Metal Free Synthetic Organic Dyes

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

Carbon-based photocatalysis has been considered as an economic, safe, renewable, and clean technology, for various applications. However, the pristine carbon material is usually restricted by unsatisfactory photocatalytic efficiency and practical applications due to the insufficient solar light absorption, the low-surface area, and the fast recombination of photogenerated electron-hole pairs. Various modification strategies, such as elemental and molecular doping, preparation of mesoporous carbon materials, and combination of conductive materials, are adopted to enhance the photocatalytic activity of carbon materials. In this book, we intend to describe the great potential of efficient and low-cost carbon-based materials in various realms, such as photodegradation of organic compounds, water splitting, and selective organic transformations.

Considered the definitive serial in the field of heterocyclic chemistry Serves as the go-to reference for organic chemists, polymer chemists and many biological scientists Provides the latest comprehensive reviews written by established authorities in the field Combines descriptive synthetic chemistry and mechanistic insight to enhance understanding of how chemistry drives the preparation and useful properties of heterocyclic compounds

This series provides information on the nature of dyes, their harmful effects, and dye degrading techniques. The first volume of this series presents a fundamental concept of dye degradation. The information on target-oriented dye mitigation is intended to give readers a better understanding of the dye degradation process to sustain a healthy environment. Chapters present referenced information and highlight novel breakthroughs in the industry. Key topics: Foundations of Dye Knowledge: Evaluating Toxicity Nanotechnology Electrochemistry Catalytic Materials and Photocatalysis Microbial Biodegradation This book serves as a foundational resource for researchers and students in chemistry and chemical engineering courses. It also serves as a reference for industry professionals who work with chemical dyes (for example in textile and plastic industries) and are engaged in the critical field of environmental remediation. Readership Scholars in chemistry and chemical engineering; professionals in manufacturing industries and environmental sustainability. Series Intro This series provides information on the nature of dyes, their harmful effects, and dye degrading techniques. Each volume will bring a collection of edited topics on dye degradation. The goal of the series is to provide readers with detailed knowledge about dye degradation. The editors also aim to give a broad perspective on the role of dye remediation technologies in creating a sustainable environment.

In the ten years since publication of the second edition of Heinrich Zollinger's "Color Chemistry", significant trends in colorant research and application have become important. Particular emphasis is given to the discussion of the synthesis, properties, and application of pigments.

HANDBOOK of WATER POLLUTION Handbook of Water Pollution discusses a wide range of contaminants heavily affecting our environment and water bodies. The chapters discuss heavy metals, metalloids, pesticides, explosives, toxic chemicals, dyes, plastics, e-wastes, fertilizers, detergents, nitrates/nitrites, phosphates, hydrocarbons, and fecal wastes, along with their sources of action against our environment, their methods of analysis, and finally, their treatments are all presented in detail. Our environment is heavily affected due to extreme human activities. Environmental pollution is a major concern worldwide. Within this, water pollution is one of the major challenges that puts the total ecology at risk. Water pollution is alarming everywhere; many governing authorities believe it is also an unavoidable result of human activity. However, the economic cost of water pollution far outweighs the benefits of skimping on its cause. Water pollution is not just merely related to financial cost but related to all living beings. Toxic waste is getting into the water bodies in various regions, causing many illnesses in humans and poisoning other living things. The destruction of any single component of our ecosystem can have a devastating effect on our biodiversity. Therefore, it is necessary to understand the causes of pollution, their nature and mechanism, and, at the same time, study the remedies. The major causes of water pollution are industrial waste, sewage, plastics, oil leakage, biological organisms, toxic chemicals and radioactive waste, and so on. A tremendous amount of research work is going on around the world to understand the causes, their mechanism, and solutions. Many new works are published every day, therefore it’s important to gather some of the most relevant findings in one place. This will serve as a link between collected knowledge and current advancements, while also facilitating future thinking.

This book describes insight mechanisms for designing molecular probes and methods that these agents can be used for medical diagnosis in preclinical animal models via optical, MRI and PET imaging. The book has a wealth of schemes of synthesis and methods deduced from pioneers in the field, making it possible to immerse into real-world molecular imaging. Written for graduate student training and practitioners, this book will serve as a teaching material and/or reference for anyone interested in exploring the power of chemical synthesis of imaging agents.
