Hierarchical Bottom-Up Methodology for Integrating Dynamic Ethynylhelicene Oligomers by Nozomi Saito Pdf

In biological systems, molecules hierarchically form ordered assemblies and macroscopic substances, as exemplified by the assembly of proteins. The development of such systems using oligomeric macromolecules obtained by organic synthesis can provide insights into biological phenomena and will lead to the creation of new materials. In this regard, synthetic double helix molecules are attractive subjects of study because they have an important structural motif that appears widely in nature and can exhibit dynamic structural change. This thesis describes an unprecedented bottom-up approach using synthetic ethynylhelicene oligomers, which form dynamic double helices in organic media. Oligomer synthesis, homo- and hetero-double helix formation, and higher assembly formation due to intercomplex interactions are documented. The hierarchical assembly formation is a cogent reminder of the assembly of biological proteins that create living creatures. Also notable here is the demonstration of a methodology of providing diverse hetero-double helices and their higher assemblies by changing the combination of oligomers, which can be another advantage of this synthetic system.

Polymorphism in Molecular Crystals by Joel Bernstein Pdf

Polymorphism - the multiplicity of structures or forms - is a term that is used in many disciplines. In chemistry it refers to the existence of more than one crystal structure for a particular chemical substance. The properties of a substance are determined by its composition and by its structure. In the last two decades, there has been a sharp rise in the interest in polymorphic systems, as an intrinsically interesting phenomenon and as an increasingly important component in the development and marketing of a variety of materials based on organic molecules (e.g. pharmaceuticals, dyes and pigments, explosives, etc.). This book summarizes and brings up to date the current knowledge and understanding of polymorphism of molecular crystals, and concentrates it in one comprehensive source. The book will be an invaluable reference for students, researchers, and professionals in the field.

Graphene Oxide by Ayrat M. Dimiev,Siegfied Eigler Pdf

Due to its unique properties, graphene oxide has become one of the most studied materials of the last decade and a great variety of applications have been reported in areas such as sensors, catalysis and biomedical applications. This comprehensive volume systematically describes the fundamental aspects and applications of graphene oxide. The book is designed as an introduction to the topic, so each chapter begins with a discussion on fundamental concepts, then proceeds to review and summarize recent advances in the field. Divided into two parts, the first part covers fundamental aspects of graphene oxide and includes chapters on formation and chemical structure, characterization methods, reduction methods, rheology and optical properties of graphene oxide solutions. Part Two covers numerous graphene oxide applications including field effect transistors, transparent conductive films, sensors, energy harvesting and storage, membranes, composite materials, catalysis and biomedical applications. In each case the differences and advantages of graphene oxide over its non-oxidised counterpart are discussed. The book concludes with a chapter on the challenges of industrial-scale graphene oxide production. Graphene Oxide: Fundamentals and Applications is a valuable reference for academic researchers, and industry scientists interested in graphene oxide, graphene and other carbon materials.

Circular Dichroism and Linear Dichroism by Alison Rodger,Bengt Nordén Pdf

This book provides an introduction to all those who wish to use the complementary spectroscopic techniques of optical activity (circular dichroism, CD) and optical anisotropy (linear dichroism, LD) for the study of the structure of molecules and interactions between molecules in solution. It emphasizes these techniques and how to use them for both low and high molecular weight molecules. The book begins by describing the principles behind CD and LD and how these techniques can be used in the laboratory without using advanced maths or quantum mechanics. The next chapters describe how both techniques may be applied to the study of biological macromolecules and give a detailed description of how they may be used on small molecules to investigate molecular and electronic structure. The final part contains theoretical derivations of all the equations required for the applications described previously. Specific molecular examples are used to illustrate concepts and to show the reader how to use the techniques in chemical and biological systems. Circular Dichroism and Linear Dichroism is an easy guide to what a prospective user of CD needs to know and explains how LD is not merely an exotic technique only to be practiced by experienced spectroscopists, but may be routinely and usefully employed as an aid to molecular structure determination.

Linear Dichroism and Circular Dichroism by Bengt Nordén,Alison Rodger,Tim Dafforn Pdf

This book provides an introduction to optical anisotropy (linear dichroism, LD) and optical activity (circular dichroism, CD) as techniques for the study of structures and interactions of molecules in solution. The book covers the use of these techniques for both small and large molecular systems with particular emphasis being placed on proteins and nucleic acids. CD is a well-established technique and this book aims to explain how it can be used simply and effectively for new entrants to the field as well as covering more advanced techniques for experts. LD is often seen as a rather exotic method intended only for experienced spectroscopists. This book demonstrates that it is an approach with real utility that may be used by both students and scientists from graduate level onwards to give simple answers, which are not available from any other technique, to structural and kinetic questions. Much of the emphasis is on flow orientation of samples in solution phase. The book first describes the techniques and the information they can provide; it then goes on to give specific details on how to actually implement them, including a wide range of examples showing how LD and CD can help with * protein and nucleic acid secondary structure elucidation; * analysis of the formation and rearrangements of fibrous proteins and membrane proteins; * identification of the absolute configuration of small molecules; * determination of the orientation of small molecules in anisotropic media; * assignment of transition moment polarizations; * investigation of binding strengths and geometries of ligand-macromolecule complexes; * 3-D structure determination from LD, molecular replacement and MD modeling. The advantages of combined LD/CD studies are also outlined with examples of DNA/drug complexes and protein insertion into membranes. Taken together the book represents a comprehensive text on the theory and application of LD and CD in the chemical and biological sciences.
