Available in PDF, EPUB and Kindle. Book excerpt: The work consists of two parts: In the first section the self aggregation of poly(ethylene oxide)-block-oligo-(p-benzamide) block copolymers was analyzed in detail. By varying the precipitation conditions for the block copolymer, different supramolecular structures were obtained. The dissolved polymer was drop wise added to chloroform, a selective solvent for poly(ethylene oxide). From hollow spheres with diameters in the micrometer regime to small rods with dimensions of several hundred nanometers in length and ten nanometers in width were observed.rnThe main part of the thesis deals with the synthesis and characterization of a novel conjugated oligomer: oligo(thiophene carboxamide)s. The needed monomer, a 2 aminothiophene 5 carboxylic acid, was made by the Gewald-Reaction, which is a multi-component, ring-closure reaction. This method generally allows the synthesis of tetra-substituted thiophenes, whereas the 3- and 4-position usually carries alkyl chains or esters. The so obtained material can be directly used in step-wise synthesis of well-defined oligomers, which exhibit interesting absorption and fluorescence phenomena. In dichloromethane, a bathochromic shift, depending on the oligomers length, was observed. The absorption energy of the pentamer is similar to that of the poly(thiphene carboxamide), revealing that the maximum effective conjugation length is achieved. In contrast to chloroform, aggregation of the oligomer, beginning with the trimer, was observed in N, N dimethylformamide. A charge transfer band was observed, which vanished with increased concentrations. A possible hypsochromic shift of that band, suggested the formation of H aggregates. Fluorescence spectroscopy as well as time-resolved fluorescence showed the expected trends for fully conjugated oligomers. Conjugation along the amide bond was also proven by quantum mechanical calculations.

This book was released on 2019-06-07 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides first-hand insights into advanced fabrication techniques for solution processable organic electronics materials and devices The field of printable organic electronics has emerged as a technology which plays a major role in materials science research and development. Printable organic electronics soon compete with, and for specific applications can even outpace, conventional semiconductor devices in terms of performance, cost, and versatility. Printing techniques allow for large-scale fabrication of organic electronic components and functional devices for use as wearable electronics, health-care sensors, Internet of Things, monitoring of environment pollution and many others, yet-to-be-conceived applications. The first part of Solution-Processable Components for Organic Electronic Devices covers the synthesis of: soluble conjugated polymers; solution-processable nanoparticles of inorganic semiconductors; high-k nanoparticles by means of controlled radical polymerization; advanced blending techniques yielding novel materials with extraordinary properties. The book also discusses photogeneration of charge carriers in nanostructured bulk heterojunctions and charge carrier transport in multicomponent materials such as composites and nanocomposites as well as photovoltaic devices modelling. The second part of the book is devoted to organic electronic devices, such as field effect transistors, light emitting diodes, photovoltaics, photodiodes and electronic memory devices which can be produced by solution-based methods, including printing and roll-to-roll manufacturing. The book provides in-depth knowledge for experienced researchers and for those entering the field. It comprises 12 chapters focused on: ? novel organic electronics components synthesis and solution-based processing techniques ? advanced analysis of mechanisms governing charge carrier generation and transport in organic semiconductors and devices ? fabrication techniques and characterization methods of organic electronic devices Providing coverage of the state of the art of organic electronics, Solution-Processable Components for Organic Electronic Devices is an excellent book for materials scientists, applied physicists, engineering scientists, and those working in the electronics industry.

Download or read book Handbook of Thiophene Based Materials written by Igor F. Perepichka and published by John Wiley & Sons. This book was released on 2009-07-17 with total page 910 pages. Available in PDF, EPUB and Kindle. Book excerpt: This essential resource consists of a series of critical reviews written by leading scientists, summarising the progress in the field of conjugated thiophene materials. It is an application-oriented book, giving a chemists’ point of view on the state-of-art and perspectives of the field. While presenting a comprehensive coverage of thiophene-based materials and related applications, the aim is to show how the rational molecular design of materials can bring a new breadth to known device applications or even aid the development of novel application concepts. The main topics covered include synthetic methodologies to thiophene-based materials (including the chemistry of thiophene, preparation of oligomers and polymerisation approaches) and the structure and physical properties of oligo- and polythiophenes (discussion of structural effects on electronic and optical properties). Part of the book is devoted to the optical and semiconducting properties of conjugated thiophene materials for electronics and photonics, and the role of thiophene-based materials in nanotechnology.
Download or read book Sulfur Chemistry written by Xuefeng Jiang and published by Springer Nature. This book was released on 2019-08-28 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Most syntheses in the chemical research laboratory fail and usually require several attempts before proceeding satisfactorily. Failed syntheses are not only discouraging and frustrating, but also cost a lot of time and money. Many failures may, however, be avoided by understanding the structure-reactivity relationship of organic compounds. This textbook highlights the competing processes and limitations of the most important reactions used in organic synthesis. By allowing chemists to quickly recognize potential problems this book will help to improve their efficiency and success-rate. A must for every graduate student but also for every chemist in industry and academia.
