Book excerpt: The book attempts to make available the recent developments in polyoxometalate (POM) synthesis. The focus centralizes on the functionalization of POMs with covalently organic moiety (for instance, the use of exogenous ligands such as carboxylate or bisphosphonate). It also delves into the development of lanthanide POMs, or the formation of blackberry-like assemblies. Likewise, the properties (redox properties, magnetism, etc...), and its applications (homogeneous and heterogeneous catalysis, photocatalysis, photoelectrocatalysis and photovoltaic cell development, etc.) are also analyzed.This application concerns also the catalysis of H2O oxidation, photodegradation of pollutants, and reduction of cationic metal to form original nanoparticles. The use of polyoxometalates as catalysts for biologically relevant reactions is also considered. One of the other aims of the book is to highlight some recent developments and perspectives in the domain of materials and their applications. For instance, the use of POM-organic photosensitizer hybrids can also be achieved for application in the generation of photocurrent and the development of new types of solar cells. By combining POMs with electrically active materials, a variety of applications have been explored and several examples of POM-based electronic materials are presented in this book.

Available in PDF, EPUB and Kindle. Book excerpt: The book highlights recent prominent results in the domain of the synthesis of new polyoxometalates with a specific attention to polyoxothioanions, and provides some novelties and perspectives in selected domains such as magnetism, luminescence and nanochemistry, and macroions self-assembly in solutions. The case of OC one-potOCO syntheses often used and reported in POMs synthesis is studied in terms of more complex solution speciation processes related to highly dynamical situation connected to factors such as pH, ionic strength, reaction time, temperature, counterion nature, concentration of starting materials, presence of electron donors and redox potentials. The behavior of macroions (2nm-6nm size range) in solution is shown to be quite different from the simple ionic solution or colloidal systems (DebyeOCoHuckel model). Their self-assembling into a single-layered, spherical, hollow vesicle structure, namely the OC blackberryOCO structure, is clearly described. Examples of spin clusters with tunable interactions are given and single molecule magnets based on POMs are specifically tackled. Besides paramagnetic transition metal centres and lanthanoid ions encapsulated in archetypal lacunary polyoxoanions, magnetically functionalized Kleperates are described, their discovery tracing back nearly 15 years.

Book excerpt: The book highlights recent prominent results in the domain of the synthesis of new polyoxometalates with a specific attention to polyoxothioanions, and provides some novelties and perspectives in selected domains such as magnetism, luminescence and nanochemistry, and macroions self-assembly in solutions. The case of “one-pot” syntheses often used and reported in POMs synthesis is studied in terms of more complex solution speciation processes related to highly dynamical situation connected to factors such as pH, ionic strength, reaction time, temperature, counterion nature, concentration of starting materials, presence of electron donors and redox potentials. The behavior of macroions (2nm-6nm size range) in solution is shown to be quite different from the simple ionic solution or colloidal systems (Debye–Huckel model). Their self-assembling into a single-layered, spherical, hollow vesicle structure, namely the “blackberry” structure, is clearly described. Examples of spin clusters with tunable interactions are given and single molecule magnets based on POMs are specifically tackled. Besides paramagnetic transition metal centres and lanthanoid ions encapsulated in archetypal lacunary polyoxoanions, magnetically functionalized Kleperates are described, their discovery tracing back nearly 15 years.

Download or read book Clusters Contemporary Insight in Structure and Bonding written by Stefanie Dehnen and published by Springer. This book was released on 2017-03-23 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume of Pharmacochemistry Library comprises the text of invited lectures presented at the 11th Noordwijkerhout-Camerino Symposium Trends in Drug Research, held in Noordwijkerhout, The Netherlands, from 11-15 May 1997. In the programme attention has been given to the generation of new biological target systems and the generation of new lead molecules, with presentations on e.g. combinatorial chemistry, compound libraries, database search, high throughput screening and molecular biology. Other topics discussed were the perspectives for new medicines for the gastro-intestinal tract, the major developments in the search for effective anti-HIV drugs and new aspects in synthetic approaches. In a special session three topics which currently draw much attention were discussed: How to deal with the major problem of resistance against antimirobial agents? Can the apoptosis mechanism be used as a drug target? Is the newly observed phenomenon of inverse agonism a general principle and has it consequences for drug development (and use?)

This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: MICHAEL T. POPE AND ACHIM MULLER Department of Chemistry, Georgetown University, Washington, DC 20057-2222, U.S.A.; Department of Chemistry, University of Bielefeld, D-4BOO Bielefeld 1, F.R.G. Polyoxometalates, from their discovery and early development in the final decades of the 19th century to their current significance in disciplines as diverse as chemistry, mathematics, and medicine, continue to display surprisingly novel structures, unexpected reactivities and applications, and to attract increasing attention worldwide. Most of the contributors to the present volume participated in the workshop held at the Center for Interdisciplinary Research at the University of Bielefeld, July 15-17, 1992. The choice of topics illustrates some of the variety of directions and fields in which polyoxometalates can play an important role. Although many of the leading polyoxometalate research groups are represented here, we regret that time constraints, financial limitations, and in some cases difficulties of communication did not allow us to include significant and imp- tant work from other groups outside Europe and North America. In the following we briefly review the current status of the field of po- oxometalates.

Download or read book Polyoxometalates written by Aaron P. Roberts and published by Nova Science Publishers. This book was released on 2016 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyoxometalates (abbreviated as POMs), also known as early-transition metal-oxygen anion clusters, is a large and rapidly growing series of inorganic compounds. POMs can be generally divided into two subclasses: isopolyoxometalates(IPOMs) and heteropolyoxometalates (HPOMs). The former refers to a class of isopoly compounds which contain the skeletal transition metal cations and oxide ions of the same metal element. In contrast, the latter one, known as heteropoly compounds (HPCs) as well, contains both heteroatom and coordination atoms. This book reviews properties of POMs, their structure and also their synthesis.
