Book Synopsis Modified Cyclodextrins: Scaffolds And Templates For Supramolecular Chemistry by : Chris J Easton

Download or read book Modified Cyclodextrins: Scaffolds And Templates For Supramolecular Chemistry written by Chris J Easton. This book was released on 1999-04-29. Available in PDF, EPUB and Kindle. Book excerpt: Through modification, the natural cyclodextrins are effective templates for the generation of a wide range of molecular hosts. This makes it possible to tailor a cyclodextrin host to a particular guest, to meet specific requirements in the host-guest complex, and opens the way to diverse new areas of supramolecular chemistry. Metallocyclodextrins, rotaxanes and catenanes, as well as surface monolayers of modified cyclodextrins, are readily obtained. The native cyclodextrins serve as scaffolds on which functional groups and other substituents can be assembled, with controlled geometry. This results in substantially improved molecular recognition and procedures for chemical separation, including enantiomer discrimination, through guest binding. Access to the gamut of functional groups greatly expands the utility of cyclodextrins in chemical synthesis and provides catalysts which mimic the entire range of enzymic activity. Modifications to the cyclodextrins also lead to a wide range of photochemistry of cyclodextrin complexes, through which the enhancement of guest reactivity occurs; in addition, light harvesting molecular devices and photochemical frequency switches may be constructed. In solution, modified cyclodextrins have been used to construct molecular reactors, as well as molecular, temperature and pH sensors. At surfaces, they form semipermeable membranes and sensor electrodes. Such exciting fields of chemistry, made possible only through modifications to the natural cyclodextrins, are the subject of this book.

Book Synopsis A Practical Guide to Supramolecular Chemistry by : Peter J. Cragg

Download or read book A Practical Guide to Supramolecular Chemistry written by Peter J. Cragg. This book was released on 2005-11-04. Available in PDF, EPUB and Kindle. Book excerpt: A Practical Guide to Supramolecular Chemistry is an introductory manual of practical experiments for chemists with little or no prior experience of supramolecular chemistry. Syntheses are clearly presented to facilitate the preparation of acyclic and macrocyclic compounds frequently encountered in supramolecular chemistry using straightforward experimental procedures. Many of the compounds can be used to illustrate classic supramolecular phenomena, for which clear directions are given, or may be developed further as part of the reader's own research. The book also describes techniques commonly used in the analysis of supramolecular behaviour, including computational methods, with many detailed examples. An invaluable reference for students and researchers in the field embarking on supramolecular chemistry projects and looking for a 'tried and tested' route into the chemistry of key compounds. An introductory guide to practical syntheses focusing on supramolecular chemistry. Fully referenced introductions explain the historical and contemporary importance of each compound Supplementary website including 3D molecular structures, FAQ's about syntheses and suggestions for further experiments

Book Synopsis Comprehensive Supramolecular Chemistry II by : George W. Gokel

Download or read book Comprehensive Supramolecular Chemistry II written by George W. Gokel. This book was released on 2017-06-22. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Supramolecular Chemistry II, Second Edition, Nine Volume Set is a ‘one-stop shop’ that covers supramolecular chemistry, a field that originated from the work of researchers in organic, inorganic and physical chemistry, with some biological influence. The original edition was structured to reflect, in part, the origin of the field. However, in the past two decades, the field has changed a great deal as reflected in this new work that covers the general principles of supramolecular chemistry and molecular recognition, experimental and computational methods in supramolecular chemistry, supramolecular receptors, dynamic supramolecular chemistry, supramolecular engineering, crystallographic (engineered) assemblies, sensors, imaging agents, devices and the latest in nanotechnology. Each section begins with an introduction by an expert in the field, who offers an initial perspective on the development of the field. Each article begins with outlining basic concepts before moving on to more advanced material. Contains content that begins with the basics before moving on to more complex concepts, making it suitable for advanced undergraduates as well as academic researchers Focuses on application of the theory in practice, with particular focus on areas that have gained increasing importance in the 21st century, including nanomedicine, nanotechnology and medicinal chemistry Fully rewritten to make a completely up-to-date reference work that covers all the major advances that have taken place since the First Edition published in 1996
