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.

A number of examples are introduced in which the contribution of cation-π interactions was evidenced by X-ray structures, spectroscopies, computations, and other means. The latest developments in these areas are remarkable; therefore, many recent examples are included.As this book covers the basic aspects of the applications of cation–π interactions it is useful for students and researchers in a wide variety of scientific fields. In addition, the book will not only facilitate understanding of the phenomena occurring in various systems but also provides insights into the design of new catalysts, reactions, and materials.
Download or read book Host Guest Complex Chemistry Macrocycles written by F. Vögtle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific and practical interest in coronands (crown ethers), cryptands, podands as complexing agents for cations as well as for anions and neutral low molecular species is undeniable 1,2). The chemistry of crown compounds is steadily increasing. About 250 original papers dealing with crown chemistry appeared only in 1980. New molecules· with crown ether properties are constantly synthesized and new applications discov,?red. Owing to lack of space, only a small number of the original publications is men tioned here. Thus, in the literature compilation only some, but relevant works are selected for each chapter. Whenever possible, reference is made to reviews or review-like articles alone by means of which origin,al works can be consulted. The reviews given under ref. 1) are considered to be the most relevant. The formulae presented in the figures should be understood as representative structures outlining a specific field. 2 Classification of Oligo-/Multidentate Neutral Ligands and of their Complexes Today, a distinction is made between the classical ring oligoethers (crown ethers) and monocyclic coronands, oligocyclic spherical cryptands and the acyclic podands with respect to topological aspects 3). This classification and the topology are illustrated in Fig. 1, each figure representing the minimum number of donor atoms and chain segments characteristic of each class of compounds. Multidentate mono cyclic ligands with any type of donor atoms are called coronands ("crown compounds"), while the term crown ether should be reserved for cyclic oligoethers exclusively containing oxygen as donor atom.
Download or read book Metal Ligand Interactions written by N. Russo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 2002, a NATO-ASI was held in Cetraro (CS), Italy on the theme of "Metal-Ligand Interactions in Molecular-, Nano-, Micro-, and Macro-systems in Complex Environments". This event has followed the previous ones held in the same place in 1991, 1994 and 1998. In the present and the previous schools a broad interdisciplinary cross-section of experimental and theoretical researchers, interested in a better understanding of metal-ligand interactions from different viewpoints, was linked together to exchange experience, to review the state-of-the-art, to indicate new techniques and methods, to explore new fields and perspectives. Particular emphasis was given to the problems related with the crossing from molecular systems to nano-, macro-and micro-scale materials and to the effects of the environment on the properties of the molecular systems. The school was organized around lectures and special research seminares given by leading experts in the following fields: • metal clusters • inorganic complexes and materials • surface phenomena • adsorption and catalysis • organic and bio-inorganic systems • ab initio theory • density functional theory • classical and quantum dynamics This volume contains the formal lectures and selected contributed papers and describes the main aspects and problems tackled during the 12 days of the event.

Download or read book Mass Spectrometry of Non Covalent Complexes written by Christoph A. Schalley and published by John Wiley & Sons. This book was released on 2009-09-08 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Details the many benefits of applying mass spectrometry to supramolecular chemistry Except as a method for the most basic measurements, mass spectrometry (MS) has long been considered incompatible with supramolecular chemistry. Yet, with today's methods, the disconnect between these two fields is not warranted. Mass Spectrometry and Gas-Phase Chemistry of Non-Covalent Complexes provides a convincing look at how modern MS techniques offer supramolecular chemists a powerful investigatory toolset. Bringing the two fields together in an interdisciplinary manner, this reference details the many different topics associated with the study of non-covalent complexes in the gas phase. The text begins with brief introductions to supramolecular chemistry and such relevant mass spectrometric methods as ionization techniques, analyzers, and tandem MS experiments. The coverage continues with: How the analyte's transition into the gas phase changes covalent bonding How limitations and pitfalls in analytical methods may produce data misinterpretations Artificial supramolecular aggregates and their examination Biomolecules, their complexes, and their examination After the general remarks making up the first section of the book, the following sections describe specific experimental procedures and are illustrated with numerous examples and short tutorials. Detailed citations end each chapter. Mass spectrometrists, supramolecular chemists, students in these fields, and interested readers from other disciplines involving the study of non-covalent bonds will all value Mass Spectrometry and Gas-Phase Chemistry of Non-Covalent Complexes as an innovative and practical resource.

Download or read book Macrocyclic Polyether Syntheses written by G. W. Gokel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It seems likely that no project of this magnitude is undertaken in the absence of several motivations. This book is no exception. There are, from our perspective, at least two rational reasons for conducting this cataloging and organizational effort. The first of these is the obvious fact that a very large number of macrocyclic polyethers have now been prepared and nowhere is there a comprehensive listing of them. A number of excellent reviews have been published dealing with one or more aspects of macrocycle chemistry, but we felt a great need for a single source listing known compounds. We have, the- fore, attempted to provide such a listing to assist ourselves in keeping track as well as, we hope, helping others in this field. We also felt that there was a need for a survey of methods which have been utilized in the syntheses of these cation binders so that the novice could establish some starting point. Wherever possible, we have also attempted to point to the motivations which en gendered the various syntheses. The somewhat irrational reason which propelled us into this endeavor was the ques tioning of Charlie Morgan who often asked if one or another obscure compound had been synthesized. As often as not, we were uncertain arid now at least have a reference which, if not absolutely complete, will at least save face.
