Book Description
Recent advances in computational chemistry have made it feasible to design many types of molecules and predict their properties theoretically. The author applied these techniques to the design of organometallic transition-metal dyes absorbing in the near-infrared region of the spectrum which possess the combination of a large molar extinction coefficient, good chemical and thermal stability, and a high solubility in liquid crystal (LC) hosts. These properties are required for the dye to function as a near-infrared (IR) attenuator in a liquid crystal point diffraction interferometer (LCPDI) device that will be used as a beam diagnostic on the 60-beam OMEGA solid-state Nd:glass laser system at the University of Rochester's Laboratory for Laser Energetics. Using commercially available software, both the absorption spectra and solubility characteristics of bis[1,2-di-(p-n alkoxyphenyl)ethane-1,2-dithione] nickel dye complexes were modeled in an isotropic host (cyclohexane) and, in most cases, excellent agreement was found with experimental data. Two additional compounds utilizing the same nickel dithiolene core but with alkylthio and phenylalkylthio terminal groups have been designed and show excellent potential to produce dramatic improvements in both solubility and optical density (absorbance) in liquid crystalline hosts. Based upon my work, a new dye not previously reported, 2(C4S)2(C4SPh)DTNi, has been proposed to satisfy the LCPDI device requirements. The nickel dithiolene dyes may also find important applications in other technology areas such as near-IR photography and laser-based near-IR communications.
Dianion Chemistry in Organic Synthesis
Author: Charles M. ThompsonPublisher: CRC Press
ISBN: 9780849378683
Category : Science
Languages : en
Pages : 264
Book Description
Many laboratories were reluctant at first to embrace dianion chemistry as part of the standard reaction repertoire. Today, however, researchers can comfortably draw upon the dianion literature to choose an abundance of reagents and strategies that are reliable, effective, and, in many cases, the best answer to a synthetic problem. This interesting book introduces, surveys, and consolidates carbon-based dianion chemistry. Chapter 1 serves as an introduction and as an index of the various dianions covered in the book. Chapters 2 through 5 cover the ensemble of dianion types designated by their first deprotonation site. Each chapter contains an experimental section that explains relevant protocols.
