During the past 100 years, a large number of new materials have been developed, which provide us with various tools, wares, clothes, etc. with good properties but low weight and low cost. Recently, smart soft materials that can respond to an external stimulus (such as an electric field, magnetic field, sound, light, temperature, pH, and so on) as well as functional soft materials that are electronically, magnetically, or thermally conductive have attracted considerable attention. They have application potentials in various fields. To some extent, they are the way to fulfill most of the "black technology" described in the world of science fiction. This book introduces several smart soft materials and functional soft materials, which are of interest to scholars in related fields.

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.

In 1978, Fred Hoyle proposed that interstellar comets carrying several viruses landed on Earth as part of the panspermia hypotheses. With respect to life, the origin of homochirality on Earth has been the greatest mystery because life cannot exist without molecular asymmetry. Many scientists have proposed several possible hypotheses to answer this long-standing L-D question. Previously, Martin Gardner raised the question about mirror symmetry and broken mirror symmetry in terms of the homochirality question in his monographs (1964 and 1990). Possible scenarios for the L-D issue can be categorized into (i) Earth and exoterrestrial origins, (ii) by-chance and necessity mechanisms, and (iii) mirror-symmetrical and non-mirror-symmetrical forces as physical and chemical origins. These scenarios should involve further great amplification mechanisms, enabling a pure L- or D-world.

This book compiles the accomplishments of the recent research project on photochemistry “Photosynergetics”, supported by the Ministry of Education, Culture, Sports, Science and Technology of Japan, aiming to develop and elucidate new methods and molecules leading to advanced utilization of photo-energies. Topics include photochemical responses induced by multiple excitation, multiphoton absorption, strong modulation of electronic states, developments of new photofunctional molecules, mesoscopic actuations induced by photoexcitation, and novel photoresponses in molecules and molecular assemblies. The authors stress that these approaches based on the synergetic interaction among many photons and many molecules enable the expansion of the accessibility to specific electronic states. As well, they explain how the development of reaction sequences and molecules/molecular assemblies ensure “additivity” and “integration” without loss of the photon energy, leading to new photoresponsive assemblies in meso- and macroscopic scales.

Smart materials have been produced by conceiving of the idea of materials/systems having a fourth dimension. To match advances in instrumentation, efforts are being made to develop materials, resulting in smart materials with enhanced performance. In nature, the action of stimuli-responsive materials is reversible; this idea has attracted interest for its potential research and industrial applications. The challenge remains how to couple these applications with environmental consciousness. This book presents the basics of smart polymers and describes their current and future applications. This book is different from other books on the subject in that it explores polymer materials’ smart behavior in more depth, covering vibration damping, thermal and electrochemical energy, sensing at trace level, biotechnology, and so on. The 14 chapters in this book cover diverse areas, including: • Photoresponsive polymers that can be manipulated using a specific frequency of light • Designing polymers for vibration damping • Smart manipulations of hydrophobic and super-hydrophobic polymers • Biopolymers, including hydrogels for smart application, drug delivery, and other uses • Smart paints • Self-healing and shape memory polymers • Holography for data storage • Phase change polymers and solid polymer electrolytes for thermal and electrochemical energy • Molecular imprinting polymers for sub-ppm sensing and removal of unwanted materials • Smart textiles, and the concept of advanced textiles This book will be of particular interest to researchers, postgraduates, and industry experts. It offers an extensive introduction to the basics of smart polymers and their possible applications.
