Book Synopsis New Frontiers in Photochromism by : Masahiro Irie
Download or read book New Frontiers in Photochromism written by Masahiro Irie and published by Springer Science & Business Media. This book was released on 2013-05-27 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochromism is the reversible phototransformation of a chemical species between two forms having different absorption spectra. During the phototransformation not only the absorption spectra but also various physicochemical properties change, such as the refractive index, dielectric constant, oxidation/reduction potential, and geometrical structure. The property changes can be applied to photonic equipment such as erasable memory media, photo-optical switch components, and display devices. This book compiles the accomplishments of the research project titled “New Frontiers in Photochromism” supported by the Ministry of Education, Culture, Sports, Science and Technology of Japan. The project focused not only on the above-mentioned classical subjects in photochromism, such as color changes, optical memory, and optical switches, but also on fundamental physicochemical studies and unprecedented application fields that have not yet been explored in photochromism. The latter topics include light-driven mechanical motion, photocontrol of surface wettability, metal deposition on solid materials, photocontrol of chiral properties, ultrafast decoloration dyes, and femtosecond laser experiments, among others.
Book Synopsis Photochromism: Molecules and Systems by : Heinz Dürr
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.

Book Synopsis Applied Photochromic Polymer Systems by : C.B. McArdle
Download or read book Applied Photochromic Polymer Systems written by C.B. McArdle and published by Springer. This book was released on 2012-11-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochromic polymer systems are of two main types: those which are merely solid solutions of photochromes in polymeric matrices and those custom-designed polymers which inherently exhibit photochromism. This book provides a concise review of developments in such systems over the past two decades. The coverage has been limited specifically to applied sys tems, or areas with potential applications, although over 500 references cite much of the literature on the fundamentals of the subject. In general, non-biological organic photochromism in organic matrices has been covered. However, the unique properties of polysiloxanes merit special mention in Chapter 4, because of the attributes that such inorganic polymers can provide in certain systems such as liquid crystalline photochromic polymers, where two extremely interesting phenomena are combined. In addition to outlets in polarization-sensitive holographic recording media, such materials exhibit interesting non-linear optical effects suitable for optical switching and rheo-optical phenomena which may find application in mechano-optic transduction. Within this framework examples of all the important photochromic mechanisms are covered by authors from both the industrial and the academic sectors. Given the photonic nature of the phenomenon under discussion, it is not surprising that many optical applications have been proposed. It is perhaps more surprising, however, that, until recently, no large scale markets had been identified that could commercially exploit photochromic phenomena.
