Download or read book Phthalocyanines and Some Current Applications written by Yusuf Yilmaz and published by BoD – Books on Demand. This book was released on 2017-06-21 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Reactive Oxygen Species ROS in Living Cells written by Filip Cristiana and published by BoD – Books on Demand. This book was released on 2018-05-23 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Substituted Nickel Phthalocyanines Methods of Preparation written by Ali R A Shoukat and published by GRIN Verlag. This book was released on 2020-01-13 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2009 in the subject Chemistry - Materials Chemistry, , course: M.Phil, language: English, abstract: This thesis is about Substituted Nickel Phthalocyanines and their preparation. Currently intensive research work is going on in producing phthalocyanine compounds, which have been useful for applications, such as important industrial dyes and pigments since their early syntheses at the beginning of last century. They have been employed as charge carriers in photocopiers and laser printers, as well as materials for optical storage in recent years. Many potential applications were expected for these molecular materials which have a high thermal and chemical stability, for instance as potential industrial catalysts, solar cell functioning materials , gas sensors , nonlinear optical limiting devices , as power leads and as molecular switches in nanotechnology, photodynamic therapy agents, antiscrapie treatments, antimycotic materials, antimicrobial agents, as corrosion inhibitors, as photoconductors, electrical conductors, photosensitizers, photovoltaic materials and as colorants for cyano toners. Except for few derivatives, soluble phthalocyanine complexes were prepared for dyes and colors, which were found to be impure. Use of pure phthalocyanines and their derivatives are very important in order to exploit the full potential of the coloring effects, thermal stability, photoconductivity, semi conducting, catalytic and various other physico chemical properties. The solubility of phthalocyanines can be increased either by changing the number and nature of the substitutents or by changing the central metal ion. Ligation of the central metal ion will also enhance the solubility. In the present investigation, it was planned to synthesize various metal phthalocyanines containing different substitutents at particular positions, so that symmetrically tetra substituted derivatives will be prepared and their structural investigations will be carried out by using various physicochemical techniques. Hence it was found desirable to synthesize and characterize tetra anilido 2,9,16,23 substituted Ni Phthalocyanine in order to exploit the spectral, thermal stability and electrochemical characteristics and like other properties and hence the present study has been undertaken. This study may give greater insight on the properties of the unique character of Ni Phthalocyanine Derivatives and their potential applications.
