Book Description
Metal- Free Synthetic Organic Dyes is a comprehensive guide to the synthetic, organic dyes that are classified by their chemical structure. As synthetic dyes are playing an increasingly important role in modern life, with applications in both industry and scientific research, this book provides insights on the many research attempts that have been made to explore new photosensitizers in the development of dye sensitized solar cells (DSCs). These novel photosensitizers have incorporated, within their structure, different organic groups, such as coumarins, cyanines, hemicyanines, indolines, triphenylamines, bis(dimethylfluorenyl) aminophenyls, phenothiazines, tetrahydroquinolines, carbazoles, polyenes, fluorenes, and many others. This comprehensive resource contains color figures and schemes for each dye discussed, and is an invaluable resource for organic, inorganic and analytical chemists working in academia and industry. - Features a discussion of the synthesis of the new, high-value synthetic dyes and pigments and their applications and performance - Includes coverage of new photosensitizers and their role in the development of dye sensitized solar cells (DSCs) - Covers synthesis of the functional dyes that are ideal for applications in the dye and pigment industry, textiles, color science, solar energy materials and solar cells, biomedical sensors, advanced materials, structure and synthesis of materials, and more

Book Description
This latest volume in the series entitled Liquid Chromatography of Natural Pigments and Synthetic Dyes presents an overview of the latest developments in the field while critically evaluating this method of analysis and providing comparisons of the various liquid chromatographic separation techniques that are currently available. Natural pigments and synthetic dyes are extensively used in various fields of everyday life including food production, textile industry, paper production, agricultural practice and research and water science and technology. Besides their capacity for increasing the marketability of products, natural pigments have shown advantageous biological activity as antioxidants and anticancer agents. On the negative side, synthetic pigments have a significant impact on the environment and can cause adverse toxicological side effects. Both pigment classes exhibit considerable structural diversity. As the stability of the pigments against hydrolysis, oxidation and other environmental and technological conditions is markedly different, the exact determination of the pigment composition may help for the prediction of the shelf-life of products and the assessment of the influence of technological steps on the pigment fractions resulting in more consumer friend processing methods. Furthermore, the qualitative determination and identification of the pigments may contribute to the establishment of the provenance of the product. The unique separation capacity of liquid chromatographic (LC) techniques makes it a method of preference for the analysis of pigments in any complicated accompanying matrices.* an overview of the latest developments in the field* a critical evaluation of results from this form of analysis* a comparison of the various LC (liquid chromatographic) separation techniques* future trends in the LC analysis of pigments

Book Description
Today synthetic dyes are used extensively in the textile dyeing, paper printing, color photography, pharmaceuticals, food and drink, cosmetic and leather industries. As of now, over 100,000 different dyes are available, with an annual production of over 700,000 metric tons. These industries discharge an enormous amount of colored effluents into natural water bodies, with or without treatment. The textile industry alone discharges 280,000 tons of dyes every year, making it the largest contributor to colored effluent discharge. Although a variety of treatment technologies are available, including adsorption, chemical oxidation, precipitation, coagulation, filtration electrolysis and photodegradation, biological and microbiological methods employing activated sludge, pure cultures, microbial consortia and degradative enzymes are economically viable, effective and environmentally responsible options. As such, this book gathers review articles from international experts working on the microbial degradation of synthetic dyes, offering readers the latest information on the subject. It is intended as a quick reference guide for academics, scientists and industrialists around the world.

Book Description
The Chemistry of Synthetic Dyes, Volume IV is a critical assessment of patent literature and scientific journals on the synthesis and applications of synthetic dyes. This volume is composed of seven chapters, and begins with a discussion on the application of dyes in textile fibers and printing, as well as in dyeing industry. A chapter provides a general description of dyeing, other properties, and applications of basic dyes. These topics are followed by a survey of the classification and potential application of cationic dyes. Another chapter focuses on the synthesis and reaction mechanisms of cyanine dyes. The final chapters look into the principles and chemistry of the formation of images by oxidative coupling. These chapters also examine the general laws governing the photochemical processes of dyes and of other organic compounds; the photochemical reactions of dyes in solution; the light-fading of dyed textiles and other dyes substrates; and the effect of spectral sensitization and special photo-reactions of dyes. This book will prove useful to organic chemists and technologists who are concerned with the synthesis of dyes and their applications.

Book Description
The Chemistry of Synthetic Dyes, Volume VII covers the synthesis and application of dyes, fluorescent brightening agents, color and electronic states of organic molecules, photochemistry of dyes, and physical chemistry of dyeing. This book is organized into five chapters—sulfur dyes; Bunte salt dyes; state of dye in dyebath and substrate; kinetics, equilibrium, dye-fiber affinity, and mechanisms; and applications of synthetic dyes to biological problems. This compilation specifically discusses the sulfur dyes of known constitution, analysis of sulfur dyes, and chemistry of Bunte salts. The chemical modification of proteins and dyes as antibacterial and therapeutic agents is also treated. This volume is recommended for organic chemists and technologists interested in the synthesis of dyes and their applications.

Book Description
The Chemistry of Synthetic Dyes, Volume VII stresses the relation between the chemistry of synthetic dyes and their application properties. This book describes the dyes for leather, synthetic carotenoids as food colorants, and solvent dyes. The phenomenal progress made in transfer printing, which the first commercial process became available as recently as 1968, is also discussed. This text likewise considers the influence of structural factors on the lightfastness of dyed fibers and structures of dyes with their technical properties. This volume is a good reference for organic chemists and technologists working on the synthesis of dyes and their applications.
