Photochemistry Of Macromolecules

Our knowledge of the photodegradation of polymers, chemical evolution, photosynthesis, visual perception and the biological effects of light depends heavily on our ability to elucidate the primary photochemical processes of macromolecules. This volume brings together for the first time from the fields of natural as well as synthetic polymers a group of reports dealing with macromolecular photochemistry. Since macromolecular photo chemistry is an expanding new field that crosses the boundaries between classical disciplines, the reader will encounter the employment of diverse scientific approaches and unfamiliar terminology. However, it has become increasingly apparent that researchers in these fields have much to learn from each other. Although this book is not intended to give a detailed survey of the photochemistry of macromolecules. it does represent the editor's perspective on the relationship between theory, kinetic studies and the synthesis aspects of photochemistry. The ideas expressed by the contributors offer a valuable com posite of theoretical and experimental approaches for those who are concerned with problems which have photochemical relevance, and show that investigators from different fields share many concepts and perhaps some common problems. This novel array of present knowledge should provide a basis for organizing and understanding photochemical information from chemistry, physics, biology and medicine. While of particular value to the research worker, the book also should be of interest to the graduate student about to embark on a problem in macromolecular photo chemistry.

Metal- and metalloid-containing macromolecules are defined as large molecules (i.e., polymers, DNA, proteins) that contain a metal or metalloid group affiliated with the molecule. This volume describes what is possible with metal-containing polymers where the metal is an essential ingredient in obtaining desired optical and electronic properties. Covering applications in nonlinear optical materials, solar cells, light-emitting diodes, photovoltaic cells, field-effect transistors, chemosensing devices, and biosensing devices, this indispensible guide focuses on the photochemistry and photophysics of metal-containing polymers, with chapters by leading contributors to the core advances in this field.

Photochemistry of Proteins and Nucleic Acids focuses on the effects of ultraviolet and visible radiations on proteins and nucleic acids. The book first discusses some principles of photochemistry, including the laws of photochemistry and factors influencing photochemical reactions in solutions. The text describes absorption and luminescence spectra of nucleoproteins and their components, including principal absorbing groups in proteins, nucleic acids, and nucleoproteins. The selection also highlights the action of ultraviolet light on proteins; photochemical and photosensitized inactivation of enzymes; and the photochemistry of purine and pyrimidine derivatives. The text also discusses nucleic acids and oligo- and polynucleotides. Topics include photochemical degradation of nucleic acid; kinetics of biological inactivation of nucleic acids; nucleoproteins; and reversibility of nucleic acid photolysis. The book also encompasses the inactivation of viruses, including inactivation studies with a plant virus, bacteriophages, and photochemically produced vaccines. The text also presents some problems in photobiology and some techniques in photochemistry. The text is a good source of information for readers interested in the study of proteins and nucleic acids. Based on the standards and codes from Fo

A description of applications to electrical conductors, nonlinear optical devices, polymer light-omitting diodes (LEDs), electronic devices, batteries, antistatic coatings, and transistors. It reviews cases of metal-organic polymers incorporated with traditional organic polymers; assesses key properties of conjugated polymers; discusses features of

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.

Reviewing photo-induced processes that have relevance to a wide-ranging number of academic and commercial disciplines and interests covering chemistry, physics, biology and technology, this series is essential reading for anyone wishing to keep abreast of the current literature. Now in its 42nd volume, and with contributions from across the globe, this series continues to present an accessible digest of current opinion and research in all aspects of photochemistry. Topics covered in this volume include the state of the art in computational photochemistry, advances in dye sensitized photopolymerization processes, photoclick chemistry, and continuous flow photochemical reactions. This Specialist Periodical Report presents critical and comprehensive reviews of the last 12 months of the primary literature (drawing on 100's of citations) and is an essential resource for anyone working at the cutting edge of photochemistry and a gateway to newcomers in the field.
