This book was released on 2012-07 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the important facts about the synthesis and biological studies of macrocyclic transition metal complexes. A detailed synthetic discussion of the reaction steps in each mechanism and their relationship with transition metal complexes has been considered. Macrocyclic ligands and their transition metal complexes depends upon the nature of reactants and the corresponding metal ion. The macrocyclic ligand are a growing class of compounds with varying chemistry a wide range of different molecular topologies and set of donor atoms. Aza type ligands appear as very promising to be used as antifertile, antibacterial, antifungal and other biological properties. Macrocyclic metal complexes play a central role in the construction of molecular materials, which display magnetic properties and find applications in material and supramolecular chemistry and biochemistry. It is believed that the present book will provide a succinct and clear introduction to synthesis, characterization and biological studies macrocyclic ligands with transition metal complexes that meets the needs of researchers at a variety of levels in several disciplines.

This book was released on 1993 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: As metal ion play an important role in biological systems, many complexes with synthetic macrocyclic ligands have been prepared to serve as models for biologically important species [1]. The presence of nickel in the enzyme hydrogenases is an example of the catalytic role of metal ions in redox reactions [2] of biological importance. The selectivity of cyclic antibiotics towards cation has commercial applications. Extending earlier work [4,5], we have synthesized new macrocyclic complexes of nickel (II) and cooper(II);the macrocycles were prepared by condensing 2, 6-diacetylpyridine with pyridine-2, 6-dicarboxylic acid dihydrazide.

Download or read book Transition Metals in Biochemistry written by A. S. Brill and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal ions in biological systems are of interest in biology, biochemistry, chemistry, medicine, and physics. Scien tists with rather different viewpoints, employing many methods, have contributed to this area. A concise review of the current state of the field will, to some extent, reflect the special knowledge of the person writing it - in this case application of physical methods to the investigation of metal coordination. x ray diffraction is one of the most important of these methods, but a useful treatment of X-ray structure analysis would be com parable in size with and beyond the scope of the monograph. Many results of X-ray diffraction studies are, of course, presented. Electron paramagnetic resonance spectroscopy has played a major part in the rapid advance in knowledge of the electronic struc tures of transition metal ions in biological systems. More gener ally, measurements involving light, microwaves, and magnetic fields are capable of producing much new information, and the required instrumentation is available at most research institu tions. Therefore light absorption and paramagnetic resonance are treated in depth. The principles described in the latter discus sions are broadly applicable, for example to the promising tech niques of X-ray spectroscopy (utilizing synchrotron radiation) and lanthanide-perturbed, very high-resolution nuclear magnetic resonance spectroscopy.
Download or read book Host Guest Complex Chemistry Macrocycles written by F. Vögtle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific and practical interest in coronands (crown ethers), cryptands, podands as complexing agents for cations as well as for anions and neutral low molecular species is undeniable 1,2). The chemistry of crown compounds is steadily increasing. About 250 original papers dealing with crown chemistry appeared only in 1980. New molecules· with crown ether properties are constantly synthesized and new applications discov,?red. Owing to lack of space, only a small number of the original publications is men tioned here. Thus, in the literature compilation only some, but relevant works are selected for each chapter. Whenever possible, reference is made to reviews or review-like articles alone by means of which origin,al works can be consulted. The reviews given under ref. 1) are considered to be the most relevant. The formulae presented in the figures should be understood as representative structures outlining a specific field. 2 Classification of Oligo-/Multidentate Neutral Ligands and of their Complexes Today, a distinction is made between the classical ring oligoethers (crown ethers) and monocyclic coronands, oligocyclic spherical cryptands and the acyclic podands with respect to topological aspects 3). This classification and the topology are illustrated in Fig. 1, each figure representing the minimum number of donor atoms and chain segments characteristic of each class of compounds. Multidentate mono cyclic ligands with any type of donor atoms are called coronands ("crown compounds"), while the term crown ether should be reserved for cyclic oligoethers exclusively containing oxygen as donor atom.
Download or read book Metallo Supramolecular Polymers written by Masayoshi Higuchi and published by Springer Nature. This book was released on 2019-11-12 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the synthesis, electrochemical and photochemical properties, and device applications of metallo-supramolecular polymers, new kinds of polymers synthesized by the complexation of metal ions and organic ditopic ligands. Their electrochemical and photochemical properties are also interesting and much different from conventional organic polymers. The properties come from the electronic intra-chain interaction between the metal ions and the ligands in the polymer chain. In this book, for example, the electrochromism that the Fe(II)-based metallo-supramolecular polymer exhibits is described: the blue color of the polymer film disappears by the electrochemical oxidation of Fe(II) ions to Fe(III) and the colorless film becomes blue again by the electrochemical reduction of Fe(III) to Fe(II). The electrochromism is explained by the disappearance/appearance of the metal-to-ligand charge transfer absorption. The electrochromic properties are applicable to display devices such as electronic paper and smart windows.
