Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Developments in the field of stereochemistry began in the nineteenth century. The concept of chirality was first introduced by Jean Baptiste Biot. The present book deals with the major issue that is N-N chiral axis in 3-monoaminoquinazolin-4-(3H)-one, 3-diacylaminoquinazolinones and mono- and di-aniline (DAA and MAA) derivatives. The book presents the how to synthesize and characterize different MAA, DAA, MAQ, and DAQ compounds. Last chapter focus on the chemoselectivity especially competitive reactions of pyrrolidine and piperidine, diethylamine and diphenylamine, ethanolamine and diethanolamine, succinimide and phthalimide with DAQs and competitive reaction of pyrrolidine and piperidine with diacylaniline derivatives and acetyl chloride. The density functional and time dependent density functional theories have been applied and discussed the N-N bond as chiral axis, electronic, spectroscopic data. 120 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Organic molecules are the proficient materials which have been used in organic light emitting diodes (OLEDs). Developing new OLED materials with improved performance is the main goal of this book. One of the common electroluminescent and highly fluorescent complex is meridional isomer of tris(8-quinolinolato)aluminum (mer-Alq3) which is generally used in OLEDs. We have designed mono- and di-substituted derivatives with improved stability and mobility by substituting the EDGs and EWD groups at different position on the ligands. To design innovative and novel optical materials with high intrinsic mobility, new derivatives were designed and push-pull effect was investigated. We shed light on the geometric, electronic, photophysical and charge transfer properties of different designed materials. On the basis of electrostatic energy potential, we explained the stability of designed materials. We have explained the distribution of HOMO and LUMO on different individual ligands based on energy decomposition analysis. Blue, green, violet, yellow and red light emitters have been designed with improved stability, mobility and efficiency.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Organic molecules are the proficient materials which have been used in Organic field effect transistors and organic thin film transistors. Oligocenes studied for several decades currently provides among the best semiconductors in the field of organic electronics. The interest in the class of oligothiophene materials has also been intense ever since the first organic transistor. Metal phthalocyanines (MPcs) are planar or nearly planar organic molecules with a metal ion or a metal compound ion in the center. These molecules show interesting optical and electronic properties such as high photoconductivity and electroluminescence. This book deals with three major classes and presents the electronic, photophysical and charge transfer properties. Moreover, we also focused how to simulate the crystal structures. The last chapter deals with the packing effect on the intrinsic mobility. How stability can be improved has been discussed. Finally, this book deals with the major issues (a) simulation/prediction of the crystal structures (b) How to enhance the intrinsic mobility (c) How to improve the stability.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The dye-sensitized solar cells (DSSCs) are still in the early stages. This book would be helpful to educate the people towards alternative energy sources. Additionally, these energy sources would be pollution free as compared to coal which is a source of electricity. Until now, it's a severe challenge for both experiment and theory to make clear the fundamental properties of the ultrafast electron injection and come up to the satisfied efficiency of DSSC. Further developments in dye design will play a vital part in the continuing optimization of DSSC and it depends on the quantitative knowledge of dye sensitizer. So the theoretical investigations of the physical properties of dye sensitizers are very important in order to disclose the relationship among the performance, structures and the properties, it is also supportive to design and production of novel dye sensitizers with higher performance. Porpyrins are the stable organic chromophores which absorb visible light well and, luminesce with very high efficiency. The present book deals with the Structural, electronic and photophysical properties as well as structure-property relationship.OmniScriptum SRL, Str.
