Book Description
Since their initial accidental synthesis and characterization in Scotland in the late 1920s, there has been a strong research focus on the use of phthalocyanines (Pcs) as dyes and pigments. In recent years, active research fields have included their use in electrophotography, photovoltaic and solar cells, molecular electronics, Langmuir-Blodgett films, photosensitizers, electrochromic display devices, gas sensors, liquid crystals, low-dimensional conductors, and optical disks. Phthalocyanines possess interesting biological, electronic, optical, catalytic, and structural properties. The main disadvantage is their insolubility in common solvents due to strong intermolecular - interactions. The solubility of phthalocyanines can be increased by various methods such as the formation of anionic and cationic species and both axial and peripheral substitution. Substitution at the nonperipheral and peripheral positions of the benzo moieties usually enhances their solubility in organic solvents. The most important advantage of phthalocyanines compared to porphyrins is that their Q bands lie at longer wavelengths and are considerably more intense. In this book, you will find synthesis and some applications of various phthalocyanine derivatives.

Book Description
The purpose of this monograph is to provide a summary for those who are active in the field of phthalocyanine research. This volume allows the reader to quickly-and at a reasonable cost-determine what is being accomplished so that he may plan his own research programs. It covers such topics as synthesis, reactions, inks, energy systems, coatings, toners, and electrophotographic plates and developers, just to name a few. Packed with over 40 structural drawings of phthalocyanine molecules, this one-of-a-kind reference provides the necessary description and visualization to stimulate further research. This work is an indispensable resource for researchers and practitioners, both novice and experienced, in the field of phthalocyanine science and technology.

Book Description
Oxygen represents only 20% of the Earth's atmosphere, yet it is vital for the survival of aerobic organisms. There is a dark part of the use of oxygen that consists in generating reactive species that are potentially harmful to living organisms. Moreover, reactive oxygen species can combine with nitrogen derivatives and generate many other reactive species. Thus, living organisms are continuously assaulted by reactive species from external or internal sources. However, the real danger comes in the case of high concentrations and prolonged exposure to these species. This book presents an image of the mechanisms of action of reactive species and emphasizes their involvement in diseases. Inflammation and cancer are examined to determine when and how reactive species turn the evolution of a benign process to a malignant one. Some answers may come from recent studies indicating that reactive species are responsible for epigenetic changes.

Book Description
The definitive reference for phthalocyanine compound research and application By themselves as macrocyclics, phthalocyanines are of limited use; however, their metal complexes are critical to numerous industries as dyes, pigments, and industrial catalysts. Phthalocyanines is a complete, comprehensive reference toward the properties and applications of these compounds, presented as a four-volume set. Covering all aspects of synthesis, bonding, behaviors, characteristics, spectroscopy, hazards, reactions, and much more, this set provides chemists, biochemists, and molecular biologists with the information they need to work effectively with this large family of compounds.
