This book contains an overview of complex formation by macrocyclic ligand systems. The study of macrocyclic chemistry represents a major area of activity which impinges on a range of other areas in both chemistry and biochemistry. The field has characteristically yielded many interesting and unusual compounds. The text discusses the structures and properties of macrocyclic compounds; the synthesis of macrocycles; polyether crown and related systems; metal-ion and molecular recognition (host-guest chemistry); as well as kinetic, thermodynamic and electrochemical aspects of a range of macrocyclic systems. A discussion of the different categories of naturally occurring macrocycles is also included. Specialist and non-specialist alike will find this a useful text. Apart from serving as a convenient reference for established workers in the field, it should also prove useful to new graduate students as well as to researchers from other areas who seek a general introduction to the subject. The topics discussed also provide a suitable basis for a senior undergraduate or graduate course in macrocyclic chemistry and inorganic complexes.

Chemists have been aware of the existence of coordination compounds con taining organic macrocyclic ligands since the first part of this century ; however, only during the past few years have they expanded research into the chemistry of these compounds. The expansion was initiated in the early 1960s by the synthesis and characterization of compounds containing some new macrocyclic ligands. The synthesis of compounds which may serve as model systems for some natural products containing large rings as ligands provided the main goal for the early expansion of research effort; indeed, a recurrent theme behind much of the reported chemistry has been the analogy between synthetic macrocyclic compounds and many natural-product systems. More recently, the emphases of reported research have ranged over the whole spectrum of chemistry, and the number of publications that discuss macrocyclic chemistry has increased at a dramatic rate. The completed research has been reported in a variety of journals throughout the world but there has been no previous attempt to bring the major developments together under one cover. This book, therefore, attempts to satisfy the need for a single source in which there is both a collection and a correlation of information concerning the coordination chemistry of macrocyclic compounds. The chapters in this book discuss various aspects of macrocyclic chemistry, and while these chapters as a whole constitute an in-depth survey of the state-of the-art of the field, each chapter is written as a complete unit.

Macrocyclic ligands that can incorporate two or more metal ions giving homo- or hetero-dinuclear complexes are of considerable interest. Some of these hetero-dinuclear complexes are interesting as they mimic the active sites of metalloenzymes, such as cytochrome-c oxidase and bovine erythrocyte superoxide dismutase. Such systems are very helpful in investigating mutual influences of the two metal centers on electronic, magnetic, and electrochemical properties. Therefore, such types of system are very helpful in biological diagnostic applications. Research in inorganic chemistry has expanded in recent years by exploiting a variety of chelating ligands to modify and control the characteristics of metal ions in biological systems. Macrocyclic ligands offer the benefit of high stability complex formation and, through functionalization, the opportunity to modify the coordination environment. The pharmaceutical and bio-medical industry has yet to appreciate the impact coordination chemistry can have on the design of novel medicines. This may change the future as skilled multi-disciplinary experts may develop their investigation using a strategic approach to complex design.

This book covers the fundamental physical principles of the selective complexation, extraction, and transport of ions and molecules by macrocyclic compounds - both natural and synthetic. It also treats the use of these compounds for the extraction and transport of substrates in chemical and biological systems. Included are solution kinetic and thermodynamic properties of the complexes, along with relevant experimental methods, complemented by solution and solid-state structures. General and specific methods for the synthesis of macro(poly)cyclic specialised ligands are described. The book is useful as additional reading for undergraduate courses in chemistry (e.g. inorganic complexation chemistry, analytical chemistry, solution kinetics, synthesis) and biochemistry (ion transport/membrane phenomena); for graduate students in chemistry and biochemistry; for research workers in macrocyclic chemistry and biophysical chemistry; and for industrial laboratories involved in metal ion extraction and recovery.

The synthesis of macrocycles is an art in itself. Template-controlled synthesis provides elegant access to fascinating macrocyclic structures. Polyazamacrocycles, crown ethers, cryptands, rotaxanes, knots -- the range of macrocyclic compounds is as broad as their potential application as molecular switches, in ion exchange, electron transfer or catalysis. This book provides authoritative information on all aspects of template-controlled macrocyclizations. It covers in depth the current state of research on template processes - novel synthetic techniques and mechanistic approaches. The critical discussion of the diverse synthetic routes includes the detailed characterization of the broad variety of macrocyclic products. References to applications of macrocyclic compounds and over 1,500 citations make this handbook an indispensable tool for chemists in academia and industry. Researchers in organic and supramolecular chemistry, biotechnology, and inorganic chemistry will find inspiration for the design, synthesis, and myriad uses of new synthetic macrocycles.

Magnetic Resonance Imaging (MRI) is one of the most important tools in clinical diagnostics and biomedical research. The number of MRI scanners operating around the world is estimated to be approximately 20,000, and the development of contrast agents, currently used in about a third of the 50 million clinical MRI examinations performed every year, has largely contributed to this significant achievement. This completely revised and extended second edition: Includes new chapters on targeted, responsive, PARACEST and nanoparticle MRI contrast agents. Covers the basic chemistries, MR physics and the most important techniques used by chemists in the characterization of MRI agents from every angle from synthesis to safety considerations. Is written for all of those involved in the development and application of contrast agents in MRI. Presented in colour, it provides readers with true representation and easy interpretation of the images. A word from the Authors: Twelve years after the first edition published, we are convinced that the chemistry of MRI agents has a bright future. By assembling all important information on the design principles and functioning of magnetic resonance imaging probes, this book intends to be a useful tool for both experts and newcomers in the field. We hope that it helps inspire further work in order to create more efficient and specific imaging probes that will allow materializing the dream of seeing even deeper and better inside the living organisms. Reviews of the First Edition: "...attempts, for the first time, to review the whole spectrum of involved chemical disciplines in this technique..."—Journal of the American Chemical Society "...well balanced in its scope and attention to detail...a valuable addition to the library of MR scientists..."—NMR in Biomedicine
