Photochromism is the reversible phototransformation of a chemical species between two forms having different absorption spectra. During the phototransformation not only the absorption spectra but also various physicochemical properties change, such as the refractive index, dielectric constant, oxidation/reduction potential, and geometrical structure. The property changes can be applied to photonic equipment such as erasable memory media, photo-optical switch components, and display devices. This book compiles the accomplishments of the research project titled “New Frontiers in Photochromism” supported by the Ministry of Education, Culture, Sports, Science and Technology of Japan. The project focused not only on the above-mentioned classical subjects in photochromism, such as color changes, optical memory, and optical switches, but also on fundamental physicochemical studies and unprecedented application fields that have not yet been explored in photochromism. The latter topics include light-driven mechanical motion, photocontrol of surface wettability, metal deposition on solid materials, photocontrol of chiral properties, ultrafast decoloration dyes, and femtosecond laser experiments, among others.

A comprehensive overview about the emerging field of photoswitches and their applications in materials science and biology Molecular Photoswitches guides the reader through the basic molecular structures of photochromic compounds and their applications in the area of photoresponsive materials as well as in the biological context. The initial chapters describe individual classes of molecular photoswitches, introducing their principles of photochromism, typical switching wavelengths, thermal stability of photoisomers and other key information, which is ordinarily spread in the literature. These classes comprise i.a. azobenzenes, diazocines, arylazoheterocycles, arylhydrazones, indigoids, photochromic imines, or acylhydrazones. The book also covers: Catalysis with molecular switches Applications in photochromic porous materials, liquid crystals, or nanoparticles Light-responsive molecular machines, logic devices, and molecular magnets Photomodulation of biological systems: photoswitchable biopolymers, lightmodulated antibiotics, cytotoxins, ion channel inhibitors, light-propelled artificial muscles, and computationally designed photochromic proteins This two-volume work is a valuable guide for researchers and non-experts working in the field of photochemistry, organic chemistry, catalysis, materials science, biology, and medicine.

Anion recognition plays a critical role in a range of biological processes, and a variety of receptors and carriers can be found throughout the natural world. Chemists working in the area of supramolecular chemistry have created a range of anion receptors, drawing inspiration from nature as well as their own inventive processes. This book traces the origins of anion recognition chemistry as a unique sub-field in supramolecular chemistry while illustrating the basic approaches currently being used to effect receptor design. The combination of biological overview and summary of current synthetic approaches provides a coverage that is both comprehensive and comprehensible. First, the authors detail the key design motifs that have been used to generate synthetic receptors and which are likely to provide the basis for further developments. They also highlight briefly some of the features that are present in naturally occurring anion recognition and transport systems and summarise the applications of anion recognition chemistry. Providing as it does a detailed review for practitioners in the field and a concise introduction to the topic for newcomers, Anion Receptor Chemistry reflects the current state of the art. Fully referenced and illustrated in colour, it is a welcome addition to the literature.
