Photochemistry in Microheterogeneous Systems provides an introduction to the subject of photochemistry in microheterogeneous systems. Emphasis is on the unimolecular and bimolecular reactions of electronically excited molecules in non-homogeneous media, as well as the application of photophysical and photochemical processes and techniques to the study of various microheterogeneous systems of chemical and biological interest, from normal and inverted micelles to vesicles and liposomes, monolayers, black lipid membranes, and liquid crystalline solvents. This monograph is comprised of 10 chapters and begins with an overview of microheterogeneous systems; excited-state processes and reactions; photochemistry in microheterogeneous systems; and structural and dynamical aspects of micellar aggregates. The discussion then turns to micellar photophysics and photochemistry, with emphasis on singlet-state and triplet-state reactions. Subsequent chapters focus on photoprocesses in a variety of microheterogeneous systems such as reversed micelles, microemulsions, lipids, surfactant vesicles, and liposomes; polymers, polyelectrolytes, and ion-exchange membranes; and molecular inclusion complexes. The final chapter is devoted to the photochemistry of molecules in the adsorbed state. This text is intended for graduate students and practicing chemists.

Photosensitization and photocatalysis refer to processes by which permanent chemical transformations are induced on substrates (organic/inorganic) by radiation to which the substrates themselves are transparent. Such transformations can be highly specific, very efficient, and occur under mild conditions. Herein lies the power of photochemical methods for possible applications in the field of conversion and storage of solar energy. This book provides a recent survey of the progress in this important area in catalysis, with an emphasis on inorganic complexes and organometallic compounds as the key light aborbers. The book is organized in three parts: fundamentals, followed by applications. Discussions cover a wide variety of photosensitized or photocatalyzed reactions: decomposition of water, reduction of CO2 and CO; spectral sensitization in photoelectrochemical cells; transformations (oxidation, reduction, isomerization, hydrogenation, dehydrogenation, carbonylation, etc.) of organics such as alkanes, alkenes, alcohols, etc.In view of the variety of systems (sensitizers, substrates) and the topics covered, the volume is unique in the field of photochemistry and will appeal to academic and industrial researchers in various subdisciplines of chemistry, material science and catalysis.
