Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Lesson Plan from the year 2019 in the subject Chemistry - Anorganic Chemistry, grade: A, , language: English, abstract: This laboratory material seeks to help fresh teachers of the UG-PG departments as well as self studying students. It eliminates the difficulties which are common in the starting stage of a teaching carrier regarding solution preparations in various concentrations, calculations and procedures for the experiments and the practical set up.Moreover, the work is helpful to understand the role of reagents/chemicals used in experiments, reactions, conditions and structures. The work will provide all the information related to the complexometric titrations.

Taschenbuch. Condizione: Neu. Neuware -The present book brief about history of phthalocyanine molecules, origin, structure and its similarity with the bio-molecule, various methods of preparation and its wide applications as colorizing materials, non colorants, semiconductors and as well as in medicinal field.We have discussed three types of substituents attached to phthalocyanine periphery symmetrically at 2, 9, 16, 23 positions. We have prepared 2, 9, 16, 23 tetra carboxy metal phthalocyanine as a starting material and treated various substituents as precursors at suitable experimental condition to get the desired products. The overall study of the present work summarizes that the different substituent metal Pc¿s can be synthesized by the reaction of tetracarboxy substituted metal Pc¿s with aromatic hydrazides,thiazoles and triazoles for good yields. 1. Tetracarboxy phthalocyanines were prepared by reacting phthalic anhydride in the presence of urea, metal salts and the catalyst with good yield and simple purification procedure.2. 2-(naphthalen-1-yloxy)acetohydrazide used as a precursor for the synthesis of oxadiazole substituted MPc. 3. And fictionalization of Pc macrocycle with oxadiazole is highly attractive.Books on Demand GmbH, Überseering 33, 22297 Hamburg 84 pp. Englisch.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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.
