Available in PDF, EPUB and Kindle. Book excerpt: Anion recognition plays a critical role in a range of biological processes, and a variety of receptors and carriers can be found throughout the natural world. Chemists working in the area of supramolecular chemistry have created a range of anion receptors, drawing inspiration from nature as well as their own inventive processes. This book traces the origins of anion recognition chemistry as a unique sub-field in supramolecular chemistry while illustrating the basic approaches currently being used to effect receptor design. The combination of biological overview and summary of current synthetic approaches provides a coverage that is both comprehensive and comprehensible. First, the authors detail the key design motifs that have been used to generate synthetic receptors and which are likely to provide the basis for further developments. They also highlight briefly some of the features that are present in naturally occurring anion recognition and transport systems and summarise the applications of anion recognition chemistry. Providing as it does a detailed review for practitioners in the field and a concise introduction to the topic for newcomers, Anion Receptor Chemistry reflects the current state of the art. Fully referenced and illustrated in colour, it is a welcome addition to the literature.

Download or read book Chemosensors of Ion and Molecule Recognition written by J.P. Desvergne and published by Springer Science & Business Media. This book was released on 1997-04-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and use of chemosensors for ion and molecule recognition - a branch of supramolecular chemistry - have developed at an extraordinary rate. This imaginative and creative area involves work at the interface of organic and inorganic chemistry, physical chemistry, biology, medicine and environmental science and is providing new sensors based on the specific signal delivered by the analyte-probe reaction. The emergence of efficient fluorescent receptors has allowed the detection, identification, and even titration of, for example, heavy metal or radionuclide pollutants. Further, with sensors displaying specific and strong complexation properties, such materials could be detected and removed at very low concentrations. Further, among other species of biological interest, sugars, oxygen and carbon dioxide can actually be probed with optodes and similar devices. This is clearly just the beginning of a very promising line of research. Audience: Organic chemists interested in creating new chemosensors, as well as the many potential end users of such sensors.

Download or read book Supramolecular Chemistry of Selective Anion Recognition for Anions of Environmental Relevance written by Kristin Bowman-James and published by . This book was released on 2003 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original funded project (1996) had as its major goal the design and synthesis of polyammonium macrocyclic receptors for oxoanions of environmental importance, particularly those found in high level waste tanks. Nitrate was a major ion of focus. The project evolved over the last six years to target important and timely problems of critical interest to the EMSP mission. Emphasis was shifted from polyammonium receptors to lipophilic amide-based receptors more amenable for both separations and sensing applications in the last renewal, and significant effort was directed toward selective recognition of sulfate because of its detrimental role in the vitrification process. The last three years have been focused on the basic chemical aspects of anion receptor design of functional pH independent systems, with the ultimate goal of targeting the selective binding of sulfate, as well as design of separations strategies for selective and efficient removal of targeted anions. Key findings during these years include: (1) among the first synthetic sulfate-selective anion-binding agents; (2) simple, structure-based methods for modifying the intrinsic anion selectivity of a given class of anion receptors; and (3) two new classes of macrocyclic ligands, mixed amide/quaternary amine, thioamide-based macrocycles and cryptands.

Download or read book The Supramolecular Chemistry of Selective Anion Recognition for Anions of Environmental Relevance written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Work at carried out at ORNL since the inception of the project has served to demonstrate that the calix[4]pyrroles from the co-P.I.'s laboratory at the Univ. of Texas strongly enhance the extraction of sulfate by tricaprylmethylammonium nitrate or chloride in the presence of excess nitrate and chloride. Similar results were found in the case of the tetraamide macrocycles synthesized in the Bowman-James laboratory (Univ. of Kansas). Effort at the Univ. of Texas thus focused on generating new pyrrole-amide macrocycles that might combine the most favorable aspects of the calixpyrroles and the tetraamides. This culminated in the synthesis of several new receptors, which provided a ''matched set'' from whence insights into anion recognition could be inferred. As can be inferred from the data summarized in Table 1, small adjustments in the structure allow for a fine-tuning of the anion binding properties in favor of sulfate recognition, or in the case of injudicious modifications, selectivities that favor completely different classes of anionic substrates.

This book was released on 2004-06-17 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book documents the proceedings of the symposium "Fundamentals and Applications of Anion Separations" held during American Chemical Society National Meeting in Chicago, Illinois, August 25-30, 200I. Nearly 40 papers devoted to discussions on anion separation related to fundamental research and applications were presented. The symposium, sponsored by Osram Sylvania, BetzDearbom, and the Separation Science & Technology Subdivision of the Industrial & Engineering Chemistry Division of the American Chemical Society was organized by Bruce A. Moyer, Chemical Sciences Division, Oak Ridge National Laboratory, P.O. Box 2008, Building. 4500S, Oak Ridge, TN 37831-6119, and Raj P. Singh, Chemicals and Powders R&D, Osram Sylvania, Chemical and Metallurgical Products Division, Towanda, PA 18848. It drew presenters from Australia, the Czech Republic, France, Germany, Japan, South Africa, Thailand, the United Kingdom, and the United States. Separations constitute an integral part of chemical industry. Chemical products typically originate in resources that must be concentrated and purified, chemically transformed, and subjected to fmal purification. Effluent streams from the processes must be treated to recycle reusable components and to remove environmentally harmful species. Some industrial processes are devoted to environmental cleanup after pollution has occurred. In addition, many analytical methods require a separation for preconcentration, or a separation may be an inherent part of the analysis itself. Micro separations occurring at membranes or interfaces are also related phenomena employed for ion sensing. Many species targeted for separation are naturally anionic. Although the standard separations techniques ofextraction, ion exchange, adsorption, precipitation, etc.
