This book was released on 2005 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The final report describes studies over a 13 year period having to do with photoinduced electron transfer for active chromophores and redox agents, including assembly of the components in water soluble polymers or polypeptides. The findings include observation of long range charge separation and electron transport using laser phototransient spectroscopy. The systems targeted in these studies include peptide assemblies for which helical conformations and aggregation are documented. Oligomeric peptides modified with non-native redox active groups were also selected for investigation. Highly charged polymers or peptides were investigated as host agents that resemble proteins. The overall goal of these investigations focused on the design and characterization of systems capable of artificial photosynthesis.

Download or read book Heterogenous Photochemical Electron Transfer written by Michael Gratzel and published by CRC Press. This book was released on 2018-01-18 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph attempts to unify these diverse and exciting new developments within a common framework. First, the physical principles underlying heterogenous electron-transfer processes are outlined in a concise way and are compared to the homogeneous counterpart. This analysis includes the notion of the Fermi level in liquids and solids as well as the distribution of electronic energy levels in solids and liquids. A comparison is made between the salient kinetic features of homogeneous and heterogeneous electron transfer reactions. This establishes the basis for the subsequent treatment of the transduction of excitation energy and photo-initiated electron transfer in organized molecular assemblies, such as micelles, vesicles and monolayers. Transmembrane redox processes are critically reviewed. Particular attention is given to semiconductor electrodes and particles. This includes a discussion of quantum size effects, the nature of space charge layers as well as surface states and the dynamics of charge carrier-induced redox reactions at the semiconductor solution interface. These processes are of fundamental importance in such diverse fields as photochromism, electrochromic displays, electroreprography and photography, information storage, photocatalysis, photodegradation of paints, and solar energy conversion.

Book excerpt: Long range photoinduced electron transfer between electron donor and acceptor groups is of considerable current interest in terms of strategies for artificial photosynthesis and studies regarding the redox properties of proteins. As part of an extensive study of long range electron transfer involving biopolymers, we have carried out this year investigations of the assembly of electron transfer agents in a system of model short peptides. Also studied is a polyelectrolyte that can adopt a helical conformation when electrostatically complexed with organic dye counter-ions. The principal interest in these systems has to do with the well ordered secondary structures adopted by peptide polymers, and the capabilities for synthetic modification of peptide side chains and end groups with chromophores or electroactive substituents. The present report gives a brief account of the following elements of work related to photochemical electron transfer themes: (1) the synthesis and photochemical characterization of chromophore-bound peptides and amino acid model compounds based on the amino acids, tryptophan and the spacer residue, alanine (Ala); (2) the study of binding of the cationic organic dye to a peptide electrolyte, for which cooperative dye loading and helix formation is important; and (3) completion of the synthesis of a new series of acridinium chromophores that have rod-like'' arrangements of inked aryl rings for assembly of electron donor-acceptor systems that will exhibit especially long lived charge separation.
Book Synopsis Fundamentals of Photoinduced Electron Transfer by : Bertram H. Raven
Download or read book Fundamentals of Photoinduced Electron Transfer written by Bertram H. Raven and published by Wiley-VCH. This book was released on 1983-03 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Devoted exclusively to the basic theories, concepts and applications of light-initiated electron transfer processes, Fundamentals of Photoinduced Electron Transfer is the first book to deliver an introductory-level account of this highly active research area in a concise and easy-to-follow pedagogical manner. No prior knowledge of photochemistry is assumed or required. The author introduces essential background information on photochemistry and electrochemistry and presents a systematic account of the photoinduced electron transfer process. He carefully explains the fundamental thermodynamic equation governing the photoinduced electron, explores the diverse realm of electron photochemistry reactions and provides a survey of today's most important applications. Coverage also features discussion on classical and nonclassical theories to faster insight on a host of underlying molecular and environmental factors. Novel applications such as solar energy conversion, artificial photosynthesis, semiconductor technology, organized assemblies, and molecular electronic devices are described in appropriate detail. Fundamentals of Photoinduced Electron-Transfer is of special value as both a learning tool and working reference in photochemistry, physical chemistry, molecular physics, spectroscopy and electrochemistry.

Book Synopsis Effects of Light on Materials in Collections by : Terry T. Schaeffer
Download or read book Effects of Light on Materials in Collections written by Terry T. Schaeffer and published by Getty Publications. This book was released on 2001-08-16 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of light on works of art and archival materials has long been an issue of concern to conservators and other museum professionals, yet the literature on this subject has never been systematically reviewed. This volume fills that gap by providing a survey of the impact of exposure to light with an emphasis on photoflash and reprographic sources. The information provided will assist the professional audience, especially conservators and collections managers, in assessing the risk to art and archival objects of such exposures. The text surveys relevant photophysical and photochemical principles, photometric and radiometric measurement, and the spectral outputs of several light sources. Materials discussed include colorants and natural fibers; pulp, paper, and wood; natural and synthetic polymers; fluorescent whitening agents; photographic and reprographic materials; and objects containing combinations of materials. Approximations and assumptions used in the evaluation process are discussed in some detail, with examples of the different types of calculations. The Research in Conservation reference series presents the findings of research conducted by the Getty Conservation Institute and its individual and institutional research partners, as well as state-of-the-art reviews of conservation literature. Each volume covers a topic of current interest to conservators and conservation scientists.
