Complex Macromolecular Architectures

The field of CMA (complex macromolecular architecture) stands at the cutting edge of materials science, and has been a locus of intense research activity in recent years. This book gives an extensive description of the synthesis, characterization, and self-assembly of recently-developed advanced architectural materials with a number of potential applications. The architectural polymers, including bio-conjugated hybrid polymers with poly(amino acid)s and gluco-polymers, star-branched and dendrimer-like hyperbranched polymers, cyclic polymers, dendrigraft polymers, rod-coil and helix-coil block copolymers, are introduced chapter by chapter in the book. In particular, the book also emphasizes the topic of synthetic breakthroughs by living/controlled polymerization since 2000. Furthermore, renowned authors contribute on special topics such as helical polyisocyanates, metallopolymers, stereospecific polymers, hydrogen-bonded supramolecular polymers, conjugated polymers, and polyrotaxanes, which have attracted considerable interest as novel polymer materials with potential future applications. In addition, recent advances in reactive blending achieved with well-defined end-functionalized polymers are discussed from an industrial point of view. Topics on polymer-based nanotechnologies, including self-assembled architectures and suprastructures, nano-structured materials and devices, nanofabrication, surface nanostructures, and their AFM imaging analysis of hetero-phased polymers are also included. Provides comprehensive coverage of recently developed advanced architectural materials Covers hot new areas such as: click chemistry; chain walking; polyhomologation; ADMET Edited by highly regarded scientists in the field Contains contributions from 26 leading experts from Europe, North America, and Asia Researchers in academia and industry specializing in polymer chemistry will find this book to be an ideal survey of the most recent advances in the area. The book is also suitable as supplementary reading for students enrolled in Polymer Synthetic Chemistry, Polymer Synthesis, Polymer Design, Advanced Polymer Chemistry, Soft Matter Science, and Materials Science courses.

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 describes techniques of synthesis and self-assembly of macromolecules for developing new materials and improving functionality of existing ones. Because self-assembly emulates how nature creates complex systems, they likely have the best chance at succeeding in real-world biomedical applications. • Employs synthetic chemistry, physical chemistry, and materials science principles and techniques • Emphasizes self-assembly in solutions (particularly, aqueous solutions) and at solid-liquid interfaces • Describes polymer assembly driven by multitude interactions, including solvophobic, electrostatic, and obligatory co-assembly • Illustrates assembly of bio-hybrid macromolecules and applications in biomedical engineering

An overview of the latest advances in the synthesis, characterization and applications of dendrimers and other complex dendritic architectures.

This volume summarizes the papers presented at the second Osaka University Macromolecular Symposium OUMS '95 on "New Macromolecular Architecture and Functions" which was held at Senri Life Science Center, Osaka, Japan, on June 2 through June 5, 1995. The symposium covered the three topics, (1) Controlled Polymerizations, (2) Macromolecular Organized Systems and (3) Biomimetic Polymers, and invited leading scientists in these fields. At present, any of these topics is a hot issue in itself and frequently taken up separately on many occasions. It is noted, however, that all these topics are correlated with each other with the keyword "molecular design of new types of polymers" and their combination provides a unique feature of the present symposium in reflecting the interactions among investigators working in these important fields with the common ground expressed by the keyword "molecular design of new types of polymers". Twenty five invited lectures and twenty nine posters were presented at the Symposium, and twenty of the lectures contribute to this volume. In the first topic, preparations of sequentially of stereoregularly controlled polymers were discussed from the view points of precise design of polymer preparation on the molecular level; attention was paid to a possibility of living radical polymerization, preparations of new types of living polymers, recent advances in preparation of stereospecific living polymers, sequential control in block copolymers, and molecular design of initiators and/or catalysts for the controlled polymerizations.
