Book Synopsis Hydrogen-bonded Capsules: Molecular Behavior In Small Spaces by : Julius Rebek, Jr
Download or read book Hydrogen-bonded Capsules: Molecular Behavior In Small Spaces written by Julius Rebek, Jr and published by World Scientific. This book was released on 2015-09-23 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes the behavior of molecules confined to small spaces. The small spaces are created by the self-assembly of modules into hollow capsular structures through hydrogen bonding; capsules assembled by metal/ligand binding or other forces are not included. Topics discussed include how assembly of capsules occurs, how molecules get in and out of the capsules, new spatial arrangements (stereochemistry) created in the capsules, and the altered shapes, interactions and reactivities of molecules held inside the small spaces. The descriptions emphasize molecular recognition phenomena and the perspective is that of physical organic chemistry.The book is the first monograph to treat reversible molecular encapsulation. More than 20 university and institute groups worldwide engage in this research, which represents the leading edge of activity in molecular recognition and the physical organic chemistry of confined molecules.

Available in PDF, EPUB and Kindle. Book excerpt: Supramolecular chemistry studies the phenomenon of self-assembly and emergent properties of monomers into larger structures and complexes, such as capsules. These supramolecular capsules are held together by non-covalent interactions such as hydrogen bonding and metal-ligand coordination, which are produced by the distinct moieties and functional groups of each individual molecular unit within the structure analogous to how the interactions of the various amino acid side chains govern the folding of a protein. One of the emergent and distinct properties of supramolecular complexes is the ability to encapsulate guest molecules. Furthermore, these capsules can form a kinetically-stable host-guest complex. The purpose of our research is to functionalize such kinetically-stable supramolecular structures with polymers for future applications in materials science. According to our hypothesis, polymer-appended metal-ligand and hydrogen-bonded capsules, such as the M 4L6 tetrahedron and the pyrogallol[4]arene hexamer, respectively, will be mechanically responsive and offer new properties in materials science. The first step in reaching that goal is to synthesize a polymer-appended M 4L6 tetrahedron and pyrogallol[4]arene hexamer and in doing so, we are currently developing novel synthetic routes to functionalize the capsules. The strategy we have taken for the polymer-appended M4L 6 synthesis involves a series of amide coupling reactions to make a ligand with a terminal alkyne in order to perform a copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction (also known as "click chemistry") with a polyethylene glycol azide polymer. Click chemistry and cross metathesis reactions are being explored to append an alkyne-functionalized polymer to an azide-monofunctionalized pyrogallol[4]arene hexamer. Further optimizations need to be made in the future to finalize the synthesis of the polymer-appended metal-ligand and hydrogen-bonded capsules.

Book Synopsis Guest Binding in Hydrogen-bonded Capsular Hosts by : Liam C. Palmer
Download or read book Guest Binding in Hydrogen-bonded Capsular Hosts written by Liam C. Palmer and published by . This book was released on 2005 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reversible hydrogen-bonded capsules self-assemble in organic solutions as hosts for molecular recognition. Guests for these capsules typically exchange by opening of one or more "flaps" on the host. The exchange process is slow on the NMR timescale and EXSY is used to measure rate constants. Resorcinarenes and pyrogallolarenes are shown to form large hexameric capsules in different solvents. The cavities of these structures can be filled with solvent or a wide array of additional guests. Cations make excellent guests for the resorcinarene hexamer, but do not enter the pyrogallolarene hexamer. The pyrogallolarene additionally assembles the hexameric capsule in non-polar organic solvents, including normal, branched, and cyclic hydrocarbons. A cylindrical, dimeric capsule forms to give a long narrow cavity that orients the guests inside. Coencapsulation of chiral acids leads to selection of diastereomeric pairs by NMR. Monte Carlo calculations help explain some of the observed selectivities.

Book Synopsis Encapsulation Nanotechnologies by : Vikas Mittal
Download or read book Encapsulation Nanotechnologies written by Vikas Mittal and published by John Wiley & Sons. This book was released on 2013-05-28 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique and comprehensive book covers all the recent physical, chemical, and mechanical advancements in encapsulation nanotechnologies. Encapsulation is prevalent in the evolutionary processes of nature, where nature protects the materials from the environment by engulfing them in a suitable shell. These natural processes are well known and have been adopted and applied in the pharmaceutical, food, agricultural, and cosmetics industries. In recent years, because of the increased understanding of the material properties and behaviors at nanoscale, research in the encapsulation field has also moved to the generation of nanocapsules, nanocontainers, and other nano devices. One such example is the generation of self-healing nanocontainers holding corrosion inhibitors that can be used in anti-corrosion coatings. The processes used to generate such capsules have also undergone significant developments. Various technologies based on chemical, physical, and physico-chemical synthesis methods have been developed and applied successfully to generate encapsulated materials. Because of the increasing potential and value of the new nanotechnologies and products being used in a large number of commercial processes, the need for compiling one comprehensive volume comprising the recent technological advancements is also correspondingly timely and significant. This volume not only introduces the subject of encapsulation and nanotechnologies to scientists new to the field, but also serves as a reference for experts already working in this area. Encapsulation Nanotechnologies details in part: The copper encapsulation of carbon nanotubes Various aspects of the application of fluid-bed technology for the coating and encapsulation processes The use of the electrospinning technique for encapsulation The concept of microencapsulation by interfacial polymerization Overviews of encapsulation technologies for organic thin-film transistors (OTFTs), polymer capsule technology, the use of supercritical fluids (such as carbon dioxide), iCVD process for large-scale applications in hybrid gas barriers Readership Encapsulation Nanotechnologiesis of prime interest to a wide range of materials scientists and engineers, both in industry and academia.
