Porphyrins, composed of four pyrrole subunits, are highly important compounds, which are ubiquitous in biological systems. This book reviews the factors that influence physical and chemical properties of tetrapyrrole species and explores the ways to tune geometric and electronic structures of porphyrins in order to modify their electronic, optical and magnetic characteristics.

The Porphyrins, Volume V: Physical Chemistry, Part C explores the physical chemistry of porphyrins, their precursors, catabolic derivatives, and related compounds. The book covers photochemical, electrochemical, and routes of electron transfer, as well as primary redox reactions of porphyrins and metalloporphyrins; oxygenation of hemoglobin and the interactions of metalloporphyrins with dioxygen; the kinetics of porphyrin metalation; and solid state phenomena. This volume is organized into 11 chapters and begins with an overview of electron transfer and the mechanisms of oxidation and reduction. The discussion then turns to porphyrin photochemical reactions and reversible electron transfer reactions of metalloporphyrins. Selected examples in which the oxidized or reduced complexes have been shown to play a biochemical role are provided. The following chapters focus on the isolation and characterization of the photosynthetic pigments and their aggregation and coordination properties, along with those of the porphyrins and metalloporphyrins. The book concludes with an analysis of solid state phenomena in porphyrins and related materials, paying particular attention to semiconduction, photoconduction, and superconduction. This book will be of value to inorganic, organic, physical, and biochemists interested in the physical chemistry of porphyrins.

The Porphyrins, Volume IV: Physical Chemistry, Part B focuses on the physical chemistry of porphyrins, their precursors, catabolic derivatives, and related compounds. The book covers nuclear magnetic resonance (NMR) spectroscopy of diamagnetic and paramagnetic porphyrins and electron nuclear double resonance (ENDOR) spectroscopy of chlorophylls and related systems. It also encompasses electron spin resonance (ESR) spectroscopy of porphyrin pi cations and anions, porphyrin excited states, metalloporphyrins, hemoproteins, and hemes. This volume is organized into nine chapters and begins with an overview of NMR theory and the use of NMR spectroscopy to study diamagnetic porphyrins and paramagnetic metalloporphyrins. The discussion then shifts to the theory of ENDOR spectroscopy and the application of ENDOR spectroscopy to analysis of chlorophylls, ESR of pi cations and anions of porphyrins as well as porphyrin excited states, and electron paramagnetic resonance and Mossbauer spectra of hemoproteins. The reader is also introduced to ESR and the electronic structure of metalloporphyrins. A chapter on Mossbauer spectroscopy of iron porphyrins concludes the book. This book is a valuable resource for inorganic, organic, physical, and biochemists interested in the physical chemistry of porphyrins.

The Porphyrins, Volume I: Structure and Synthesis, Part Ais the first in a series of seven volumes and covers topics like nomenclature, purification, and structural determination of porphyrins, metalloporphyrins, and other related compounds. This volume serves to be a critical review of the topics covered and presents a complete and comprehensible discussion on the chemistry and biochemistry of porphyrins. The chapters in the text tackle the history and geochemistry of porphyrins and related systems. Also covered and discussed in the chapters is the synthesis of porphyrins from mono-, di-, and tetrapyrrolic intermediates. The isolation and modification of porphyrins from natural sources are also discussed. Other related compounds are also included, such as metallo-, aza-, and N-methylporphyrins, and their synthesis and properties. This book is a good introduction and reference for students studying in the fields of chemistry and biochemistry.

Oxidative catalysis by metalloporphyrin systems occupies a prominent role in the current research in the fields of chemical and biological catalysis. Our particular interest and approach has been to collect in the same volume papers dealing with both the chemical and biological aspects of the reactivity of heme systems because of the realization that a better understanding of the complementary discipline can be extremely useful for the researchers from either field. The current progress of the research on synthetic metalloporphyrin catalysts has led to the development of several systems that are able to reproduce the heme-enzyme mediated oxygenation and oxidation reactions, at least in terms of reaction types, mechanisms and often rates. These achievements have stimulated the of creating metalloporphyrin catalysts which are both ambitious project efficient and stable enough to become competitive for large-scale industrial processes. Although this project is still far from being realized, the efforts in this direction parallel those aimed at the application of heme enzymes to chemical technologies, e. g. for the mild, selective oxidation of organics or the detoxification of pollutants. Both the two approaches will be advantageous because while the enzyme systems can achieve selectivities which are probably unattainable by synthetic catalysts, the latter can be active under experimental conditions that would readily inactivate the enzymes.

The Porphyrins, Volume III: Physical Chemistry, Part A deals with the physical chemistry of porphyrins, their precursors, catabolic derivatives, and related systems. The book covers electronic structure and spectroscopy including circular dichroism and magnetic circular dichroism as well as electronic, infrared, resonance Raman, and Zeeman spectroscopy. Porphyrin stereochemistry, X-ray crystallography, and mass spectroscopy are also included. This volume is organized into 12 chapters and begins with an overview of the optical absorption and emission spectra of porphyrins and the theory by which these facts are understood. The discussion then shifts to the electronic states of the iron porphyrin complex in various heme proteins as displayed by the light absorption properties in the visible region of the electromagnetic spectrum. The reader is methodically introduced to the electronic absorption spectra and molecular orbital theory of chlorophylls, the magnetic optical activity of porphyrins and hemoproteins, and circular dichroism studies of hemoproteins. The book also examines the mass spectra and infrared spectroscopy of porphyrins, resonance Raman scattering from metalloporphyrins and hemoproteins, and photographic essay of porphyrins and related macrocycles. It then concludes with a chapter on high-resolution Zeeman spectroscopy of metalloporphyrins. This book should be useful to inorganic, organic, physical, and biochemists interested in the physical chemistry of porphyrins.

The Porphyrins, Volume II: Structure and Synthesis, Part B is devoted to the structure and synthesis of porphyrins, their precursors, catabolic derivatives, and related systems. The book also covers nomenclature, history, geochemistry, purification, and structural determination of porphyrins, metalloporphyrins, and mono- and polypyrrolic compounds. This volume is organized into 10 chapters and begins with an overview of hydroporphyrins, paying particular attention to their synthesis and stereochemistry as well as reactivity, spectroscopy, and analogues. This book then discusses the synthesis, properties, thermodynamic stability, and evolution of porphyrinogens. The following chapters focus on porphyrins reversibly modified at the periphery by oxidation (oxophlorins) and by irreversible reactions at the periphery. The synthesis of photoexcited porphyrins, metalloporphyrins, and chlorophylls is covered. In addition, chapters on linear polypyrroles, their metal complexes, and macrocycles other than porphyrins are included. This book should be useful to inorganic, organic, physical, and biochemists interested in porphyrin chemistry and biochemistry.
