Available in PDF, EPUB and Kindle. Book excerpt: Only a small part of the numerous photochemical reactions in organic compounds result in reversible structural changes. The latter are accom panied by a change in physical properties, in particular, of electronic spectra. It is tempting to try to use this photochromic effect in various systems for controlling and regulating light fluxes and for data recording. Eventually an independent trend emerged in photochemistry - the study of the photochromism of organic compounds to establish relationships between structure and photochemical behavior, the theoretical analysis of these relationships to predict structures with pre-set photochromic parameters, and, finally, the identification of suitable areas for the application of photochromism. This monograph summarizes the results of recent studies carried out by a number of research institutions in the USSR and the GDR. Devoted to an important aspect of applied photochemistry, this monograph contains a detailed exposition of the chemical photochromes referred to briefly in the earlier editions of "Introduction to the Photochemistry of Organic Compounds" (Khimiya Press, Moscow, 1976) and "Photochemical Proces ses in Layers" (Khimiya Press, Moscow, 1978).

Download or read book Comprehensive Inorganic Chemistry II written by and published by Newnes. This book was released on 2013-07-23 with total page 7694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973
Download or read book Biomolecular Electronics written by Nikolai Vsevolodov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties of materials depend on the nature of the macromolecules, small molecules and inorganic components and the interfaces and interactions between them. Polymer chemistry and physics, and inorganic phase structure and density are major factors that influence the performance of materials. In addition, molecular recognition, organic-inorganic interfaces and many other types of interactions among components are key issues in determining the properties of materials for a wide range of applications. Materials require ments are becoming more and more specialized to meet increasingly demand ing needs, from specific environmental stresses to high performance or biomedical applications such as matrices for controlled release tissue scaf folds. One approach to meet these performance criteria is to achieve better control over the tailoring of the components and their interactions that govern the material properties. This goal is driving a great deal of ongoing research in material science laboratories. In addition, control at the molecular level of interactions between these components is a key in many instances in order to reach this goal since traditional approaches used to glue, stitch or fasten parts together can no longer suffice at these new levels of manipulation to achieve higher performance. In many cases, molecular recognition and self-assembly must begin to drive these processes to achieve the levels of control desired. This same need for improved performance has driven Nature over millenia to attain higher and higher complexity.

Download or read book Photochromism Molecules and Systems written by Heinz Dürr and published by Elsevier. This book was released on 2003-03-12 with total page 1221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochromism is simply defined as the light induced reversible change of colour. The field has developed rapidly during the past decade as a result of attempts to improve the established materials and to discover new devices for applications.As photochromism bridges molecular, supramolecular and solid state chemistry, as well as organic, inorganic and physical chemistry, such a treatment requires a multidisciplinary approach and a broad presentation. The first edition (1990) provided an enormous amount of new concepts and data, such as the presentation of main families based on the pericyclic reaction mechanism, the review of new families, some bimolecular photocycloadditions and some promising systems. This new edition provides an efficient entry into this flourishing field, with the core content retained from the original work to provide a basic introduction into the different subjects. *Second edition of a work first published in 1990, now revised due to constant development of research. *Including updated lists of references (1989-2001), offering immediate access to recent developments.*Providing great basic interest and high application potential bringing scientists together from chemistry, physics and engineering.
Download or read book Chromic Phenomena 3rd Edition written by Peter Bamfield and published by Royal Society of Chemistry. This book was released on 2018-08-24 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromic or colour related phenomena are produced in response to a chemical or physical stimulus. This new edition will update the information on all those areas where chemicals or materials interact with light to produce colour, a colour change, or luminescence especially in the imaging, analysis, lighting and display areas. The book has been restructured to show greater emphasis on applications where 'coloured' compounds are used to transfer energy or manipulate light in some way therefore reducing the details on classical dyes and pigments. In the past eight years, since the previous edition, there has been a remarkable increase in the number of papers and reviews being produced reflecting the growth of interest in this area. This ongoing research interest is matched by a large number of new technological applications gaining commercial value covering e.g. biomedical areas, energy, data storage, physical colour, bio-inspired materials and photonics. This book appeals to industrial chemists, professionals, postgraduates and as high level recommended reading for colour technology courses.

Download or read book Esipt Photochromism written by Mikhail Knyazhanskiy and published by Xlibris Corporation. This book was released on 2018-10-31 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: The photochromic anils (Imines of o-hydroxy aldehydes) have been found in the beginning of the last century, and therefore the views of this phenomenon were developing, along with theory of the structure and reaction mechanism and the methods of their investigations. The description of this development has been given shortly in the chapter one. The structure of anils, their properties, and their modifications in dependence of the substituents, solvents, and temperature are described, and solvatochromism and thermochromism are discussed in chapter two, along with hypothesis about mechanisms of these phenomena, which have been presented and based. The photochromic process in anil molecules has been discussed in detail in chapter 3. It is examined by stages, beginning from the very fast ESIPT (primary step) via the structural transformations in the excited states, generation in consecutive order of the fluorescence state with Anomalous (large) Stokes Shift (ASS flu), the twisted TICT-like precursory structure, and the twisted “post TICT” “colored” form in the ground state. The reverse reaction goes via the ground state or the excited state of the colored structure and the ground state proton transfer reaction (GSIPT). The post-TICT hypothesis is based on experimental data and quantum-chemical calculations. The photochromism of the bimolecular structures on the base of anil molecule is discussed in chapter 4 with assumption of interactions of the molecular fragments in the ground and the excited states. A lot of the photochromic systems with the Intramolecular H-bond and ESIPT and without anil molecules (about twenty types of the structures) have been discussed on the base of phenomenological classification of the photochromic properties (chapter 5). The brief consideration of the possible applications, including utilization of the perspective nanostructures as switchers, has been conducted in chapter 6. The material of the book can be used by the researchers, instructors, lecturers, and the students of various levels who work in the area of the reversible photochemical reactions, including photochromism.
