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.
