his book describes synthetic methods for organic chromophores used in optoelectronic applications. It emphasizes the design and synthesis of (electron donor)-(π-bridge)-(electron acceptor) systems, including improving processing and thermo-optical stability. Chapter 1 includes a history of organic electronics and photonics, including lightemitting diodes, field-effect transistors, nonlinear optics, electro-optics, and photovoltaics. Chapter 2 discusses chromophore design. The authors correlate the optical gap, ionization energy, and electron affinity with descriptors, including Hammett-type parameters, aromaticity indices, and frontier orbital energies. They give strategies for improving processability, followed by a discussion of the relation of intermolecular interactions and charge-transport properties. The remainder of the book discusses methods to synthesize the designed chromophores. All of the chapters explain underlying reaction mechanisms and
give numerous examples. Chapter 3 includes methods for donor materials synthesis, specifically thiophenes and aryl amines. There is extensive discussion of the safe use of lithium reagents for preparation of various thiophenes. There is also discussion of Grignard reagents, alkylation reactions, thiophene rings, and heteroannulation synthesis. Chapter 4 deals with the creation of π-conjugated bridges between aromatic intermediates. The reactions discussed include halogenation, Vilsmeier formylation, use of phosphorus reagents, and the Horner–Wadsworth–Emmons reaction. Chapter 5 describes organometallic coupling chemistry. The basic reactions of ligand exchange, oxidative addition, reductive elimination, migratory insertion, and β-hydride elimination are covered, followed by a discussion of the Stille, Kumada, Negishi, Sonogashira, and Heck coupling reactions. Chapter 6 discusses synthesis of acceptors. There is a discussion of

his book falls into Elsevier’s Micro & Nano Technologies Series. As a teacher who taught a course on microsensors and actuators for over 10 years, I always saw the need for having a book on electrochemical micromachining (EMM) techniques containing good
illustrations. Classical books cover this topic in a few pages without emphasizing the principles. Electrochemical machining (ECM) is a topic that requires greater emphasis as a potential method by which devices can be fabricated. It provides continuous production schemes
Knoevenagel condensation as well as the chemistry of polymethine dyes, including hemicyanines, merocyanines, and cyanines. Other types of acceptors presented are tetracyanoethylenes, heterocycles, thiadiazoles, pyrazines, diketopyrrolopyrroles, isoindigos, and imides. Chapter
