Electron transfer reactions are of great importance to nearly every subdiscipline of chemistry. The simple transfer of a single electron has been shown repeatedly to be a common activating mode for organic, inorganic, and biological molecules, and the very ubiquity of such reactions has guaranteed that their investigation would involve the most fundamental questions of modern chemistry. The fact that photoexcitation induces enhanced redox reactivity via electron transfer also provides a convenient method for experimentally testing theoretical predictions regarding structural and energetic effects. As can be seen from the very size of this work there is a great deal known about photoinduced electron transfer reactions and the editors have tried to capture the diversity and excitement inherent in this broad field. The reader will find contributions from theorists and experimentalists, from organic and inorganic chemists, from the perspective of the synthetic and mechanistic viewpoint. Some contributions are fundamental basic research, while others clearly show practical applications of these principles.These volumes are intended to serve a joint purpose: as a reference resource and an introductory overview to the diverse research accomplished via photoexcitation of electron donor-acceptor systems. The information is organized in four parts. The first deals with the theoretical and conceptual factors which influence electron transfer. The second covers experimental methodology and medium effects. The third and fourth deal with reactivity, with most organic transformation being addressed in Part C and most inorganic reactions covered in Part D. Each part thus provides an overview of typical reactions observed for these classes of compounds. Part D also provides examples of photoinduced electron transfer in current use in important applications. There is of course a significant interdependence between the four parts. Subject, chemical, and author citation indices appear at the end of each of Parts A, B and C, and comprehensive indices are included in Part D.

This book contains papers which examine fundamental aspects of photoinduced electron transfer reactions, an area in which a number of breakthroughs have recently occurred. The book is divided into four parts. Parts I and II are mainly concerned with the fundamental aspects of the inter- and intra-molecular charge transfer, electron transfer and related phenomena such as solvent effects, solvation dynamics, energy gap dependences and radical pair dynamics. Part III is concerned with electron transfer and energy transfer phenomena in polymers, films, crystals, and other confined systems. In Part IV, the mechanisms of the energy and electron transfer in biological photosynthetic systems, proteins and reaction center systems are discussed.

Chemical and Biological Generation of Excited States discusses major aspects of chemical and biological generation of electronic excitation. This book is organized into 11 chapters that focus on both chemi- and bioenergized processes. This book first discusses some of the fundamental aspects of the description of excited state behavior in condensed media. It then examines the field of gas-phase dioxetane chemiluminescence both by itself and in relation to solution-phase studies. The presented analysis is based on statistical mechanics and supported by a very simple limiting case calculation. Chapter 4 describes the state-of-the-art of how excitation yields are determined experimentally in chemienergized processes. This is followed by a discussion on activation parameters and stability trends, focusing on solution-phase data. Chapters 6 and 7 examine solution-phase chemiluminescence resulting from high-energy electron-transfer reaction, often involving aromatic radical ions, and the mechanism of excitation step. The next chapters cover the generation of electronic excited states in bioluminescence and the evaluation of luminescent oxidation mechanisms using oxygen tracers. The chapters also explain the formation of electronically excited products in dark biological processes and the mechanism of chemiexcitation as it relates to redox metabolism. Specific examples of biological oxygenation reactions yielding luminescence are also presented. Furthermore, this book discusses the concept and applicability of chemiluminigenic probing for the quantification and differentiation of oxygenation activities in mammalian phagocytes. The concluding chapter is devoted to the possible formation of singlet oxygen in various systems and processes that mimic singlet oxygen reactions. The book intends to attract young scientists as well as established research workers to broaden the horizons of this rapidly growing and potentially very important field.

Bridging the gap between the multitude of advanced research articles and the knowledge newcomers to the field are looking for, this is a timely and comprehensive monograph covering the interdisciplinary topic of intramolecular charge transfer (ICT). The book not only covers the fundamentals and physico-chemical background of the ICT process, but also places a special emphasis on the latest experimental and theoretical studies that have been undertaken to understand this process and discusses key technological applications. After outlining the discovery of ICT molecules, the authors go on to discuss several important substance classes. They present the latest techniques for studying the underlying processes and show the interplay between charge transfer and the surrounding medium. Examples taken from nonlinear optics, viscosity and polarity sensors, and organic electronics testify to the vast range of applications. The result is a unique information source for experimentalists as well as theoreticians, from postgraduate students to researchers.
