Kristin Bowman-James received her Ph.D. in Chemistry at Temple University in Philadelphia, Pennsylvania, USA. She joined the Chemistry Department at the University of Kansas in 1975 and is currently University Distinguished Professor of Chemistry. Her research bridges<br> across the fields of supramolecular and transition metal coordination chemistry. She is an experienced author with over 100 papers, many reviews, has served as Editor for three books, and has received awards for both research and service.<br> <br> Antonio Bianchi received his Ph.D. in Chemistry at University of Florence in Italy in 1989. He was employed by the university first as a tenured Researcher, then as an Associate Professor, and from 2000 as Professor of General and Inorganic Chemistry. From 2006 to 2009 he<br> served as the Head of the Department of Chemistry of the said university. His diverse research interests encompass inorganic chemistry, supramolecular chemistry, coordination of anions, metallo-receptors and thermodynamics of coordination compounds. He has authored over<br> 200 papers and has served as editor of the book "The Supramolecular Chemistry of Anions" with his current co-editors.<br> <br> Enrique Garcia-Espa?a Monsonis received his Ph.D. in Chemistry at University of Valencia in Spain. After a period working in industry, he returned to the University of Valencia and held an assistant Professor position before becoming Professor at the Department of Inorganic<br> Chemistry in 2000. He has worked within Supramolecular Chemistry since 1984 and has authored or co-authored over 215 papers.

Building on the pioneering work in supramolecular chemistry from the last 20 years or so, this monograph addresses new and recent<br> 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<br> sensors, making it attractive to all researchers and PhD students with an interest in supramolecular chemistry.
