Since 2000, when the Nobel Prize in Chemistry as awarded for conductive polymer research few studies have been performed concerning the conductive capabilities of discrete organometallic compounds. For this project, organometallic compounds were formed specifically with a transition metal included in the structure. Through oxidation and reduction reactions, the variation in the electrical conductivity could allow for an analysis of whether this unique structure would allow for tunability. The goal of this research was to begin with aromatic substituted fulvenes and perform various multistep synthesis processes, utilizing thallium salt intermediates, to produce several disubstituted cyclopentadienyl rhenium complexes. In this project, different rhenium complexes were synthesized accurately and with high yield utilizing methods that were straightforward and generated replicable results. Through melting range analysis, IR spectroscopy, 13C NMR, and 1H -NMR, the identity and purity of these compounds were confirmed.
With an enormous velocity, olefin polymerization has expanded to one of the most significant fields in polymers since the first industrial use about 50 years ago. In 2005, 100 million tons of polyolefins were produced - the biggest part was catalyzed by metallorganic compounds. The Hamburg Macromolecular Symposium 2005 with the title "Olefin Polymerization" involved topics such as new catalysts and cocatalysts, kinetics, mechanism and polymer reaction engineering, synthesis of special polymers, and characterization of polyolefins. The conference combined scientists from different disciplines to discuss latest research results of polymers and to offer each other the possibility of cooperation. This is reflected in this volume, which contains invited lectures and selected posters presented at the symposium.
Comprehensive Coordination Chemistry II (CCC II) is the sequel to what has become a classic in the field, Comprehensive Coordination Chemistry, published in 1987. CCC II builds on the first and surveys new developments authoritatively in over 200 newly comissioned chapters, with an emphasis on current trends in biology, materials science and other areas of contemporary scientific interest.
Organometallic Polymers focuses on the synthesis, characterization, and potential applications of organometallic polymers. The discussion is organized around seven themes: vinyl polymerization of organometallic monomers; condensation polymerization of organometallic monomers; polymer-bound catalysts; applications of organotin polymers; developments in organosilicon polymers; phosphonitrile and sulfur nitride polymers; and coordination polymers. This book is comprised of 33 chapters and begins with a general review of polymerized vinyl monomers containing transition metals, as well as the reactivity of such monomers in addition to homo- and copolymerizations. The following chapters explore the participation of the ferrocene nucleus in the polymerization of vinylferrocene and its effect on polymer properties; thermomechanical transitions of ferrocene-containing polymers; photocrosslinkable organometallic polyesters; and supported catalysts for ethylene polymerization. The remaining sections discuss antifouling applications of various tin-containing organometallic polymers; structure and applications of polyphosphazenes and polymeric sulfur nitride; and coordination of inorganic ions to polymers. This monograph will be a useful resource for organic chemists and research workers in the field.
Surface organometallic chemistry is a new field bringing together researchers from organometallic, inorganic, and surface chemistry and catalysis. Topics ranging from reaction mechanisms to catalyst preparation are considered from a molecular basis, according to which the "active site" on a catalyst surface has a supra-molecular character. This. the first book on the subject, is the outcome of a NATO Workshop held in Le Rouret. France, in May. 1986. It is our hope that the following chapters and the concluding summary of recommendations for research may help to provide a definition of surface organometallic chemistry. Besides catalysis. the central theme of the Workshop, four main topics are considered: 1) Reactions of organometallics with surfaces of metal oxides, metals. and zeolites; 2) Molecular models of surfaces, metal oxides, and metals; 3) Molecular approaches to the mechanisms of surface reactions; 4) Synthesis and modification of zeolites and related microporous solids. Most surface organometallic chemistry has been carried out on amorphous high-surf ace-area metal oxides such as silica. alumina. magnesia, and titania. The first chapter. contributed by KNOZINGER. gives a short summary of the structure and reactivity of metal oxide surfaces. Most of our understanding of these surfaces is based on acid base and redox chemistry; this chemistry has developed from X-ray and spectroscopic data, and much has been inferred from the structures and reactivities of adsorbed organic probe molecules. There are major opportunities for extending this understanding by use of well-defined (single crystal) oxide surfaces and organometallic probe molecules.
Joseph Chatt was a pioneering figure in coordination chemistry. Intended as a record of Chatt's life, work, and influence, this book begins with a description of Chatt's career presented by co-workers, contemporaries, and students, then goes on to show that many of today's leading practitioners in the field have been influenced by Chatt. The latest research in coordination chemistry is presented to highlight Chatt's continuing legacy, in sections on the synthesis and reactivity of hydrido and dihydrogen complexes, the chemistry of phosphines, transition metal complexes of olefins and related isolobal ligands, chemistry related to dinitrogen complexes, the biological work of the ARC unit of nitrogen fixation at the University of Sussex, and patterns and generalizations in stability and reactivity. Leigh is affiliated with the University of Sussex, UK, and Winterton is affiliated with the University of Liverpool, UK. The book is distributed in the US by Springer Verlag.

With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide insightful reviews of their areas of expertise, thus offering an overall picture of the state-- the art of the field. Nanostructured materials designate an increasing number of materials with designed shapes, surfaces, structures, pore systems, etc. Nanostructured materials with modified surfaces include those whose surfaces have been altered via such techniques as grafting and tethering of organic or organometallic species, or through various deposition procedures including electro, electroless and vapor deposition, or simple adsorption. These materials find important applications in catalysis, separation and environmental remediation. Materials with patterned surfaces, which are essential for the optoelectronics industry, constitute another important class of surface-modified nanostructured materials. Other materials are considered nanostructured because of their composition and internal organization.
There is a certain fascination associated with words. The manipulation of strings of symbols according to mutually accepted rules allows a language to express history as well as to formulate challenges for the future. But language changes as old words are used in a new context and new words are created to describe changing situations. How many words has the computer revolution alone added to languages? "Inorganometallic" is a word you probably have never encountered before. It is one created from old words to express a new presence. A strange sounding word, it is also a term fraught with internal contradiction caused by the accepted meanings of its constituent parts. "In organic" is the name of a discipline of chemistry while "metallic" refers to a set of elements constituting a subsection of that discipline. Why then this Carrollian approach to entitling a set of serious academic papers? Organic, the acknowledged doyenne of chemistry, is distinguished from her brother, inorganic, by the prefix "in," i. e. , he gets everything not organic. Organometallic refers to compounds with carbon-metal bonds. It is simple! Inorganometallic is everything else, i. e. , compounds with noncarbon-metal element bonds. But why a new term? Is not inorganic sufficient? By virtue of training, limited time, resources, co-workers, and so on, chemists tend to work on a specific element class, on a particular compound type, or in a particular phase. Thus, one finds element-oriented chemists (e. g.
The Progress in Inorganic Chemistry series provides inorganic chemistry with a forum for critical, authoritative evaluations of advances in every area of the discipline. Volume 52, Dithiolene Chemistry: Synthesis, Properties, and Applications continues this forum with a focus on dithiolene chemistry and a significant, up-to-date selection of papers by internationally recognized researchers. Dithiolene complexes have a remarkable set of properties, a fact which has made them the object of intense study for new materials and sensors.
