Available in PDF, EPUB and Kindle. Book excerpt: Although studies on synthetic dyes have been performed for more than 100 years, their detailed elucidation requires further extensive research. The discovery of novel high polymers, the necessity of supplying a whole range of shades and increasing require ments for dyestuffs of high fastness properties give rise to a permanent search for new dyes. Extensive investigations on dyes were also occasioned by various applications in the field of spectral sensitization and of staining of biological specimens. Another more recent development concerns the lasing properties of some organic dyes. Most of the progress, however, was only achieved by time-consuming, purely empirical approaches and theoretical understanding of the dye properties is only at its very beginnings. The color is the sine qua non of every dye. For this reason organic chemists and color chemists have looked for relations between the "color and constitution" of dye molecules for a long time. This knowlege as a whole is known as "theory of color". The classic theory of color was established abou t 100 years ago by Witt and was signi ficantly extended 50 years later by W. Konig.

This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The traditional use of organic colorants is to impart color to a substrate such as textiles, paper, plastics, and leather. However, in the last five years or so organic colorants have become increasingly important in the high technology (hi-tech) industries of electronics and particularly reprographics. In some of these reprographics applications the organic colorant is used in its traditional role of imparting color to a substrate, typically paper or plastic. Examples are dyes for ink-jet printing, thermally transferable dyes for thermal transfer printing, and dyes and pigments for colored toners in photocopiers and laser printers. In other applications it is a special effect of an organic colorant that is utilized, not its color. Examples are electrical effects, such as photoconduction and the electrostatic charging of toners, both of which are essential features for the operation of photocopiers and laser printers, and the selective absorption of infrared radiation, which is utilized in optical data storage. In electronic applications the organic colorant is often employed in a device. Typical examples include liquid crystal dyes, laser dyes, electro chromic dyes, dyes for solar cells, dyes for micro color filters, and dyes for nonlinear optical applications.

Available in PDF, EPUB and Kindle. Book excerpt: Optical transitions between the quasistatic energy states of a solute organic dye are described using the coherent-interaction formalism. Expressions for the polarization and occupation state of a single molecule are averaged statistically to obtain rate equations for the absorption of light by an ensemble of molecules. The formalism developed in this report is used to describe spectral hole burning in organic dyes, as well as to investigate beam distortion that may arise during nonlinear attenuation. The formalism also leads to analytic expressions for the shape of organic-dye absorption and refractive-index spectra in terms of fundamental molecular parameters. An experimentally oriented chapter contains a review of past work on saturable absorption, and a description of research carried out in this laboratory on the ruby-laser Q-switch dye DDI. (Author).

Book excerpt: In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications. They set the scene by explaining the reasons behind these differences and show how dyes are predominately organic compounds that dissolve or react with substrates, whereas pigments are (predominantly) finely ground inorganic substances that are insoluble and therefore have a different mode of coloring. They also describe the role of functional groups and their effect on dyeing ability, contrasting this with the way in which pigments cause surface reflection (or light absorption) depending on their chemical and crystalline structure and relative particle size. The book explores the environmental impact of dyes in a section that covers the physical, chemical, toxicological, and ecological properties of dyes and how these are used to assess their effect on the environment and to estimate whether a given product presents a potential hazard. Lastly, it assesses how, in addition to their traditional uses in the textile, leather, paper, paint and varnish industries, dyes and pigments are indispensable in other fields such as microelectronics, medical diagnostics, and in information recording techniques.

Available in PDF, EPUB and Kindle. Book excerpt: New laser technology has developed a new dye chemistry! Development of the gallium-arsenic semiconductor laser (diode laser) that emits laser light at 780-830 nm has made possible development of new opto-electronic systems including laser optical recording systems, thermal writing display systems, laser printing systems, and so on. Medical applications of lasers in photodynamic therapy for the treatment of cancer were also developed. In such systems, the infrared absorbing dyes OR dyes) are currently used as effective photoreceivers for diode lasers, and will become the key materials in high technology. At the present time the chemistry of IR dyes is the most important and interesting field in dye chemistry. Laser light can be highly monochromatic, very well collimated, coher ent, and, in some cases, extremely powerful. These characteristics make diode lasers a very cheap, convenient, and useful light source for a variety of applications in science and technology. For these purposes, however, IR dyes with special characteristics are required. To develop new IR dyes, it is most important to establish the correlation between the chemical structures of dyes and other characteristics of dyes, such as their absorption spectra. Molecular design of IR dyes predicting the Amax and Emax values by molecular orbital (MO) calculations is now possible even by using a personal computer, and many types of new IR dyes have been demonstrated. Also, new opto-electronic systems using IR dyes as photoreceivers have been reported recently.

Book excerpt: This book summarizes the results of the NATO Advanced Research Workshop on "Syntheses, Optical Properties, and Applications of Near-Infrared (NIR) Dyes in High Technology Fields" held at Trest (Czech Republic) from September 24 to 27, 1997. It was attended by 52 scientists from 16 countries, among them 18 participants from 8 Eastern-Europe. The Workshop has been stimulated by the great progress that has been made in utilizing NIR dyes in high technology areas. This has been triggered by the availability of reliable. vel)' small, and inexpensive laser diodes emitting in the NIR region which raise the analytical detection limits by several orders of magnitude, allow time-resolved measurements for temporal discrimination between spectrally similar species, and make possible miniaturization as well as remote sensing through space and by fiber optical techniques. Furthermore, NIR dyes proved to be vel)' important in other high technology fields such as laser physics, optical recording techniques, nonlinear optics, biochemistty and medicine.

Colour Chemistry then goes on to look at the structure and synthesis of the various dyes and pigments, along with their applications in the traditional areas of textiles, coatings and plastics, and also the ever-expanding range of "high-tech" applications. Also discussed are some of the environmental issues associated with the manufacture and use of colour. The broad and balanced coverage presented in this book makes it ideal for students and graduates. In addition, many specialists in industry or academia will also benefit from the overview of the subject that is provided.
