Book Synopsis Polymers and Pyridazines by : Péter Tétényi
Download or read book Polymers and Pyridazines written by Péter Tétényi and published by CRC Press. This book was released on 2019-05-29 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years, a few articles have been published on the solid-phase synthesis of pyridazine derivatives. These methods apply to intermediates weakly bound to polymers, as a result of which the ester bond is cleaved easily, either during ring closure or right after it. There are few polymer-supported syntheses of heterocycles. This book, Polymers and Pyridazines, discusses a new strategy for polymer-supported synthesis of pyridazine derivatives with much higher reaction rates, applying higher loading and much wider reaction conditions due to the more stable attachment. On the basis of the research conducted, a fundamental break-through was achieved in solid-phase heterocyclic chemistry. The experiments are accompanied by colored drawings and 3D diagrams to help understand the importance of swelling and/or excess concentrations of reagents. Detailed experiments provide complete procedures with infrared difference spectra. The book will be a helpful reference for academy polymer specialists and postgraduate students studying polymer syntheses of general substrates.

Book Synopsis Cyclopentadienyl Pyridazines, Oxazines, and Thiophenes and Their Applications in Energy and Advanced Electronics by : Nathan Tice

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to their unique properties including environmental stability, high processibility, and low production cost, organic-based electronic materials are an attractive alternative to conventional inorganic semiconductors for use in advanced electronic applications. The growing interest and demand for renewable energy and next generation electronic devices has led to the incorporation of aromatic heterocycles into field-effect transistors (FETs), organic light-emitting diodes (OLEDs), and organic photovoltaic (OPV) cells. Specifically, thiophenes, furans, and pyridazines (6-membered aromatic rings containing two adjacent nitrogen atoms) represent alluring building blocks for electronic materials due to their ease of synthesis and stability. In addition, while oxazines (6-membered rings with an adjacent oxygen and nitrogen) have been utilized for their medicinal properties, they also possess interesting redox and optical properties. Polymers and discrete molecules/oligomers incorporating these heterocycles have shown promise in a number of commercial and industrial applications. Our current investigation focuses on the off-metal and transition metal chemistry of thiophenes, furans, pyridazines, and oxazines namely, the formation of fused-ring complexes bound u03b75 to a metal through a Cp moiety. By including a transition metal into fused-heterocycles, we hope to create hybrid materials which blend the synthetic versatility of organics with the novel structural and electronic properties that inorganic moieties possess. For example, formation of the desired complexes, [M(CO)3{u03b75-1,2-C5H3(1,4-(R)2N2C2}] (M = Mn, Re), was accomplished from a 1,2-diketo precursor, [M(CO)3{u03b75-1,2-C5H3(COR)2}] (R= 4-ClPh, 4-MeOPh, 5-BrTp). Reaction of these 1,2-diketo complexes with excess hydrazine under mild conditions (room temperature) afforded the desired pyridazine complexes in good yield (60-83%). These complexes display high solid state stability in air and relatively good stability in solution. Additionally, computational studies were performed on both these on- and off-metal heterocycles, including electrostatic potential mapping and natural bonding orbital modeling. Electrochemical polymerization of the free thienyl pyridazine ligand and corresponding organometallic complex via Cyclic Voltammetry (CV) was accomplished as well, affording redox stable thin films. CV studies were also performed on a number of the other on- and off-metal oxazines, pyridazines, and thiophenes.
Book Synopsis The Chemistry of Polymers by : Margaret Morris
Download or read book The Chemistry of Polymers written by Margaret Morris and published by . This book was released on 2020-09-22 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific field that is concerned with the chemical synthesis, structure, and the physical and chemical properties of polymers and macromolecules is known as polymer chemistry. Its principles and methods are also applicable in a variety of sub-disciplines of chemistry such as organic chemistry, physical chemistry and analytical chemistry. On the basis of their origin, polymers are subdivided into biopolymers and synthetic polymers. The functional and structural materials that make most of the organic matter in organisms are biopolymers. Synthetic polymers are the structural materials that are manifested in synthetic fibers, paints, building materials, furniture, plastics, mechanical parts and adhesives. This book is a compilation of chapters that discuss the most vital concepts in the field of polymer chemistry. Some of the diverse topics covered herein address the varied branches that fall under this category. Those in search of information to further their knowledge will be greatly assisted by this book.

Download or read book Advanced Energetic Materials written by National Research Council and published by National Academies Press. This book was released on 2004-01-30 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced energetic materialsâ€"explosive fill and propellantsâ€"are a critical technology for national security. While several new promising concepts and formulations have emerged in recent years, the Department of Defense is concerned about the nation's ability to maintain and improve the knowledge base in this area. To assist in addressing these concerns, two offices within DOD asked the NRC to investigate and assess the scope and health of the U.S. R&D efforts in energetic materials. This report provides that assessment. It presents several findings about the current R&D effort and recommendations aimed at improving U.S. capabilities in developing new energetic materials technology. This study reviewed U.S. research and development in advanced energetics being conducted by DoD, the DoE national laboratories, industries, and academia, from a list provided by the sponsors. It also: (a) reviewed papers and technology assessments of non-U.S. work in advanced energetics, assessed important parameters, such as validity, viability, and the likelihood that each of these materials can be produced in quantity; (b) identified barriers to scale-up and production, and suggested technical approaches for addressing potential problems; and (c) suggested specific opportunities, strategies, and priorities for government sponsorship of technologies and manufacturing process development.
