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.

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.

Despite the central role anionic species have been shown to play in both mineralogical and biological processes, until now there have been no comprehensive references dealing exclusively with anionic coordination chemistry. Written by a group comprising pioneering researchers from the United States and Europe, Supramolecular Chemistry of Anions covers all theoretical and practical aspects of anion complexation, from thermodynamics and structure to catalysis and various applications. The authors begin with the 1967 discovery of halide inclusion by bicyclic diammonium receptors and trace the development of anion coordination chemistry through the most recent developments in the field. Topics covered in detail include: * Pre-supramolecular anion chemistry * Natural and artificial molecules that can act as anion receptors * Preorganization and chemical design * Structural, thermodynamic, electrochemical, and photochemical aspects of anion coordination * Computer methods for receptor design and multiple host-guest relations * Anion receptor catalysis and molecular recognition and transformation of nucleotides Supramolecular Chemistry of Anions is a valuable professional resource for organic and inorganic chemists, analytical chemists, biotechnologists, pharmaceutical scientists, and environmental chemists. It also serves as an excellent graduate-level text for students of molecular recognition, catalysis, and biomimetic chemistry.

Building on the pioneering work in supramolecular chemistry from the last 20 years or so, this monograph addresses new and recent approaches to anion coordination chemistry. Synthesis of receptors, biological receptors and metallareceptors, the energetics of anion binding, molecular structures of anion complexes, sensing devices are presented and computational studies addressed to aid with the understanding of the different driving forces responsible for anion complexation. The reader is promised an actual picture of the state of the art for this exciting and constantly evolving field of supramolecular anion coordination chemistry. The topics range from ion channels to selective sensors, making it attractive to all researchers and PhD students with an interest in supramolecular chemistry.

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 project has as its focus the design and synthesis of polyammonium macrocyclic receptors for oxoanions of environmental importance. The basic research aspects of this project involve: (1) synthesis (and the search for improved synthetic methods); (2) solid state structure determination and thermodynamics studies (to ascertain structural criteria for and strength of anion binding); and (3) molecular dynamics simulations (to assess solution characteristics of the interactions between anions and their receptors). Applications-oriented goals include the fabrication of more selective anion-selective electrodes and the use of these compounds in liquid-liquid separations. The latter goal comprises the subcontract with Dr. Bruce Moyer at Oak Ridge National Laboratory. This report summarizes work after 1 year and 7 months of a 3-year project. To date, the authors have focussed on the design and synthesis of selective receptors for nitrate and phosphate.

The basic research aspects of this project involve synthesis (and the search for improved synthetic methods), solid state structure determination and thermodynamics studies (to ascertain structural criteria for and strength of anion binding), and molecular dynamics simulations (to assess solution characteristics of the interactions between anions and their receptors). Applications-oriented goals include the fabrication of more efficient anion-selective electrodes and the use of these compounds in liquid- liquid separations. The latter goal is the subcontract with Bruce Moyer at Oak Ridge National Laboratory. This first year the authors have focused on nitrates and phosphates. Considerable progress has been made in the basic areas of synthesis, solid state Structure, and molecular dynamics. Anion selective electrodes have also be made which show promising selectivities for oxoanions of interest. Below are described the major findings and significance in the categories of synthesis, structure and molecular dynamics, and electrode studies. Synthesis. The synthesis of polyaza macrocycles which are the focus of these studies is often tedious and time-consuming. A major breakthrough which the authors have made this year is to identify other polyaza macrocycles, which also bind the desired anions, but which are simpler to synthesize via a two step Schiff base/reduction process with high yields. This is truly significant since now the authors can obtain large quantities of the macrocycles and do multiple studies at once (crystallizations, thermodynamics, electrode, and eventually separations). Most of their studies to date have focused on monocyclic systems, but they are now beginning to examine bicyclic macrocycles, which can be synthesized by the same method starting with the tetraamine known as tren.
