Macrocyclic and Supramolecular Chemistry

This book commemorates the 25th anniversary of the International Izatt-Christensen Award in Macrocyclic and Supramolecular Chemistry. The award, one of the most prestigious of small awards in chemistry, recognizes excellence in the developing field of macrocyclic and supramolecular chemistry Macrocyclic and Supramolecular Chemistry: How Izatt-Christensen Award Winners Shaped the Field features chapters written by the award recipients who provide unique perspectives on the spectacular growth in these expanding and vibrant fields of chemistry over the past half century, and on the role of these awardees in shaping this growth. During this time there has been an upsurge of interest in the design, synthesis and characterization of increasingly more complex macrocyclic ligands and in the application of this knowledge to understanding molecular recognition processes in host-guest chemistry in ways that were scarcely envisioned decades earlier. In October 2016, Professor Jean-Pierre Sauvage and Sir J. Fraser Stoddart (author for chapter 22 "Contractile and Extensile Molecular Systems: Towards Molecular Muscles" by Jean -Pierre Sauvage, Vincent Duplan, and Frédéric Niess and 20 "Serendipity" by Paul R. McGonigal and J. Fraser Stoddart respectively) were awarded the Nobel Prize in Chemistry alongside fellow Wiley author Bernard Feringa, for the design and synthesis of molecular machines.

Dr. Reed M. Izatt, Charles E. Maw Professor of Chemistry (Emeritus), Brigham Young University, U.S.A.
Reed M. Izatt received a BS degree in Chemistry from Utah State University (1951) and a PhD degree in Chemistry from Pennsylvania State University (1954). After post-doctoral work at Mellon Institute of Industrial Research, he embarked on an academic career at Brigham Young University retiring as Charles E. Maw Professor of Chemistry (1993). He is the author or co-author of over 550 publications.
Reed has edited several books, contributed numerous chapters in books, written many journal and review articles and presented plenary, invited, and regular lectures at universities worldwide; regional, national, and international chemistry conferences; and government laboratories.
Reed has been involved in research in macrocyclic chemistry since the late 1960s. Together with James Christensen, he organized the first Symposium on Macrocyclic Chemistry in Provo, Utah in 1977. This Symposium has thrived and was one of the major precursors of the present ISMSC.
