Control of molecular chirality is central to contemporary chemistry, biology, and materials-related areas. Chiral photochemistry employs molecular and supramolecular chiral interactions in the electronically excited state to induce molecular chirality, providing new and versatile strategies and surprising results unattainable by conventional thermal asymmetric synthesis. Chiral Photochemistry is the first book devoted solely to this rapidly growing area. This comprehensive and authoritative book covers all aspects of the subject, from circularly polarized light to supramolecular chiral source and from the origin of homochirality in the biosphere to chiral devices and materials.

This text discusses di-p-methane rearrangements via radical-cation intermediates, the photo-Fries rearrangement in organized media and of biologically active compounds, electron transfer leading to fragmentation, dimerization, and nucleophilic capture, and the characterization and reactivity of photochemically generated phenylene bis(diradical) species. The authors reveal experimental and computational techniques for the study of phenylene-linked carbenes and nitrenes. Brimming with over 900 references, Photochemistry of Organic Molecules in Isotropic and Anisotropic Media is crucial for professionals and students in photochemistry; chemical engineering; materials and semiconductor science; and organic, inorganic, and physical chemistry.

A consideration of the development of photochemical systems with functions as optical sensors or switches, discussing materials and chemical systems, technology, and applications for target molecules and optical signal multiplexing. It contains novel applications in electrogenerated chemiluminescence and supramolecular photophysics for sensing chemical and biological analytes.

This text examines organic, physical and materials photochemistry. It reports the first example of a TiO2 sensitization with a fullerene-based donor-acceptor dyad, and covers halophenols, diflusinal photochemistry, hydroxystyrenes, acetylenes, and other related compounds. The volume also investigates whether c,d-alkenes influence the efficiency and course of light-induced reactions, and more.

Answering the need for information that could revolutionize the development of alternate solar energy sources and the reduction of atmospheric contaminants, Semiconductor Photochemistry and Photophysics reflects renewed interest inspired by the unique properties of nanocrystalline semiconductor particles. It provides a thorough overview and describes fundamental research aimed at understanding the underlying mechanisms of the cells and looks at the application of nanocrystalline TiO2 as a photocatalyst for environmental remediation. Key topics include semiconductor photoelectrochemistry, dye-sensitized solar cells, and photocatalytic treatment of chemical waste.

Featuring contributions from leading experts, Organic Photochemistry and Photophysics is a unique resource that addresses the organic photochemistry and photophysical behavior in aromatic molecules, thiocarbonyls, selected porphyrins, and metalloporphyrins.The book presents theories pertaining to radiative and radiationless transitions. It describes excited-state proton-transfer reactions of aromatic compounds and the physical, energetic, and environmental effects of atom transfer reactions. The text discusses the role of the carbonyl and azo groups in ketones and azoalkanes in the development of photochemistry, followed by a review of nucleophilic substitution reactions in the photochemistry of aromatics (also called photosubstitution) and the various atomic bonds that result from these reactions. The book presents studies that explain the factors that govern the nature and efficiencies of SET-promoted photochemical reactions. It then focuses on photoamination as a convenient, powerful, and environmentally friendly synthetic process for transforming a variety of substrates into the corresponding aminated compounds. The final chapter explores how dye structure affects the sequence-dependence of DNA binding, which has potential applications in nonlinear optics and DNA detection as well as incorporating DNA into various nanostructures and devices.With an emphasis on the current uses of light in both materials chemistry and medicinal chemistry, this book serves as a comprehensive resource on photochemical reactions and discusses topics that are useful for researchers as well as newcomers in the fields of photochemistry, photobiology, photomedicine, and photophysics
