Available in PDF, EPUB and Kindle. Book excerpt: Efficient and versatile catalytic chemistry has continuously stimulated the syntheses of novel materials. This thesis describes the syntheses of non-linear polymers and anti-aromatic conjugated molecules using catalytic arene-norbornene annulation reactions and metathesis polymerizations. Bottlebrush polymers have a very high density of side chains grafted to the backbone, leading to an extended worm-like conformation. Efficient, modular synthesis of brush polymers is the first step for thorough understanding of their solution and assembly behaviors and to enable various applications. In the first part of this thesis, we investigated the limitations of the previous methods used for brush polymer synthesis. We further developed a streamlined one-pot macromonomer synthetic strategy to synthesize well-defined brush (co)polymers via ring-opening metathesis polymerization (ROMP). In the pursuit of facile methods for the synthesis of rigid ladder structures, we have developed Catalytic Arene-Norbornene AnnuLation (CANAL) chemistry to couple aryl bromides with norbornenes (NBEs) to form rigid fused norbornyl benzocyclobutene ladder structures. In the second part of this thesis, we utilized this efficient chemistry to synthesize various polymeric materials and conjugated molecules containing rigid ladder motifs. We first demonstrated the synthesis of polyladders via ROMP of rigid CANAL ladder oligomer to provide porous polymers with high solution processability. We further developed an efficient strategy to prepare star polymers cross-linked via telechelic CANAL ladder using ROMP. The arms of these star polymers can be readily cleaved under acidic conditions to allow isolation of soluble microporous organic nanoparticles. In another manifestation of CANAL chemistry, when oxaNBEs are used in place of NBEs, the CANAL products can be aromatized to form conjugated systems with fused four-membered rings. The conjugated four-membered rings also elicit antiaromaticity arising from cyclobutadienoid (CBD). Non-benzenoid structures with antiaromaticity have been much less explored with limited understanding of their properties due to the challenging synthesis. We developed a modular and streamlined CANAL-aromatization strategy to synthesize a series of polycyclic conjugated hydrocarbons containing CBDs. We further extended this CANAL-aromatization strategy to synthesize a series of regioisomeric CBD-fused phenazines and investigated the effect of bond fusion pattern on local antiaromaticity.

Book Synopsis Chirality from Molecular Electronic States by : Takashiro Akitsu
Download or read book Chirality from Molecular Electronic States written by Takashiro Akitsu and published by BoD – Books on Demand. This book was released on 2019-02-06 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: In chemistry, biology, and physics, "chirality" is an important concept in nature. Especially in chemistry, not only classical stereochemistry but also asymmetric organic synthesis, supramolecular chemistry, construction of bio-related molecules and molecular recognition became indispensable structural chemical keywords. However, in view of synthetic chemistry and its structural chemistry, chemistry dealing with chirality in relation to the more fundamental electronic state is still a minority. This book is particularly aimed at chiroptical spectroscopy, structural or physical features and theoretical computation of chirality.

Book Synopsis Self-Healing Polymers by : Wolfgang H. Binder
Download or read book Self-Healing Polymers written by Wolfgang H. Binder and published by John Wiley & Sons. This book was released on 2013-03-29 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-healing is a well-known phenomenon in nature: a broken bone merges after some time and if skin is damaged, the wound will stop bleeding and heals again. This concept can be mimicked in order to create polymeric materials with the ability to regenerate after they have suffered degradation or wear. Already realized applications are used in aerospace engineering, and current research in this fascinating field shows how different self-healing mechanisms proven successful by nature can be adapted to produce even more versatile materials. The book combines the knowledge of an international panel of experts in the field and provides the reader with chemical and physical concepts for self-healing polymers, including aspects of biomimetic processes of healing in nature. It shows how to design self-healing polymers and explains the dynamics in these systems. Different self-healing concepts such as encapsulated systems and supramolecular systems are detailed. Chapters on analysis and friction detection in self-healing polymers and on applications round off the book.
