Advances In Dendritic Macromolecules

The series Advances in Dendritic Macromolecules aims to cover the synthetic, as well as chemical, aspects of this expanding field: the chemistry to and supramolecular chemistry of dendritic or cascade supermolecular compounds. In Chapter 1 of this volume, Hawker and Wooley delineate the convergent growth approach to dendrimers, then relate their three-dimensional architectures to different block polymers. In Chapter 2, Moors and Vögtle describe Professor Vögtle's initial cascade molecules via the repetitive strategy, then expand his original concepts of its application by others, and lastly delineate the synthesis of a new series of tosylamide cascades. They also demonstrate the utility of his original Michael addition/reduction procedure by its application to differ cores. Chapter 3, composed by Professor Engel, describes ionic dendrimers which incorporated an internal transition metal center as well as his work based on ammonium and phosphonium centers. In Chapter 4, Mathias and Carothers review recent studies on silicon-based dendrimers and hyperbranched polymers. Chapter 5, by Kim, describes the preparation and utility of hyperbranched aromatic polymers. Lastly in Chapter 6, Escamilla reviews the historical as well as recent examples of ionic and nonionic bolaamphiphiles.

The series Advances in Dendritic Macromolecules aims to cover the synthesis and supramolecular chemistry of dendritic or cascade super-molecules as well as their less perfect hyperbranched cousins. The field of hyperbranched macromolecules, specifically dendrimers, has continued to expand at an amazing rate. The synthetic aspects, which were assumed to be over several years ago, have opened new avenues into the mesomolecular regime. The synthetic ingenuity of chemical artists has afforded new monomers and their diverse combinations to give rise to (poly)functionalized materials that embrace new supramolecular concepts in areas such as molecular recognition, assembly, encapsulation, and inclusion; catalysts; coatings; drug delivery systems; and in essence opens up the field of suprasupermolecular chemistry. In chapter 1 the synthesis of organometallic and related transition metal-cotaining dendrimers is summarized and their novel properties and useful applications are described. Chapter 2 covers work on the commercial poly(propylene imine)s, including the "dendritic box", dendrimer-based superamphiphiles, and unimolecular inverse micelles. The next chapter looks at aspects of chirality in dendritic systems and this is followed by a look inside dendrimers from a molecular topologist's point-of-view.

This important work is based on the editors’ symposium at the 2005 ACS meeting in Washington, DC. The contents include an emphasis on main-group polymers, including boron. The chapters are not simply journal articles, but have real added value as the editors have reviewed the general area by placing the work into a larger perspective. This book will be required reading for scientists in a number of disciplines including chemical engineers and physics researchers.

The first book on dendrimers! The authors, pioneers in this scientific field, describe basic principles and current developments in the rapidly evolving field of dendrimer research. All aspects of the subject are covered: the authors provide a historical overview, theoretical background, and discussions of the synthesis and applications of dendrimers. The book thus spans organic chemistry and more application-orientated disciplines like material science and pharmaceutical chemistry. The excellent, detailed list of references further increases the value of the book. The optimal presentation of the structural formulas of dendrimers - highly symmetrical giant molecules - helps the reader understand the sophisticated synthesis quickly. This book will set the standard for further monographs on this subject.

Presents a comprehensive and interdisciplinary review of the majorcutting-edge technology research areas—especially those onnew materials and methods as well as advanced structures andproperties—for various sensor and detection devices The development of sensors and detectors at macroscopic ornanometric scale is the driving force stimulating research insensing materials and technology for accurate detection in solid,liquid, or gas phases; contact or non-contact configurations; ormultiple sensing. The emphasis on reduced-scale detectiontechniques requires the use of new materials and methods. Thesetechniques offer appealing perspectives given by spin crossoverorganic, inorganic, and composite materials that could be uniquefor sensor fabrication. The influence of the length, composition,and conformation structure of materials on their properties, andthe possibility of adjusting sensing properties by doping or addingthe side-groups, are indicative of the starting point ofmultifarious sensing. The role of intermolecular interactions,polymer and ordered phase formation, as well as behavior underpressure and magnetic and electric fields are also important factsfor processing ultra-sensing materials. The 15 chapters written by senior researchers in AdvancedSensor and Detection Materials cover all these subjects and keyfeatures under three foci: 1) principals and perspectives, 2) newmaterials and methods, and 3) advanced structures and propertiesfor various sensor devices.

Dendrimers are a class of highly branched molecules that combine the properties of polymers and small discrete molecules. One classified among the exotic molecules of chemistry, dendrimers have attracted considerable attention in recent years, as their unique host/guest properties and their capability of being functionalized in the periphery as well in the core have led to new materials with a great potential for applications. This volume presents the state of art in this blossoming area, written by pioneers in the fields. Covering the synthetic, supramolecular, stereochemical, host/guest and polymer chemistry of dendritic and hyperbranched molecules, this volume explains both theoretical and practical aspects, including chirality reactivity, mechanism, material properties and biological relevance.

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