Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials synthesis is a field at the intersections of chemistry and physics with wide-ranging applications. There is a rich diversity of techniques to develop novel materials, but very little fundamental understanding of the mechanisms that drive the formation of solids, leading to an inability to predict a synthesis for a material with targeted properties. Solvothermal synthesis has garnered much attention in the field due to its relative predictability by combining solution-phase dynamics with reactive inorganic precursors. By incorporating composition-guided organic chemistry, which often benefits from predictable properties, metal-organic frameworks (MOFs) synthesized solvothermally have emerged among the most rationally designed solids in modern science. MOFs are a class of crystalline materials composed of metal-centers linked by organic ligands, forming large, porous networks. Structures, thus some properties, can be predicted given motifs for previously determined metal-center geometries and ligand-bonding environs. Further, targeted properties can be chemically tuned via optimization of the ligand and/or metal. Early efforts in the field resulted in the intriguing materials that failed to be commercially viable due to stability issue. Metal-organic frameworks using lanthanide metal-centers (Ln-MOFs) are thought to increase thermodynamic stability of the material and present unique electronic properties such as photoluminescence. The projects presented herein focus on investigating the properties and stability of lanthanide metal-organic frameworks with a naphthalene-based ligand. To be a commercially viable material, among other things a MOF must be stable in addition to having practical properties. The increased complexity in both the accessible geometries and electronic properties of lanthanides relative to light transition metals makes this work largely exploratory. Novel, isostructural cerium, neodymium, and europium Ln-MOFs comprised of two-dimensional sheets of metal-carboxylate centers bridged by naphthalene were synthesized and photoluminescence properties analyzed. The series of Ln-MOFs studied show they have robust photoactivity that may be exploited in small molecule or ion sensing. Compound [Ce(NO3)(NDC)][sub n] was found to be stable under basic and acidic aqueous conditions, but not thermally stable to 400°C. Small aromatic molecules were screened against [Nd(NO3)(NDC)][sub n] and fluorescence quenching shown to be correlated to spectral overlap, with significant signal quenching of benzene, but no observed selective change in excitation or emission wavelengths. Further, the compound was found to be stable to 300°C in open air. In particular, compound [Eu(NO3)(NDC)][sub n] was shown to be highly fluorescent in water and is readily quenched by trace concentrations of hazardous industrial by-product chromic acid. These investigations represent a broad effort to characterize Ln-MOFs in hopes of guiding the development of similar materials that exhibit robust chemical and thermal stability and relevant properties. Isoreticular synthesis is generally, but not exactly, an appropriate tool for replicating the synthesis with naphthalene-based ligands but different lanthanide metals. Procedurally altering the reported successful synthetic conditions with lanthanide metals is highly likely to produce isostructural and comparably stable compounds that exhibit unique electronic properties. Solvothermal synthesis using thiourea as a reactive solvent was also shown to produce unique lanthanide-metalloid complex germanium (II) sulfide doped lanthanum (III) hydroxide. The complex was found to photocatalytically degrade dye methylene blue in water under UV irradiation. While, not as efficient as known photocatalyst anatase titania, it represents a new class of lanthanum oxides doped with small band gap semiconductors that may be more easily optimized for photocatalytic processes than investigations on titanium dioxide have proven to be. Such intercalated lanthanum oxides may even have other relevant photo-driven applications, such as light harvesting or water-splitting.

Available in PDF, EPUB and Kindle. Book excerpt: Owing to the extensive interest in construction of functional metal organic frameworks (FMOFs), this book discusses the roles of functional groups on the structure and application of metal organic frameworks (MOFs). The contents of the book are classified based on the structural and chemical properties of organic functions, in order to make readers able to compare the different effects of each function on the structure and application of the MOFs. In each chapter, the chemical properties of applied functional groups are gathered to give deeper insight into the roles of organic functions in the structure and application of MOFs. In the function-application properties, the authors discuss how a functional group can dominate the host-guest chemistry of the MOFs and how this host-guest chemistry can expand the effectiveness and efficiency of the material in different fields of applications. Finally, function-structure properties are discussed. In function-application properties, it is discussed how a functional group can affect the topology, porosity, flexibility and stability of the framework. The features of this subject are novel and are presented for the first time.
