Download or read book Crown Ethers and Analogous Compounds written by M. Hiraoka and published by Elsevier. This book was released on 2016-05-04 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of crown ethers by Pedersen in 1967, several thousands of crown ethers and analogous compounds have been synthesized. Their specific characteristics have been investigated and a variety of applications developed. These developments have led to new fields of chemistry called host-guest chemistry and supramolecular chemistry. This book presents the state-of-the-art of the chemistry of crown ethers and analogous compounds. The first chapter provides an orientation in the new fields of chemistry. Chapter 2 reviews advances in synthetic procedures for crown ethers and analogous compounds including azacrown ethers, thiacrown ethers, functionalized crown ethers, cryptands and others. The focus of chapter 3 is on the concept and synthetic strategies for the molecular design of new crown compounds. Chapters 4-7 are concerned with noteworthy topics in the applications of crown compounds. Chapter 4 deals with the application to ion-selective electrodes and liquid chromatography, both of which are the most important targets in the analytical application of crown compounds. One major application of crown ethers is the design and syntheses of artificial molecules which can catalyze a useful synthetic reaction in an enzyme-mimetic reaction manner, through novel non-covalent complexes. The strategies for enzymatic modelling with crown ethers are covered in chapter 5, while chapter 6 presents the principle of amine-selective colour complexation and its application. In chapter 7 switched-on crown ethers that can respond to environmental stimuli are reviewed. The final chapter is devoted to a wide-ranging discussion of developments in macrocyclic polyamine chemistry. Unlike crown ethers, macrocyclic polyamines, bearing nitrogen donor atoms which belong to a soft base, form complexes with ions of transition metals and heavy metals which are classified as soft acids. Therefore, macrocyclic polyamines are expected to have very versatile applications. Scientists in chemistry, biochemistry, physical organic chemistry, pharmaceutical chemistry and industrial chemistry will find this book a helpful summary and a stimulating contribution to research in this specialized field of crown compounds.

Download or read book Crown Ethers and Phase Transfer Catalysis in Polymer Science written by Lon Mathias and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase transfer catalysis or interfacial catalysis is a syn thetic technique involving transport of an organic or inorganic salt from a solid or aqueous phase into an organic liquid where reaction with an organic-soluble substrate takes place. Over the past 15 years there has been an enormous amount of effort invested in the development of this technique in organic synthe sis. Several books and numerous review articles have appeared summarizing applications in which low molecular weight catalysts are employed. These generally include either crown ethers or onium salts of various kinds. While the term phase transfer catalysis is relatively new, the concept of using a phasetrans fer agent (PTA) is much older~ Both Schnell and Morgan employed such catalysts in synthesis of polymeric species in the early 1950's. Present developments are really extensions of these early applications. It has only been within the last several years that the use of phase transfer processes have been employed in polymer synthesis and modification. Similarly, the use of polymer-bound phase transfer agents is also a recent development. These and related areas have nonetheless enjoyed explosive growth as mea sured by the number of publications and the variety of applica tions which have appeared. Several reviews dealing with these l 6 polymer-related investigations have been published.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the tremendous progress that has been made in the development of gas separation membranes based both on inorganic and polymeric materials. Materials discussed include polymer inclusion membranes (PIMs), metal organic frameworks (MOFs), carbon based materials, zeolites, as well as other materials, and mixed matrix membranes (MMMs) in which the above novel materials are incorporated. This broad survey of gas membranes covers material, theory, modeling, preparation, characterization (for example, by AFM, IR, XRD, ESR, Positron annihilation spectroscopy), tailoring of membranes, membrane module and system design, and applications. The book is concluded with some perspectives about the future direction of the field.

This book was released on 2002 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) A lengthy discussion of photovoltaic devices emphasizing I-V, C-V, and photoaction spectra interpretation is presented with relevant literature examples. Chapter 2. The synthesis of halo-functionalized crown ethers and efforts toward improving reaction yields for the macrocyclization are presented. Subsequent functionalization of the crown ethers with acetylide and thiophene groups via cross-coupling reactions, provides a wealth of receptors for the analyte paraquat. The affinities of the macrocycles for paraquat are determined through Stern-Volmer fluorescence quenching experiments. Correlations between structure and binding constants indicate that a-stacking interactions in two parallel planes, as seen for thiophene derivatized crown ether 33, affords the greatest complimentarity with paraquat, Ksv = 9665 +/- 179M-1. Acetylide functionalized crown ethers tend to have the weakest binding affinities, attributed to the poorer - extension. Increasing the electron-donating nature of the thiophene function as seen for 23 versus 15 leads to the doubling of the binding constant. Multiple crown ether receptor 29 does not display a non-linear Stern-Volmer plot, indicating that a single binding event occurs for this molecule. Relative to its monocrown analog 25, the binding constant for 29 is 1.2x larger, hinting at cooperativity between crown ether units. Chapter 3. Electrochemical studies on [2]-catenane 38, its non-catenated analog 23, and their respective polymers are undertaken in an effort to quantify the electronic disparity between the differing architectures ...

Book excerpt: Providing fundamental knowledge necessary to understand graphene’s atomic structure, band-structure, unique properties and an overview of groundbreaking current and emergent applications, this new handbook is essential reading for materials scientists, chemists and physicists.Since the 2010 physics Nobel Prize awarded to Geim and Novosolev for their groundbreaking work isolating graphene from bulk graphite, there has been a huge surge in interest in the area. This has led to a large number of news books on graphene. However, for such a vast inflow of new entrants, the current literature is surprisingly slight, focusing exclusively on current research or books on previous "hot topic" allotropes of carbon.This book covers fundamental groundwork of the structure, property, characterization methods and applications of graphene, along with providing the necessary knowledge of graphene’s atomic structure, how it relates to its band-structure and how this in turn leads to the amazing properties of graphene. And so it provides new graduate students and post-docs with a resource that equips them with the knowledge to undertake their research. Discusses graphene’s fundamental structure and properties, acting as a time-saving handbook for validated research Demonstrates 100+ high-quality graphical representations, providing the reader with clear images to convey complex situations Reviews characterization techniques relevant to grapheme, equipping the reader with experimental knowledge relevant for practical use rather than just theoretical understanding

This book was released on 2015-12-23 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crown ether is an early example of macrocyclic compound, crown ethers are generally composed of repeating ethylene components containing several ether groups. Crown ethers have the remarkable properties of recognizing and binding specific metal cations in complex mixtures. Schiff bases have played a significant role in the development of co-ordination chemistry as they readily form stable complexes with most transition metals. Therefore, this book highlighting on synthesis of crown ether Schiff bases, different types of crown ethers and its applications in various areas like, ion selective electrodes, catalyst, as a liquid crystals and metal complexation etc.
