Photochromism: Molecules and Systems Heinz Durr, Henri Bouas-Laurent
Publisher: Elsevier Science

Fast andreversible photoinduced structural changes characteristic of photochromic materials are particularly interesting as they imply the use of molecular systems for all-optical switching. ISBN: 1316669939 | PDF | 696 pages | 31.69 MBThis book, Organic Photochromic and Thermochromic Compounds, is the fourth major treatise on photochromism involving organic molecules and derived systems. [CrossRef] [details] Farrugia, L. Wheaton has won a National Science Foundation grant to acquire a cutting-edge laser system that will advance the research of three Wheaton scientists and their students. Abstract: Photochromic diarylethenes (DAEs) are among the most promising molecular switching systems for future molecular electronics. This review Further development of these photo-switchable systems into practical applications as well as existing challenges are also discussed and put in prospect. Kazuya Mori, Yukihide Ishibashi, Hirohisa Matsuda, Syoji Ito, Yutaka The Roles of Molecular Structure and Effective Optical Symmetry in Evolving Dipolar Chromophoric Building Blocks to Potent Octopolar NLO Chromophores. (Photoactive cyclophanes 5) The 1H NMR (Figure 10 and Supporting Information p S2) and the 13C NMR spectra ( 52 distinct signals are observed, see Experimental) point to the absence of symmetry in the molecule. Molecular systems with integrated chemical reactivity and photochromic functions are potentially beneficial for the development of novel functional materials. Photochromism is simply defined as the light induced reversible change of colour. Photochromism: Molecules and Systems. One-Color Reversible Control of Photochromic Reactions in a Diarylethene Derivative: Three-photon Cyclization and Two-Photon Cycloreversion by Near IR Femtosecond Laser Pulse at 1.28 μm. Photochromic molecules can be loosely divided into two types: those that returnto their initial state at a rate dependent on the ambient temperature ("thermally reversible" photochromic materials), and those which are thermally stable, . Download Photochromism: Molecules and Systems. Photochromism: Molecules and Systems by Heinz Durr, Henri Bouas-Laurent. Inspired by their smart photo-switchable characteristics, a variety of light-driven functional materials have been exploited, such as ultrahigh-density optical data storage, molecular switches, logic gates, molecular wires, optic/electronic devices, sensors, bio-imaging and so on. The $255,865 grant from NSF's Major Research Instrumentation Buthelezi will use the new instrument in her investigations of host/guest interactions of photochromic molecules, which change color reversibly when exposed to light or heat. Reversible intramolecular photocycloaddition of a bis(9-anthrylbutadienyl)paracyclophane – an inverse photochromic system. [CrossRef] [details] Filarowski, A., Koll, A. The two stereo-isomers of such photochromic compounds represent the distinct states of a light-switchable digital molecular system (Fig.
