Book Description
Ce travail de thèse traite de l'auto-assemblage de composants de ligand et d'ions métalliques pour donner des complexes métallo-organiques. La construction de ces structures passe par la formation simultanée de deux types de liaisons: la liaison covalente imine (C=N) et la liaison de coordination métal-ligand (N->M). Contrairement à la synthèse organique classique qui repose sur des transformations irréversibles et qui a lieu sous contrôle cinétique, l'auto-assemblage moléculaire dirigé par l'effet "template" des ions métalliques se déroule sous contrôle thermodynamique et conduit le système vers la formation des produits les plus stables, souvent avec des rendements quantitatifs. Par conséquent, l'auto-assemblage moléculaire est non seulement un moyen rapide et efficace de construire des assemblages supramoléculaires complexes, irréalisables par chimie covalente classique, mais il permet aussi aux structures ainsi formées de se réarranger de façon dynamique via des réactions de substitution.

Book Description
Metallofoldamers are oligomers that fold into three-dimensional structures in a controlled manner upon coordination with metal ions. Molecules in this class have shown an impressive ability to form single-handed helical structures and other three-dimensional architectures. Several metallofoldamers have been applied as sensors due to their selective folding when binding to a specific metal ion, while others show promise for applications as responsive materials on the basis of their ability to fold and unfold upon changes in the oxidation state of the coordinated metal ion, and as novel catalysts. Metallofoldamers: From Helicates to Biomimetic Architectures describes the variety of interactions between oligomers and metal species, with a focus on non-natural synthetic molecules. Topics covered include: the major classes of foldamers and their folding driving force metalloproteins and metalloenzymes helicates: self-assembly, structure and applications abiotic metallo-DNA metallo-PNA and iDNA metallopeptides interactions of biomimetic oligomers with metal ions applications of metallofoldamers

Book Description
Advances in Structure and Activity Relationship of Coumarin Derivatives covers the structural behavior of various coumarin derivatives for various potential pharmaceutical applications. Based on substitution targeted for active sites, the book takes a rational approach for designing new and specific potent drugs, optimizing existing ones, and developing novel reactions. This focused primer describes the chemical structure and activity of coumarin derivatives to explore the effects of different substituents at specific positions, and their properties for effective bioactivity. Accessible and current coverage of coumarin derivatives from structure to potential applications Application of SAR technology to predict bioactivity of the derivatives based on its chemical structure Information for researchers in medicinal chemistry, pharmaceutical sciences, and related fields

Book Description
The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.
