Book excerpt: Since the last ASI in Turkey in Sept. 1995, the olefin metathesis has made remarkable strong developments with an incredible speed in various directions. New catalyst systems have been developed which have resulted in the synthesis of novel materials. Other fascinating developments have been the new catalysts for stereoselective metathesis and catalysts with considerable functional group tolerance. These new catalysts in addition to Ring Opening Metathesis Polymerisation (ROMP) and Acyclic Diene Metathesis (ADMET) are now powerful tools for Ring Closing Metathesis (RCM) and have found many applications in the synthesis of natural products. A lot of information has been established about all aspects of the olefin metathesis and there is a vast literature concerning the process, covering the initiators, mechanistic features and applications of this reaction in organic and polymer synthesis. The NATO ASI on rd th ROMP and Related Chemistry took place in Polanica-Zdroj, Poland during 3 to 15 Sept. 2000, to highlight the developments in this area and to discuss the prospects and visions for the year 2000 and beyond. The aims of the ASI were: to provide a platform for dissemination of knowledge; to promote communication between people who have a serious interest in this field of chemistry; to help establishing international scientific contacts and to provide an opportunity for the scientists with an appropriate scientific background to learn of recent developments in this field of science. There were 15 lecturers and 67 participants in this NATO ASI.

This book was released on 2010 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ring opening metathesis polymerization (ROMP) is established as one of the efficient controlled living polymerization methods which have various applications in polymer science and technology fields. The research presented in this dissertation addresses several applications of multifunctional well-defined norbornene-based block copolymers synthesized by ROMP using ruthenium-based Grubbs catalysts. These novel block copolymers were applied to stabilize maghemite nanoparticles, creating the superparamagnetic polymeric nanocomposites. The J-aggregation properties of the porphyrin dyes were improved via self-assembly with a customized norbornene polymer. Novel multimodal copolymer probes were synthesized for two-photon fluorescence integrin-targeted bioimaging. In Chapter 1 a brief overview of ROMP along with ruthenium metal catalysts and selected applications of the polymers related to this research is presented. Superparamagnetic maghemite nanoparticles are important in biotechnology fields, such as enhanced magnetic resonance imaging (MRI), magnetically controlled drug delivery, and biomimetics. However, cluster formation and eventual loss of nano-dimensions is a major obstacle for these materials. Chapter 2 presents a solution to this problem through nanoparticles stabiulized in a polymer matrix. The synthesis and chracterization of novel diblock copolymers, consisting of epoxy pendant anchoring groups to chelate maghemite nanoparticles and steric stabilizing groups, as well as generation of nanocomposites and their characterization, including surface morphologies and magnetic properties, is discussed in Chapter 2. In Chapter 3, further improvement of the nanocomposites by ligand modification and the synthesis of pyrazole-templated diblock copolymers and their impact to stabilize the maghemite nanocomposite are presented. Additionally, the organic soluble magnetic nanocomposites with high magnetizations were encapsulated in an amphiphilic copolymer and dispersed in water to assess their water stability by TEM. To gain a preliminary measure of biocopatibility of the micelle-encapsulated polymeric magnetic nanocomposites, cell-viability was determined. In Chapter 4, aggregation behaviors of two porphyrin-based dyes were investigated. A new amphiphilic homopolymer containing secondary amine moieties was synthesized and characterized. In low pH, the polymer became water soluble and initiated the stable J-aggregation of the porphyrin. Spectroscopic data supported the aggregation behavior. Two photon fluorescence microscopy (2PFM) has become a powerful technique in bioimaging for non-invasive imaging and potential diagnosis and treatment of a number of diseases via excitation in the near-infrared (NIR) region. The fluorescence emission upon two-photon absorption (2PA) is quadratically dependent with the intensity of excitation light (compared to the linear dependence in the case of one-photon absoprtion), offering several advantages for biological applications over the conventional one-photon absorption (1PA) due to the high 3D spatial resolution that is confined near the focal point along with less photodamage and interference from the biological tissues at longer wavelength (~700-900 nm). Hence, efficient 2PA absorbing fluorophores conjugated with specific targeting moieties provides an even better bioimaging probe to diagnose desired cellular processes or areas of interest The [alpha subscript v beta subscript 3] integrin adhesive protein plays a significant role in regulating angiogenesis and is over-expressed in uncontrolled neovascularization during tumor growth, invasion, and metastasis. Cyclic-RGD peptides are well-known antagonists of [alpha subscript v beta subscript 3] integrin which suppress the angiogenesis process, thus preventing tumor growth. In Chapter 5 the synthesis, photophysical studies and bioimaging is reported for a versatile norbornene-based block copolymer multifunctional scaffold containing biocompatible (PEG), two-photon fluorescent (fluorenyl), and targeting (cyclic RGD peptide) moieties. This water-soluble polymeric multi scaffold probe with negligible cytotoxicity exhibited much stronger fluorescence and high localization in U87MG cells (that overexpress integrin) compared to control MCF7 cells. The norbornene-based polymers and copolymers have quite remarkable versatility for the creation of advanced functional magnetic, photonic, and biophotonic materials.

Available in PDF, EPUB and Kindle. Book excerpt: Most practitioners and students of polymer chemistry are familiar, in general terms at least, with the established methods of polymer synthesis - radical, anionic, cationic and coordination addition polymerization, and stepwise con densation and rearrangement polymerization. These methods are used to synthesize the majority of polymers used in the manufacture of commercially important plastics, fibres, resins and rubbers, and are covered in most introduc tory polymer chemistry textbooks and in most undergraduate and graduate courses on polymer science. Fewer polymer chemists, however, have much familiarity with more recent developments in methods of polymer synthesis, unless they have been specifically involved for some time in the synthesis of speciality polymers. These developments include not only refinements to established methods but also new mechanisms of polymerization, such as group transfer and metathesis polymerization and novel non-polymerization routes to speciality polymers involving, for example, the chemical modification of preformed polymers or the linking together of short terminally functionalized blocks.

This book was released on 2014 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymeric materials are ubiquitous in numerous facets of everyday life, and their applications will only become increasingly prevalent as the field of polymer science advances. The first chapter of this thesis describes the use of polymeric nanoparticles to overcome challenges in traditional drug delivery. Specifically, a series of novel acid-cleavable bisnorbornene crosslinkers were synthesized and evaluated as building blocks for the formation of acid-degradable brush-arm star polymers (BASPs) via the brush-first ring-opening metathesis polymerization (ROMP) method. A bis-norbornene acetal structure was identified that, when employed in conjunction with a poly(ethylene glycol) (PEG) macromonomer, provided highly controlled BASP formation reactions. Combination of this new crosslinker with a novel acid-labile doxorubicin (DOX)-branch-PEG macromonomer provided BASPs that simultaneously degrade and release DOX in cell culture. In vitro cell viability studies using HeLa cells confirmed that these constructs are cytotoxic. Even though polymeric materials have found widespread use in current times, polymer science must overcome certain challenges to contend with the needs of next-generation technologies. In particular, newer polymer applications require the use of macromolecules with precisely defined structure and degree of polymerization--challenges that synthetic polymer chemistry has yet to conquer. The second chapter of this thesis describes a novel synthetic methodology (IEG+) that gives polymers with defined molar mass and sequence using synthetic procedures that are precise, scalable, and amenable to diversification. The IEG+ method utilized monomers equipped with orthogonal protecting groups: epoxides and alkynyl silanes. The epoxide functionality served both as a protecting group and as a masked synthon for alcohols, which allowed for side-chain functionalization of the IEG+ scaffold. Combing R- and Smonomers afforded complete stereochemical control of the IEG backbone. Oligomers of unimolecular molar mass and precise chemical structure were successfully prepared.

This book was released on 2021 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the work that is done in polymer chemistry are performed through the creative use of well understood polymers and reactions. With the introduction of novel methods for polymer synthesis being few and far between. This thesis discusses the investigation of introducing new strategies for the synthesis of novel polymers and the attempts to understand their behavior. In Chapter 2, the synthesis and ring-opening metathesis polymerization (ROMP) of a unique macrocyclic stilbene-based monomer. Ultimately, we found that high initiation efficiency was achieved, and that the rate of chain transfer was competitive with propagation during polymerization. We discuss the modular synthesis of the monomer, ROMP kinetics, attempts to limit the rate of chain transfer, and potential applications of this new system. Chapter 3 and 4 investigated the synthesis of monomers that utilize the hetero-Diels-Alder reaction in a step-growth polymerization. The targeted monomers can facilitate the synthesis of both linear polymers and covalent adaptable networks. Ultimately, we found that the solubility of the monomers inhibits the synthesis of the of the polymer networks. We will also discuss the synthesis and its complications as well as potential solutions for these limitations. In Chapter 5, the mechanochemical reactivity of 1,2-oxazines is explored and how different isomers impact the rate of mechanical activation. Finally in Chapter 6, we explore methods for the synthesis of amphiphilic block copolymers to act as polyelectrolytes for the development of moisture resistant super gas barriers.
