Download or read book The Encapsulation Phenomenon written by Yan Voloshin and published by Springer. This book was released on 2016-04-27 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fundamental book presents the most comprehensive summary of the current state of the art in the chemistry of cage compounds. It introduces different ways of how ions and molecules can be encapsulated by three-dimensional caging ligands to form molecular and polymeric species: covalent, supramolecular, and coordination capsules. The authors introduce their classification, reactivity, and selected practical applications. Because encapsulation can isolate caged ions and molecules from external factors, the encapsulated species can exhibit unique physical and chemical properties. The resulting specific reactivity and selectivity can open up a range of applications, including chemical separation, recognition, chiral separation, catalysis, applications as sensors or probes, as molecular or supramolecular devices, or molecular carriers (cargo).A particularly strong emphasis in this book is on the summary and review of the synthesis of various types of cage compounds. Readers will find over 850 literature references summarized and clearly represented in over 600 schemes and illustrations. The book is structured by the types of caging ligands (covalent, supramolecular, or coordination capsules). The authors further arranged the chapters by ligand classes and types of encapsulated species (neutral molecules, anions, or cations). Readers will hence find an exhaustive reference resource and summary of the current state of research into encapsulated species, nowadays almost a separated realm of modern chemistry.

This book was released on 2012-12-06 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-ligand interactions are currently being studied in different fields, from a variety of points of view, and recent progress has been substantial. Whole new classes of compounds and reactions have been found; an arsenal of physical methods has been developed; mechanistic detail can be ascertained to an increasingly minute degree; and the theory is being developed to handle systems of ever-growing complexity. As usual, such multidisciplinarity leads to great opportunities, coupled with great problems of communication between specialists. It is in its promotion of interactions across these fields that Metal-Ligand Interactions: From Atoms, to Clusters, to Surfaces makes its timely contribution: the tools, both theoretical and experimental, are highly developed, and fundamental questions remain unanswered. The most fundamental of these concerns the nature of the microscopic interactions between metal atoms (clusters, surfaces) and ligands (atoms, molecules, absorbates, reagents, products) and the changes in these interactions during physical and chemical transformation. In Metal-Ligand Interactions, leading experts discuss the following, vital aspects: ab initio theory, semi-empirical theory, density functional theory, complexes and clusters, surfaces, and catalysis.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding and quantifying molecular interactions, which play a vital role in cellular mechanisms is essential in order to replicate nature and build complex molecular structures for the benefit of mankind. My research focuses on the synthesis and characterization of various organic and organometallic guest molecules to study the self-assembly and self-sorting properties with pumpkin-shaped Cucurbit[n]uril (CB[n], n = 7, 8) host macrocycles. CB's are cyclic glycoluril oligomers that self-assemble with typically positively charged and neutral guest molecules. First, we studied the self-sorting properties of octahedral Fe terpyridyl complexes substituted with neutral, positive and negatively charged amino acid side chains in presence of CB[8]. Second, we studied the arrangement of square planar Pt(II) acetylides upon interaction with CB[8]. We also studied the stimuli responsive properties of dynamic assemblies of Pt complexes and CB[8]. Finally, we investigated the self-sorting properties of quaternary assemblies of Pt complexes/CB[8.

Download or read book Octahedral Metal Clusters as Molecular Building Blocks of Coordination Polymers written by Lei Chen and published by . This book was released on 2011 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation work focuses on the use of cyanide-functionalized paramagnetic cluster [(Ta6Cl12[superscript i])(CN)12[superscript a]]3− with valence electron per cluster (VEC) = 15 as molecular building blocks of coordination polymers. Apical cyanide ligands are used as bridging ligands between the cluster and other molecular building blocks for the preparation of supramolecular assemblies with different dimensions. Using the self-assembly approach, eight new compounds were synthesized and their crystal structures have been determined from sing crystal X-ray diffraction. Two salts [La(DMF)(MeOH)[subscript 1.5](H2O)[subscript 0.5]Ta6Cl12(CN)6]·DMF (1) and Sm(H2O)2(DMF)Ta6Cl12(CN)6 (2) were synthesized using the anion [Ta6Cl12(CN)6]3− and solutions of La3+ and Sm3+. Both 1 and 2 precipitated quickly due to extremely low solubility of the products in the solvent system used, thus the products lacked crystallinity. The introduction of bridging ligand 4,4'-dipyridyl N,N'-dioxide (dpdo) enabled the formation of three extended frameworks [Eu(dpdo)(H2O)5(EtOH)2] [Ta6Cl12(CN)6]·dpdo·H2O· 4MeOH (3), [Eu(dpdo)3(H2O)4][Ta6Cl12(CN)6] ·5H2O (4) and [Eu(dpdo)2(H2O)3 Ta6Cl12(CN)6] ·2H2O ·0.75EtOH (5), by using the same starting materials but different stoichiometry and solvents. The compound [Zn2[Ta6Cl12(CN)6OH] · xH2O containing the Zn2 dimers was synthesized and structurally characterized, but it was difficult to prepare the compound quantitatively for further physical characterization. Two other novel compounds Zn3[Ta6Cl12(CN)4 X2]2 (7) and [Ni(en)2]2[Nb6Cl12(CN)6] · 2.5MeOH (8) were synthesized and their host-guest molecular interaction were studied. These results illustrate the approach of direct self-assembly is an effective way to prepare metal clusters based coordination polymers with novel structures and properties.
