Iron Porphyrins

FUNDAMENTALS OF PORPHYRIN CHEMISTRY An indispensable and concise overview of the chemistry of porphyrins and related molecules In Fundamentals of Porphyrin Chemistry: A 21st Century Approach, a team of distinguished researchers delivers a compact and accessible introduction to the broad field of porphyrin chemistry. It discusses the basics of porphyrin synthesis and structure, as well as that of related molecules, and the current and future roles that porphyrins play in chemical transformations, materials design and synthesis, energy capture and transduction, human health, and the environment. This edited volume is a self-contained tutorial on concepts of critical importance to porphyrin chemistry and serves as the foundation for discussions about the applications of porphyrin-related compounds found in the second volume. This book contains: A thorough introduction to porphyrins, including their structure, nomenclature, naturally occurring porphyrins, synthetic porphyrins, and common families of porphyrin-related compounds Comprehensive explorations of chemical porphyrin synthesis, including how to synthesize porphyrins from simple, symmetric, and advanced ABCD-substituted porphyrins Practical discussions of the physical characteristics of porphyrins, including their structural features, electronic structure, spectroscopy, magnetism, electrochemistry, and electron transfer processes Perfect for experienced academic researchers in the field of porphyrin chemistry seeking a quick reference, Fundamentals of Porphyrin Chemistry: A 21st Century Approach is also an indispensable resource for researchers new to the field who need an overview directing them to literature in more focused areas.

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.

Scientists in such fields as mathematics, physics, chemistry, biochemistry, biology, and medicine are currently involved in investigations of porphyrins and their numerous analogues and derivatives. Porphyrins are being used as platforms for the study of theoretical principles, as catalysts, as drugs, as electronic devices, and as spectroscopic probes in biology and medicine. The need for an up-to-date and authoritative treatise on the porphyrin system has met with universal acclaim amongst scientists and investigators.

Porphyrins play a vital role in many biological functions including oxygen transport, electron transfer and catalyzing the incorporation of oxygen into other molecules. This current survey discusses the use of modern physical techniques to probe porphyrin structure and function. The authors review the data available through a particular technique and show what can be learned therefrom about the (electronic) structure and function of biologically important porphyrins. The techniques include magnetic circular dichroism, X-ray absorption fine structure (EXAFS) and Mössbauer spectroscopies. All contributors are well known in their respective fields, enjoying world-wide reputation.

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.

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.
