This book explores functional polymers containing aromatic azo chromophores in side-chain, main-chain and other parts of their structures, known as azo polymers and which share common photoresponsive properties. It focuses on the molecular architecture of azo polymers, the synthetic methods and their most important functions, such as photoinduced birefringence and dichroism, surface-relief-grating (SRG) formation, and light-driven deformation of liquid crystal elastomers. It combines a general survey of the subject and in-depth discussions of each topic, including numerous illustrations, figures, and photographs. Offering a balance between an introduction to the core concepts and a snapshot of hot and emerging topics, it is of interest to graduate students and researchers working in this and related fields. Xiaogong Wang is a Professor at the Department of Chemical Engineering, Tsinghua University, China.

Chemical reactions which can, on demand, be switched on and off are valuable for industrial applications. In order to make the best use ofthese reactions, it is essential to have them readily available for a research chemist. The chemical literature, in general, has not yet identified or grouped such reactions. However, their existence is relatively abundant. This book is meant as a survey ofthose reactions which have potential utility in industrially useful processes. These reactions are grouped under the title ofchemical release reactions which can be triggered by heat, light, electric current, etc., to release a specific compound from, or change in the physical or chemical properties of, a unimolecular reactant. The book is divided into chapters covering ways to trigger the release of certain chemicals. Each chapter is further divided into sections, each beginning with a brief introduction ofanalogies ofthe discussed reactions and of how they were used in reported industrial processes. This survey is not meant to be absolute or exhaustive but rather to be directive, to be as complete as possible, and to provide food for further thought.

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.

This book presents a systematic study of the synthesis of optically active polymers, discussing in detail the syntheses of three different types of optically active polymers from helical polymers, dendronized polymers and other types of polymeric compounds. It also explains the syntheses of optically active azoaromatic and carbazole-containing azoaromatic polymers and copolymers; optically active benzodithiophene; and optically active porphyrin derivatives. The final chapter discusses different properties of optically active polymers such as nonlinear optical properties, chiroptical properties, vapochromic behaviour, absorption and emission properties, fabrication and photochromic properties. The intrinsic details of various properties of optically active polymers will offer a valuable resource for researchers and industry personnel actively engaged in application-oriented investigations.
