Synopsis Solitons & Polarons in Conducting Polymers by : Lu Yu
Polyacetylence, (CH)x is the simplest conjugated polymer. Prestine polyacetylence is a good insulator, whereas its highly doped version exhibits metal-like electrical conductivity. This book gives a detailed introduction to this rapidly-developing field is given along with a collection of original papers. The main purpose is to help chemists and physicists grasp the main ideas and most important facts; an expert may also find it useful as a reference volume.

Synopsis Conjugated Conducting Polymers by : Helmut Kiess
This book reviews the current understanding of electronic, optical and magnetic properties of conjugated polymers in both the semiconducting and metallic states. It introduces in particular novel phenomena and concepts in these quasi one-dimensional materials that differ from the well-established concepts valid for crystalline semiconductors. After a brief introductory chapter, the second chapter presents basic theore tical concepts and treats in detail the various models for n-conjugated polymers and the computational methods required to derive observable quantities. Specific spatially localized structures, often referred to as solitons, polarons and bipolarons, result naturally from the interaction between n-electrons and lattice displacements. For a semi-quantitative understanding of the various measure ments, electron-electron interactions have to be incorporated in the models; this in turn makes the calculations rather complicated. The third chapter is devoted to the electrical properties of these materials. The high metallic conductivity achieved by doping gave rise to the expression conducting polymers, which is often used for such materials even when they are in their semiconducting or insulating state. Although conductivity is one of the most important features, the reader will learn how difficult it is to draw definite conclusions about the nature of the charge carriers and the microscopic transport mechanism solely from electrical measurements. Optical properties are discussed in the fourth chapter.

Synopsis Solitons and Polarons in Quasi-one Dimensional Conducting Polymers and Related Materials by :
In recent years it has become increasingly appreciated that fundamentally nonlinear excitations - solitons - play an essential role in an incredible variety of natural systems. These solitons, which frequently exhibit remarkable stability under interactions and perturbations, often dominate the transport, response, or structural properties of the systems in which they occur. In this article, we present an introduction to the solitons that occur in quasi-one-dimensional conducting polymers (synmetals) and related systems. The relevance of this subject to molecular electronic devices is twofold. First, many of these materials have molecular structures similar to possible prototype molecular switches. Second, to understand in detail how a molecular electronic device could work, it is essential to have a broad perspective on the nature of possible excitations in a variety of natural and synthetic molecular materials. 51 references.

Synopsis New Directions in Conductive Polymers by : Alan J. Heeger
Scientific accomplishments during the period of this contract were reported in the form of published papers. More generally, we contributed in an important way to the development of the field with important contributions in all aspects of current activity. To single out a few of these we note the following: Demonstration of the generic importance of nonlinear excitations in conducting polymers (Solitons, Polarons and Bipolarons); Demonstration of the importance of nonlinear excitations in conjugated polymers to the nonlinear optical properties of these polymers; Demonstration of the control of the band gap through molecular design; Demonstration that the concept developed for solid state materials can be generalized to conducting polymers in solution. A complete list of the Publications, Patents, Presentations, Honors, etc is included in the End-of-The-Year Reports which were submitted and are on file at ONR. (MJM).

Synopsis The Peierls Ground State, Solitons and Polarons in Ring-Containing Polymers by :
The report of doping of polyacetylene to form a highly conducting polymer opened the question concerning the nature of the electronic states of the polymer backbone that are formed upon charge transfer between the polymer and dopant backbone. Extensive study of polyacetylene has demonstrated that this system is a degenerate Peierls semiconductor with a bandgap introduced through bond alternation. Pernigraniline is a semiconductor analogous to trans- polyacetylene. However, it differs from polyacetylene in that the overlap between adjacent sites can be modulated by both changes in bond length and changes in ring torsion angle. It is shown that as a result of these two independent order parameters there are differing types of charge excitation possible on pernigraniline backbone, with both bond order excitations such as bond order solitons and ring torsion excitations such as ring torsion polarons possible. Recent photoexcitation spectroscopy studies have confirmed the presence of both bond order solitons and ring rotation polarons.
