D. Mendenhall - Böcker

This book provides readers with examples of the synthesis and applications of large molecules and molecular assemblies designed for their unusual shapes or forms, or for some analytical or synthetic purpose. The chapters address the differing concepts of molecules and materials. Numerous references to original literature and to reviews are included. The topic of synthetic dendrimers is presented along with a novel descriptive system (fractal notation), with which complicated but regularly-shaped molecules may be described in a highly condensed fachion. The authors include individuals who have published extensively in the fields of the various chapters. The volume is appropriate as a primary text in a specials topics course in advanced organic or polymer chemistry, or as a supplementary text for these courses or for materials sciences courses. This book should be of interest to advanced graduates and graduate students in chemistry and related disciplines; and academic, industrial and government scientists in organic, inorganic, polymer and physical chemistry, biomedical and material sciences.

The title of this volume implies a progression of sorts from species of molecular size to a product described on the basis of continuum prop­ erties. The difference in approach from the standpoint of molecular be­ havior, on the one hand-more the forte of chemists-and from the standpoint of large-scale properties, on the other-more the province of chemical engineers and materials scientists-represents a severe cultural divide, but one with much potential for creative input from both sides. Chapter 1 of this volume attempts a broad survey of trends toward the synthesis of large, well-defined molecular systems with interesting physical, chemical, or material properties. Review articles with more de­ tailed treatments are emphasized. In Chapter 2, Newkome and Moore­ field summarize work on synthesis of /I cascade" molecules. Next, Denti, Campagna, and Balzani describe the synthesis of assemblies with con­ nected metal-containing chromophore units which transmit electrons or electronic energy in defined ways. In Chapter 4 Wuest describes the con­ struction of hydrogen-bonded organic networks, and in Chapter 5 Michl defines a molecular-level construction set. Finally, Jaszczak points out how nature's attempts over geological time spans are emulated by recent human synthetic activity in the fullerene arena, through the appearance of various morphologies of natural graphite. The book concludes with a method for describing fractal-like mole­ cules, and an index based on the method for appropriate compounds described in the text.
