Book excerpt: The comprehensive resource for understanding the structure, properties, and applications of cyclodextrins Cyclodextrins: Properties and Industrial Applications is a comprehensive resource that includes information on cyclodextrins (CDs) structure, their properties, formation of inclusion complex with various compounds as well as their applications. The authors Sahar Amiri and Sanam Amiri, noted experts in the field of cyclodextrins, cover both the basic and applied science in chemistry, biology, and physics of CDs and offers scientists and engineers an understand of cyclodextrins. Cyclodextrins are a family of cyclic oligosaccharides consisting of (α-1,4)-linked α-D-glucopyranose units. The formation of inclusion complex between CDs as host and guest molecules is based on non-covalent interaction such as hydrogen bonding or van der waals interactions and lead to the formation of supramolecular structures. These supramolecular structures can be used as macroinitiator for initiating various type of reactions. CDs are widely used in many industrial products such as pharmacy, food and flavours, chemistry, chromatography, catalysis, biotechnology, agriculture, cosmetics, hygiene, medicine, textiles, drug delivery, packing, separation processes, environment protection, fermentation, and catalysis. This important resource: Offers a basic understanding of cyclodextrins for researchers and engineers Includes information of the basic structure of cyclodextrins and their properties Reviews how cyclodextrins can be applied in a variety of fields including medicine, chemistry, textiles, packing, and many others Shows how encapsulate corrosion inhibitors became active in corrosive electrolytes to ensure delivery of the inhibitors to corrosion sites and long-term corrosion protection Cyclodextrins offers research scientists and engineers a wealth of information about CDs with particular focus on how cyclodextrins are applied in various ways including in drug delivery, the food industry, and many other areas.

This book was released on 2021-07-29 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry is a subject that makes human life better. In the past few hundred years, the development of modern chemistry has also explained this meaning perfectly. Naturally, supramolecular chemistry also needs to move from theory to application, from laboratory to society, and ultimately benefit mankind. Insoluble drugs refer to poorly water-soluble drugs, which will lead to difficult absorption and transportation in vivo and low bioavailability. About 40% of the newly discovered natural active substances and nearly 60% of the chemically synthesized drugs are insoluble drugs. Their solubility (in water) is poor and it is difficult to achieve satisfactory clinical efficacy, so they have not been successfully developed into new drugs. Natural β-cyclodextrin can form supramolecular inclusion complexes with insoluble drugs, thus increasing the solubility of insoluble drugs. As a new drug delivery carrier, it has been widely studied and applied. Sulfobutyl eth-er-β-cyclodextrin is a derivative of β-cyclodextrin. Because of its good water solubility and biocompatibility, sulfobutyl ether-β-cyclodextrin can sig-nificantly increase the solubility, bioavailability and low nephrotoxicity of drugs. As a new type of injection drug delivery carrier, it has become one of the hot spots in the research and development of new drugs at home and abroad.

Download or read book Novel Macromolecular Architectures via a Combination of Cyclodextrin Host Guest Complexation and RAFT Polymerization written by Bernhard V. K. J. Schmidt and published by Springer Science & Business. This book was released on 2014-04-21 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, Bernhard Schmidt describes his research into two fields in the chemical sciences: supramolecular and macromolecular chemistry. Schmidt first investigates cyclodextrins (CDs), which are well known for the formation of supramolecular host/guest complexes with hydrophobic molecules in aqueous solution. Schmidt then also examines reversible addition-fragmentation chain transfer (RAFT) polymerization as a well-suited toll for the synthesis of water-soluble end-functionalized polymers. The author skillfully combines both concepts as a powerful tool to access reversibly forming macromolecular architectures. The novel methods and architectures presented in this work are highly interesting from both a fundamental point of view as well as a basis for the design of efficient drug release systems. The work in this thesis has led to a number of publications in top peer-reviewed journals.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Block copolymers consist of two or more incompatible polymer chains linked by covalent bonds. These block copolymer can separate into nanometer sized domains whose morphology depends upon the size of the block and interactions between them. The properties of block copolymers can be modified and potentially improved by introducing noncovalent interactions to replace covalent linkages between blocks to form supramolecular block copolymers. These kinds of materials combine the microphase separation inherent to block copolymers with the facile synthesis of supramolecular materials thereby affording new and unique materials. This dissertation focuses on synthesis and characterization of PS-b-PMA block copolymers with ion-pair junctions.Firstly, the chain-end sulfonated polystyrene ([omega]-sulfonated PS) was synthesized by reversible addition fragmentation chain transfer (RAFT) polymerization and postpolymerization modification. In the postpolymerization modification two methods were investigated: in the first one, the polymer was converted to a thiol-terminated polymer by aminolysis. Then a sulfonic acid end-group was produced then by oxidation of the thiol end-group with m-chloroperoxybenzoicacid (m-CPBA); in the second method, the RAFT-polymerized polymer was directly sulfonated by oxidation with m-CPBA. After purification by column chromatography, [omega]-sulfonated PS was obtained by both methods with greater than 95% end-group functionality as measured by titration. The sulfonic acid end-group could be neutralized with various ammonium or imidazolium counter ions through acid-base or ionic metathesis reactions. These polymers with ionic end-group can be used as model supramolecular building blocks.Secondly, ammonium end functionalized polymethylacrylate (PMA) was synthesized directly by RAFT polymerization using functional RAFT agent. Then chain-end sulfonated polystyrene and ammonium end functionalized polymethylacrylate (PMA) were used to synthesize A-B block copolymers by two different methods: the first method was by mixing two oppositely charged end group functionalized polymers; the second method was to ionically bond a RAFT agent to the chain end of an end sulfonated polymer to generate a supramolecular macro RAFT agent then an A-B block copolymer was prepared by RAFT polymerization using supramolecular macro-RAFT agent. The polymerization kinetics were investigated and the molecular weight and the chemical structure of the block copolymers were characterized by 1H-NMR and SEC. The results show that the ion-bonded supramolecular block copolymer, PS-PMA, have been successfully prepared with controlled molecular weight and narrow distribution.Thirdly, the morphology of the ion-bonded supramolecular PS-PMA diblock copolymers were investigated by small-angle X-ray scattering (SAXS) and rheological techniques. Several covalently bonded PS-PMA block copolymers were synthesized by RAFT polymerization and their micro domain structures and rheology behaviors were also investigated. The results showed that the electrostatic interactions between the end ion groups are able to overcome the thermodynamic repulsion of two blocks result in the formation of diblock copolymers with similar behaviors and morphology of traditional covalent bonded diblock copolymers and their micro domain structures remain to high temperatures.
