Book Description
This book focuses on a variety of photochemical reaction processes in the crystalline state. The crystalline state reaction is a new category of solid state reaction, in which a reaction occurs with retention of the single crystal form. The whole reaction processes were observed directly by X-ray and neutron diffractions. In this book, not only the structures of metastable intermediates, such as radicals, carbenes, and nitrenes, but also the unstable species of photochromic compounds and photo-excited structures are shown with colored figures of the molecular structures, with more than 200 figures. The book is an indispensable resource not only for organic, inorganic and physical chemists but also for graduate students, as it furnishes more than 300 references.

Book Description
Most organic reactions have long been carried out in organic solvents without concern for their real necessity, reaction efficiency, and pollution problems. Very recently, we have found that most organic reactions can be carried out in the absence of a solvent, namely, in the solid state. In many cases, the solid-state reaction proceeds more easily and efficiently, and even more selectively than solution reaction. This shows that molecules move easily and selectively in the solid state. This finding changed the classical idea which suggests "molecules do not move and reactions do not occur in the solid state", and opened up a new research field for the study molecular dynamics in the solid state. The organic solid state reactions have many possibilities to be developed. For example, enantioselective reactions can easily be accomplished by carrying out the reaction in an inclusion complex crystal with an optically active host compound. Catalytic reactions also proceed in the solid state. Moreover, the solid-state reactions are more economical and ecologically sound. In the future, pollution-free synthetic procedures in the solid state will become increasingly important, not only in chemical industries but also in university laboratories.

Book Description
For the last decade, the topics of organic crystal chemistry have become diversified, and each topic has been substantially advanced in concert with the rapid development of various analytical and measurement techniques for solid-state organic materials. The aim of this book is to systematically summarize and record the recent notable advances in various topics of organic crystal chemistry involving liquid crystals and organic–inorganic hybrid materials that have been achieved mainly in the last 5 years or so. The authors are invited members of the Division of Organic Crystals, The Chemical Society of Japan (CSJ), and prominent invited experts from abroad. This edited volume is planned to be published periodically, at least every 5 years, with contributions by prominent authors in Japan and from abroad.

Book Description
This annual review, the 50th volume in the series, provides critical analysis for anyone wanting to keep up to date with the literature on photochemistry and its applications. This essential volume combines reviews on the latest advances in photochemical research with specific topical highlights in the field. The volume starts with periodical reports of the recent literature on organic and computational aspects, including computational advances in photochemistry, chemiluminescence and dark photochemistry, organic aspects of photochemistry of alkenes, dienes and polyenes, aromatic compounds, oxygen-containing functions and those functions containing other heteroatoms, and finally a chapter on transition metal catalysis. Coverage continues in the second part with highlighted topics including photochemical tools for sensing and controlling biological processes, visible light driven enantioselective processes, photochemical formation of C–Chalcogen bonds, photoelectrocatalysis, photovoltaic techniques, photochemical activation of aryl chlorides, luminescent water-soluble systems and computational analyses of fluorescence absorption spectra. This volume will again include a third section entitled ‘SPR Lectures on Photochemistry’, providing examples for academic readers to introduce a photochemistry topic and precious help for students in photochemistry.

Book Description
The breadth of scientific and technological interests in the general topic of photochemistry is truly enormous and includes, for example, such diverse areas as microelectronics, atmospheric chemistry, organic synthesis, non-conventional photoimaging, photosynthesis, solar energy conversion, polymer technologies, and spectroscopy. This Specialist Periodical Report on Photochemistry aims to provide an annual review of photo-induced processes that have relevance to the above wide-ranging academic and commercial disciplines, and interests in chemistry, physics, biology and technology. In order to provide easy access to this vast and varied literature, each volume of Photochemistry comprises sections concerned with photophysical processes in condensed phases, organic aspects which are sub-divided by chromophore type, polymer photochemistry, and photochemical aspects of solar energy conversion. Volume 34 covers literature published from July 2001 to June 2002. Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.

Book Description
In spite of important advances in asymmetric synthesis, chiral compounds cannot all be obtained in a pure state by asymmetric synthesis. As a result, enantiomer separation remains an important technique for obtaining optically active materials. Although asymmetric synthesis is a once-only procedure, an enantiomer separation process can be repeated until the optically pure sample is obtained. This book discusses several new enantiomer separation methods using modern techniques developed by experts in the field. These methods consist mainly of the following three types: 1) Enantiomer separation by inclusion complexation with a chiral host compound 2) Enantiomer separation using biological methods 3) Enantiomer separation by HPLC chromatography using a column containing a chiral stationary phase. Separation of a racemic compound has been called “optical resolution” or simply “resolution”. Nowadays, the descriptions “enantiomer resolution” or “enantiomer separation” are also commonly used. Accordingly, “Enantiomer Separation” is used in the title of this book. The editor and all chapter contributors hope that this book is helpful for scientists and engineers working in this field.
