Book Synopsis Pathways to Functionalized Siloxanes from Polyhedral Oligomeric Silsesquioxanes by : Badru-Deen Barry
Download or read book Pathways to Functionalized Siloxanes from Polyhedral Oligomeric Silsesquioxanes written by Badru-Deen Barry and published by . This book was released on 2021 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is an account of my efforts toward developing strategies for the synthesis of novel functionalized polyhedral oligomeric silsesquioxanes (POSS). These organic/inorganic nanomaterials date back to 1946 and the pioneering work of Scott's synthesis of octamethylsilsesquioxane. POSS cages constitute a framework of silicon-oxygen polyhedron with reactive or inert organic coronae. These hybrid nanostructures are versatile precursors that find applications in polymer chemistry, catalysis, engineering, medicine, and electronics. Their properties are partly dictated by the peripheral organic groups. They are generally benign and easily processible into composite materials with high thermal degradation temperatures, low dielectric constants and superior mechanical properties. These features of POSS compounds have prompted growing interest in their exploration, particularly their use as models for the synthesis of the next generation hybrid nanocomposites. POSS molecules come in different cage sizes with condensed and incompletely condensed structures. The completely condensed analogues are denoted as Tn, where n = number of silicon atoms in the cage and n 9́Æ 6. Whereas the cubic/condensed silsesquioxanes were the initially discovered compounds, most explorations today are focused on the incompletely condensed di-, tri-, and tetra-functional scaffolds because of the ability to derivatize them into more functional materials for a myriad of applications. Even with the partially condensed structures, current research focus on this family of compounds has been dominated by the highly symmetric tetrafunctional octasilsesquioxane otherwise known as the double-decker oligomeric silsesquioxane. This functional POSS precursor has enormous potential for the synthesis of nanosized hybrid clusters with defined shape, structure, and physicochemical properties.In this study, efforts have been made to disclose strategies for the synthesis of asymmetrically functionalized double-decker shaped silsesquioxanes that can serve as nano-linkers to two dissimilar polymer matrices. The conversion of dead-end silsesquioxanes into more functional cage precursors, and surface transformation of cubic and functionalized DDSQs into modifiable precursors for the synthesis of well-defined 3D networks well among my aims. POSS cages used in these investigations were obtained either from commercially available cages or cage-like precursors or were synthesized from monomeric trialkoxy- (or trichloro-)silanes by hydrolytic condensation. Products obtained from this study could open an avenue for the exploration of new structure/property relationships and provide a unique way by which cages can be used as linkers to form both linear POSS/polymer and 3D networks. This research promises to open a new research direction for the synthesis of novel materials that combine three unconventional materials into hybrid POSS/polymer composites. With the asymmetric POSS cage as the building block, unprecedented properties may emerge from the synergy of these building blocks.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of polymer nanocomposites and hybrid materials with polyhedral oligomeric silsesquioxanes (POSS). Among inorganic nanoparticles, functionalized POSS are unique nano-building blocks that can be used to create a wide variety of hybrid and composite materials, where precise control of nanostructures and properties is required. This book describes the influence of incorporation of POSS moieties into (organic) polymer matrices on the mechanical, thermal and flammability behavior of composites and hybrid organic-inorganic materials. Importantly, POSS-containing materials can be bio-functionalized by linking e.g. peptides and growth factors through appropriate surface modification in order to enhance the haemo-compatibility of cardiovascular devices made of these materials. This volume includes descriptions of synthesis routes of POSS and POSS-containing polymeric materials (e.g. based on polyolefines, epoxy resins and polyurethanes), presentation of POSS’ role as flame retardants and as biocompatible linker, as well as the depiction of decomposition and ageing processes.
Book Synopsis Routes to Silsesquioxanes Functionalization by : Badru-Deen Barry
Download or read book Routes to Silsesquioxanes Functionalization written by Badru-Deen Barry and published by . This book was released on 2019 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyhedral oligomeric silsesquioxanes (POSS) have been explored for over 7 decades. These organic/inorganic nanostructures are extremely versatile compounds that are compartible with polymer systems, hence making them ideal components for the synthesis of next generation hybrid materials. Their properties may vary based on the organic peripheral unit, but they are generally environmentally friendly, cheap, easy to process, highly soluble in organic solvents, and exhibit high thermal degradation temperatures, low dielectric constant and high degree of hardness as coating agents. These features of silsesquioxanes have led to a growing interest in the exploration of their chemistry, particularly on their synthesis and applications in polymer synthesis, catalysis, biomedical materials, and electronics. Cubic silsesquioxanes and their double decker (DDSQ) counterparts have been the most useful because these compounds possess the architecture that accommodates functionalization. However, most of the progress recorded to date has been limited to either manipulations on the closed cubic structures or use of double deckers to synthesize functionally symmetric POSS compound. These compounds do display the desired physicochemical properties, but their applications pose the challenge of tethering them with two dissimilar polymeric chains.In this thesis, efforts have been made to develop a route for the selective synthesis of asymmetric POSS compounds that are likely to provide more resourceful applications to the polymer and material sciences. The research utilized the versatility of protecting groups to effect selective functionalization of the DDSQ for entry into the desired target. The asymmetric POSS cage has the potential to allow its dispersal into two dissimilar polymer matrices, generating a POSS/polymer composite that is unprecedented.

Download or read book Applied Photochemistry written by Rachel C. Evans and published by Springer Science & Business Media. This book was released on 2014-07-08 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Photochemistry encompasses the major applications of the chemical effects resulting from light absorption by atoms and molecules in chemistry, physics, medicine and engineering, and contains contributions from specialists in these key areas. Particular emphasis is placed both on how photochemistry contributes to these disciplines and on what the current developments are. The book starts with a general description of the interaction between light and matter, which provides the general background to photochemistry for non-specialists. The following chapters develop the general synthetic and mechanistic aspects of photochemistry as applied to both organic and inorganic materials, together with types of materials which are useful as light absorbers, emitters, sensitisers, etc. for a wide variety of applications. A detailed discussion is presented on the photochemical processes occurring in the Earth’s atmosphere, including discussion of important current aspects such as ozone depletion. Two important distinct, but interconnected, applications of photochemistry are in photocatalytic treatment of wastes and in solar energy conversion. Semiconductor photochemistry plays an important role in these and is discussed with reference to both of these areas. Free radicals and reactive oxygen species are of major importance in many chemical, biological and medical applications of photochemistry, and are discussed in depth. The following chapters discuss the relevance of using light in medicine, both with various types of phototherapy and in medical diagnostics. The development of optical sensors and probes is closely related to diagnostics, but is also relevant to many other applications, and is discussed separately. Important aspects of applied photochemistry in electronics and imaging, through processes such as photolithography, are discussed and it is shown how this is allowing the increasing miniaturisation of semiconductor devices for a wide variety of electronics applications and the development of nanometer scale devices. The final two chapters provide the basic ideas necessary to set up a photochemical laboratory and to characterise excited states. This book is aimed at those in science, engineering and medicine who are interested in applying photochemistry in a broad spectrum of areas. Each chapter has the basic theories and methods for its particular applications and directs the reader to the current, important literature in the field, making Applied Photochemistry suitable for both the novice and the experienced photochemist.

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.
