Dendrimers Iii

Dendrimers are a class of highly branched molecules that combine the properties of polymers as well as 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 research 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. It is the most comprehensive and authoritative review of the area available.

Following the first two volumes "Dendrimers" (TCC vol. 197) and "Dendrimers II" (TCC vol. 210), the third volume dealing with this topic is now appearing in print (the "tetralogy" on dendrimers will soon be completed with the fourth volume). The present volume comprises a collection of up-to-date reviews written by renowned pioneers of research in the dendrimer field, three of whom lectured at the 1. International Dendrimer Symposium (IDS-1 1999) in Frankfurt. A focus of this volume is the variety of material properties of soft and shape-persistent dendrimers. As its predecessors did, this volume breaks through the frontiers to neighboring disciplines and, in an interdisciplinary approach, addresses topics such as polydisperse, hyperbranched macromolecules (dendritic polymers), the analysis of shape and density by small-angle scattering techniques, finely dispersed metals (dendrimers as catalysts), and nanotechnology close to potential applications.

With contributions from many of the world's leading scientists in the field of dendritic research and development, Dendrimers and Other Dendritic Polymers provides a comprehensive review of this rapidly expanding and exciting new field of polymer science. Of interest to academia and industry alike, this book covers the synthesis, characterization, unique properties, potential for novel applications and technical challenges associated with these polymers. * Detailed coverage of all known subclasses of dendritic polymers, including their properties and synthesis * Insight into the potential commercial applications of dendritic polymers, including drug delivery, cancer therapy, coatings and adhesives * Identification of the key trends and perspectives in dendrimer research * Essential reference for polymer chemists, materials scientists and plastics engineers working in academia and industry alike

The second volume on dendrimers is again written by pioneers in the field. Their contributions illuminate the aspects of dendrimers mentioned in the subtitle, and also touch on areas beyond chemistry, namely material sciences as well as biological, medicinal, analytical, and nano aspects.

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.This volume demonstrates the novel and varied growth in this topic and certainly pushes the supramolecular concepts of Lehn into the budding "supramacro-molecular" frontier. In Chapter 1, Villavicenio and McGrath present their pivotal work in the creation of azobenzene-containing dendrimers; their Chapter describes the fundamental underpinnings to this interesting family. As they state in their summation, "A continuing combination of fundamental studies on the photomodulation of dendrimer properties in azobenzene-containing dendrimers and the new developments in the application of these materials to new and existing technologies is anticipated." The field of linear - dendritic block copolymers is summarized inChapter 2 from the eyes of Ivan Gitsov, who along with Professor Fréchet were the initiators of this variety of macromolecules.In Chapter 3, Astruc and colleagues present the recent advances in metallodendrimers, which incorporate ferrocenyl and/or other transition metal sandwich components; their Chapter capitalizes on the importance of supramolecular chemistry in these dendritic constructs.Finally, in Chapter 4, Wiener and Narayanan describe the practical applications of dendrimers to the area of magnetic resonance imaging contrast agents. Each of these unique chapters covers a different perspective of this versatile group of macromolecules.

Dendrimers are defined as nanoscale macromolecules having a particular architecture consisting of treelike arms or branches. They are characterized by special properties that make them promising candidates in medicine, biology, materials science, synthetic organic chemistry, biotechnology, environmental engineering, optics, electronics, catalysis, electrochemistry, photochemistry, and sensors and even for production of cosmetics and personal care products. The dendrimers research field is growing day by day, and scientists are exploring new synthesis and functionalization methods in order to improve and to determine new properties and thus new applications. The main purpose of this book is to highlight the issues regarding properties and applications of dendrimers in the field of biology, medicine, liquid crystal devices, electronics, quantum devices, and self-healing technology.

With chapters from highly skilled, experienced, and renowned scientists and researchers from around the globe, Dendrimers for Drug Delivery provides an abundance of information on dendrimers and their applications in the field of drug delivery. The volume begins with an introduction to dendrimers, summarizing dendrimer applications and the striking features of dendrimers. It goes on to present the details of usual properties, structure, classification, and methods of synthesis, with relevant examples. The toxicity of dendrimers is also discussed. The chapter authors provide an exhaustive amount of information about dendrimers and their biomedical applications, including biocompatibility and toxicity aspects, a very useful feature. This informative volume will be valuable resource that will help readers to create products derived from dendrimers and navigate through the regulatory, manufacturing, and quality control hurdles. It will be an important resource for researchers, scientists, upper-level students, and industry professionals.

Dendrimers are a new class of macromolecule increasingly used in the fields of synthetic organic chemistry, biology, medicine and biotechnology. Dendrimers in Medicine and Biotechnology: New Molecular Tools looks at this exciting and rapidly growing area of science. Using an interdisciplinary approach with particular emphasis on biological applications, the book discusses the relationship between the dendrimer molecular motif and its biological properties. A general introduction to the subject of dendrimers, including definitions of terms and symbols, is provided. Subsequent sections discuss topics including dendrimers in biological systems, dendrimers as drug delivery devices, dendrimers in diagnostics and dendrimer drugs. Throughout the book examples from current research are also provided. This book will appeal to a wide range of scientists, including non specialists who require an introduction to dendrimers, as well as those wishing to know more about the application of dendrimers in the field of biology and medicine.
