thiazyl) ions SN+ and SW follow. The SN+ ionwas studied in the gas phase as weil as in the solid state where it forms salts. Thionitrosyl complexes containing the SN Iigand as a terminal linear unit are described at the end of the first section. The second section concerns Sulfur-nitrogen compounds with 2-coordinate sulfur and starts with the description of poly(sulfur nitride), (SNlx· The preparation, crystal structure, and metallic and superconducting properties of (SN)x, which were extensively studied, fill a !arge part of the volume. Halogen-modified poly(sulfur nitride) such as the widely studied (SNBr )x 04 and Na-modified poly(sulfur nitride) are dealt with in the following chapters.

1.1. THE DISCOVERY OF CARBYNE Yu.P. KUDRYA VTSEV A.N. Nesmeyanov Institute ofOrganoelement Compounds, Russian Academy of Sciences, 117813 Moscow, Russia Abstract - The history of the discovery of carbyne is briefly recalled. The existence of carbyne was first disclosed by Russian researchers in 1960. It was obtained for the first time via oxidative dehydropolycondensation of acetylene based on the Glaser coupling of ethynyl compounds. 1. Introduction The polymeric nature of carbon was first pointed out by Mendeleev. He wrote: "The molecules of coal, graphite, and diamond are very complicated, and carbon atoms exhibit the capability of binding one to another to form complex molecules in all compounds of carbon. None of the elements possesses an ability of complicating in such an extent as does carbon. There is still no basis to define the polymerization degree of the coal, graphite, or diamond molecules. One should believe, however that they contain en species, where 'n' is a large value" [IJ. Until the 1960s only two allotropic forms of carbon were known, viz., graphite and diamond, including their polymorphous modifications. For a long time 'amorphous carbon' was also included among the simple forms. Presently, however, the structure of amorphous and quasi-amorphous carbons (such as carbon blacks, soot, cokes, glassy carbon, etc.) is known to approach that of graphite to various degrees [2J.

The explosion in the scale of production of polymers has made our daily life more convenient during the past several decades, and caused serious discus sion on recycling and safety. During this time, many polymer researchers who have constructed new industries and new fields of science changed their interests to specialty polymers and some have moved to bioscience. On the other hand, the expected limitations of silicon devices, which are fundamen tal in the present semiconductor and personal computer world, have initiated much interest in the idea of molecular electronic devices. Based on this idea, ultrathin films with many functions were studied, but it is still difficult to use them in real information systems. In these studies, polymer scientists and solid state physicists collaborated with each other and the new field of conju gated materials, including charge-transfer-complexes, conjugated conductive materials and fullerenes, has grown. Here, optical properties are the main interest because new materials are necessary in the advanced information so ciety of the twenty first century. During the course of this development, the boundary between polymers and small organic molecules has become blurred, except for the synthetic chemists. This new field of science and engineering is growing and will propose new materials and new devices. The present book aims at a compact presentation of the principal con cepts in current polymeric and organic materials science and engineering.

Krätschmer and Huffman's revolutionary discovery of a new solid phase of carbon, solid C60, in 1990 opened the way to an entire new class of materials with physical properties so diverse that their richness has not yet been fully exploited. Moreover, as a by-product of fullerene research, carbon nanotubes were later identified, from which novel nanostructures originated that are currently fascinating materials scientists worldwide. Rivers of words have been written on both fullerenes and nanotubes, in the form of journal articles, conference proceedings and books. The present book offers, in a concise and self-contained manner, the basics of the science of these materials as well as detailed information on those aspects that have so far been better explored. Structural, electronic and dynamical properties are described as obtained from various measurements and state-of-the-art calculations. Their interrelation emerges as well as their possible dependence on, for example, preparation conditions or methods of investigation. By presenting and comparing data from different sources, experiment and theory, this book helps the reader to rapidly master the basic knowledge, to grasp important issues and critically discuss them. Ultimately, it aims to inspire him or her to find novel ways to approach still open questions. As such, this book is addressed to new researchers in the field as well as experts.
