Focusing on complex naturally-occurring and synthetic supramolecular arrays, this work describes the mechanism by which transition metal complexes bind to DNA and how the DNA scaffold modifies the photochemical and photophysical properties to bound complexes. It includes details of photoinduced electron transfer between intercalated molecules, and examines thermally and photochemically induced electron transfer in supramolecular assemblies consisting of inorganic molecular building blocks.
Comprehensive theoretical and experimental analysis of UV-radiation and low energy electron induced phenomena in nucleic acid bases (NABs) and base assemblies are presented in this book. NABs are highly photostable; the absorbed energy is dissipated in the form of ultrafast nonradiative decay. This book highlights the possible mechanisms of these phenomena which is important for all living species and discusses technical challenges in exploration of these processes.
Photochemistry and Photobiology of Nucleic Acids, Volume I: Chemistry covers the historical developments in the study of photobiology and photochemistry of nucleic acid components. This volume is divided into 12 chapters that deal with the isolation and characterization of ultraviolet photoproducts of pyrimidines. After briefly covering the concepts of photochemistry of nucleic acids, this volume goes on describing the UV-induced physical and chemical alterations in nucleic acid components, such as pyrimidines, purines, their nucleosides and nucleotides, and related compounds. Significant chap ...
Connects principles, processes, and experimental techniques with current research in the continuously expanding field of photochemistry and photophysics Photochemistry and Photophysics covers a wide spectrum of concepts in photochemistry and photophysics, introducing principles, processes, and experimental techniques, with a wealth of examples of current applications and research spanning natural photosynthesis, photomedicine, photochromism, luminescent sensors, energy conversion and storage, and sustainability issues. In this Second Edition, several chapters have been revised considerably and others have been almost entirely rewritten. A number of schemes and figures have been added, and the reference list at the end of each chapter has been extended and updated. Clearly structured, the first part of the text discusses the formation, properties, and reactivity of excited states of inorganic and organic molecules and supramolecular species, and the second part focuses on photochemical and photophysical processes in nature and artificial systems. Readers will learn how photochemical and photophysical processes can be exploited for novel, unusual, and unexpected applications. Written by world-renowned experts in the field, Photochemistry and Photophysics includes information on: Formation, electronic structure, properties, chemical reactivity, and radiative and nonradiative decay of electronically excited states Fundamental concepts and theoretical approaches concerning energy transfer and electron transfer Peculiar light absorption/emission spectra and the photochemical properties of the various families of organic molecules and metal complexes Equipment, techniques, procedures, and reference data concerning photochemical and photophysical experiments, including warnings to avoid mistakes and misinterpretations Relationships between photochemical, photophysical, and electrochemical properties of molecules that enable interconversion between light and chemical energy With an appropriate mix of introductory, intermediate, and advanced content, this is an ideal textbook resource for related undergraduate and postgraduate courses. The text is also valuable for scientists already active in photochemical and photophysical research who will find helpful suggestions to undertake novel scientific projects.
This review of the ways in which ultraviolet and visible light affect the nucleic acids includes changes caused by excitation of the nucleic acids themselves, as well as reactions caused by photoexcitation of other reagents in the presence of nucleic acids.
This annual review, the 50th volume in the series, provides critical analysis for anyone wanting to keep up to date with the literature on photochemistry and its applications. This essential volume combines reviews on the latest advances in photochemical research with specific topical highlights in the field. The volume starts with periodical reports of the recent literature on organic and computational aspects, including computational advances in photochemistry, chemiluminescence and dark photochemistry, organic aspects of photochemistry of alkenes, dienes and polyenes, aromatic compounds, oxygen-containing functions and those functions containing other heteroatoms, and finally a chapter on transition metal catalysis. Coverage continues in the second part with highlighted topics including photochemical tools for sensing and controlling biological processes, visible light driven enantioselective processes, photochemical formation of C–Chalcogen bonds, photoelectrocatalysis, photovoltaic techniques, photochemical activation of aryl chlorides, luminescent water-soluble systems and computational analyses of fluorescence absorption spectra. This volume will again include a third section entitled ‘SPR Lectures on Photochemistry’, providing examples for academic readers to introduce a photochemistry topic and precious help for students in photochemistry.
Key topics in this publication include semiconductor photochemistry and photoelectrochemistry, dye-sensitized solar cells and photocatalytic treatment of chemical waste. It discusses the commercialization and solar energy conversion of DSSC and the photocatalytic oxidation of air contaminants.
The first edition of The Science of Photobiology was published in 1977, and was the first textbook to cover all of the major areas of photobiology. The science of photobiology is currently divided into 14 subspecialty areas by the American Society for Photobiology. In this edition, however, the topics of phototechnology and spectroscopy have been com bined in a new chapter entitled "Photophysics." The other subspecialty areas remain the same, i.e., Photochemistry, Photosensitization, UV Radiation Effects, Environmental Photobiology, Photomedicine, Circadian Rhythms, Extraretinal Photoreception, Vision, Photomorphogenesis, Photomovement, Photosynthesis, and Bioluminescence. This book has been written as a textbook to introduce the science of photobiology to advanced undergraduate and graduate students. The chapters are written to provide a broad overview of each topic. They are designed to contain the amount of information that might be presented in a one-to two-hour general lecture. The references are not meant to be exhaustive, but key references are included to give students an entry into the literature. Frequently a more recent reference that reviews the literature will be cited rather than the first paper by the author making the original discovery. The chapters are not meant to be a repository of facts for research workers in the field, but rather are concerned with demon strating the importance of each specialty area of photobiology, and documenting its relevance to current and/or future problems of man.
Bioinorganic photochemistry is a rapidly evolving field integrating inorganic photochemistry with biological, medical and environmental sciences. The interactions of light with inorganic species in natural systems, and the applications in artificial systems of medical or environmental importance, form the basis of this challenging inter-disciplinary research area. Bioinorganic Photochemistry provides a comprehensive overview of the concepts and reactions fundamental to the field, illustrating important applications in biological, medical and environmental sciences. Topics covered include: Cosmic and environmental photochemistry Photochemistry of biologically relevant nanoassemblies Molecular aspects of photosynthesis Photoinduced electron transfer in biosystems Modern therapeutic strategies in photomedicine The book concludes with an outlook for the future of environmental protection, discussing emerging techniques in the field of pollution abatement, and the potential for bioinorganic photochemistry as a pathway to developing cheap, environmentally friendly sources of energy. Written as an authoritative guide for researchers involved in the development of bioinorganic photochemical processes, Bioinorganic Photochemistry is also accessible to scientists new to the field, and will be a key reference source for advanced courses in inorganic, and bioinorganic chemistry.
