Book excerpt: Transition metal nitride (N3-) complexes exhibit useful reactivity towards heteroatom transfer, as well as providing valuable insight into the mechanisms of dinitrogen reduction and ammonia oxidation. Salen ligands are capable of forming complexes with a large number of metal ions in different oxidation states and are thus a versatile platform in coordination chemistry research. By incorporating salen ligands with a variety of R-group substituents at the para position of the phenolate moieties, the electronic structure and thus the reactivity of the nitride ligand can be modified. This thesis will focus on the synthesis, characterization and reactivity of Cr nitride complexes bearing modified salen ligands (R = NO2, CF3, tBu, OMe, OiPr, NMe2, and NEt2). Salen ligands are well-known for their ability to form ligand radicals upon oxidation, as opposed to metal-based oxidation. Oxidation of CrNSalNMe2 and CrNSalNEt2 yields CrV ligand radical species, whereas the other less donating R-groups yield high-valent CrVI nitride complexes. Oxidized complexes were characterized by both experimental and theoretical techniques including UV-vis-NIR spectroscopy, electron paramagnetic resonance spectroscopy, electrochemistry, and density functional theory calculations. Depending on the locus of oxidation, desirable reactivity may be observed such as C-H bond activation. The addition of exogenous ligands may further activate the nitride ligand and facilitate homocoupling or C-H bond activation pathways.

This book was released on 2020 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal nitride complexes exhibit interesting structure and bonding properties that are invoked when discussing the reactivity of these systems. The nitride (N3-) moiety can be either nucleophilic or electrophilic based on a variety of factors such as metal identity, oxidation state, and nature of the ancillary ligands. Herein, the electronic tuning of Cr salen nitride complexes is investigated via modulation of phenolate para-R substituents of varying electron donating ability (R = CF3, tBu, NMe2) in order to influence reactivity. Salen ligands can exhibit non-innocent behavior, implying that redox processes can either be metal or ligand-based. This feature allows the ligand to help facilitate difficult substrate transformations uncommon to Earth-abundant first-row metals. Depending on the para-R group, the locus of oxidation in Cr nitride salen complexes (metal vs. ligand) can be influenced. The electronic structure of oxidized compounds is detailed, allowing for rationalization of nitride reactivity based on oxidation locus.

This book was released on 2020 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal complexes incorporating redox-active ligands have the potential to facilitate controlled multielectron chemistry, enabling their use in catalysis and energy storage applications. Moreover, the use of transition metal complexes containing redox-active ligands has been extended to two- (2D) and three-dimensional (3D) materials, such as supramolecular assemblies (i.e., metallacycles, molecular cages, or macrocycles) and metal-organic frameworks (MOFs) for catalytic, magnetic, electronic, and sensing applications. Salens (N2O2 bis(Schiff-base)-bis(phenolate) are an important class of redox-active ligands, and have been investigated in detail as they are able to stabilize both low and high metal oxidation states for the above-mentioned applications. The work in this thesis focuses on the synthesis and electronic structure elucidation of metal salen complexes in monomeric form, as discrete supramolecular assemblies and 3D MOFs. Structural and spectroscopic characterization of the neutral and oxidized species was completed using mass spectrometry, cyclic voltammetry, X-ray diffraction, NMR, UV-Vis-NIR, and EPR spectroscopies, as well as theoretical (DFT) calculations. Chapter 2 discusses the synthesis and electronic structure evaluation of a series of oxidized uranyl complexes, containing redox-active salen ligands with varying para-ring substituents (tBu, OMe, NMe2). Chapters 3 and 4 discuss the incorporation of a redox-active nickel salen complex equipped with pyridyl groups on the peripheral positions of the ligand framework into supramolecular structures via coordination-driven self-assembly. The self-assembly results in formation of a number of distinct metallacycles, affording di-, tetra-, and octa-ligand radical species. Finally, the design, synthesis, and incorporation of metal salen units into MOFs is discussed in Chapter 5. Preliminary assembly and oxidation experiments are presented as an opportunity to explore the redox-properties of salen complexes incorporated into a solid-state 3D framework. Overall, the work described in this thesis provides a pathway for salen ligand radical systems to be used in redox-controlled host-guest chemistry, catalysis, and sensing.

This book was released on 2018 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: In several oxidoreductase metalloenzymes, organic cofactors are transiently converted to radicals in order to achieve efficient catalytic turnover. This is, for example, the case of a tyrosine residue in galactose oxidase. Similarly, small-molecule catalysis can be improved when a transient radical ligand is involved. The present work aims at tailoring the structure of three classic ligands to make them redox-active, i.e. active participants in the electronic structure and reactivity of their complexes upon oxidation. The approach is to render an aromatic moiety on the ligand electron-rich by addition of NMe2 substituents. The first chapter describes a neutral Ni(II) complex with 1. This complex undergoes two reversible oxidations that were characterized by electrochemistry, electron paramagnetic resonance spectroscopy, optical spectroscopy and density functional theory. These oxidations are ligand-based, producing a radical ligand and a diiminoquinone successively. The second chapter investigates Cu(II) complexes of 1 and 2, for the bio-relevance of Cu in several oxidoreductases. Both ligands oxidize to a radical that is ferromagnetically coupled to the unpaired electron of Cu(II). Spectroscopic characterization and theoretical calculations provide a description of the electronic structure of the oxidized complexes. The third chapter looks at a Co(III) complex of 3, which is electron-rich and undergoes redox processes at low potentials. The optical absorption behaviour of the oxidized products is similar to that of the free ligand, suggesting ligand-based oxidation. As a whole, this thesis describes the effect of strongly electron-donating ligand substituents on the redox and electronic properties of a metal complex. The design leads to an easy strategy by which to tune the electronic structure of a complex by controlling the redox properties of its ligand.

Book excerpt: 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.

This book was released on 1998-06-17 with total page 881 pages. Available in PDF, EPUB and Kindle. Book excerpt: The school held at Villa Marigola, Lerici, Italy, in July 1997 was very much an educational experiment aimed not just at teaching a new generation of students the latest developments in computer simulation methods and theory, but also at bringing together researchers from the condensed matter computer simulation community, the biophysical chemistry community and the quantum dynamics community to confront the shared problem: the development of methods to treat the dynamics of quantum condensed phase systems.This volume collects the lectures delivered there. Due to the focus of the school, the contributions divide along natural lines into two broad groups: (1) the most sophisticated forms of the art of computer simulation, including biased phase space sampling schemes, methods which address the multiplicity of time scales in condensed phase problems, and static equilibrium methods for treating quantum systems; (2) the contributions on quantum dynamics, including methods for mixing quantum and classical dynamics in condensed phase simulations and methods capable of treating all degrees of freedom quantum-mechanically.

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