Aggregation-Induced Emission (AIE) is a novel photophysical phenomenon which offers a new platform for researchers to look into the light-emitting processes from luminogen aggregates, from which useful information on structure–property relationships may be collected and mechanistic insights may be gained. The discovery of the AIE effect opens a new avenue for the development of new luminogen materials in the aggregate or solid state. By enabling light emission in the practically useful solid state, AIE has the potential to expand significantly the technological applications of luminescent materials. Aggregation-Induced Emission: Fundamentals is the first book to explore the fundamental issues of AIE, including the design, synthesis, and photophysical behavior of AIE-active molecules and polymers. The control of the morphological structures of the aggregates of AIE-active materials, and the experimental investigation and theoretical understanding of the AIE mechanism, are also covered in this volume. Topics covered include: AIE in group 14 metalloles AIE in organic ion pairs Red light-emitting AIE materials Supramolecular structure and AIE AIE-active polymers Enhanced emission by restriction of molecular rotation Crystallization-induced emission enhancement Theoretical understanding of AIE phenomena This book is essential reading for scientists and engineers who are designing optoelectronic materials and biomedical sensors, and will also be of interest to academic researchers in materials science and physical and synthetic organic chemistry, as well as physicists and biological chemists.

Click chemistry describes organic reactions which are highly efficient, regioselective and allow for mild reaction conditions. The archetypal click reaction of Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) is used in many diverse areas and has been extensively developed for polymer synthesis, leading to the term of click polymerization. This technique enables the preparation of functional polymers with linear and topological structures that have the potential to be used in optoelectronics and biological fields. Edited by world renowned experts, Click Polymerization is the first book to comprehensively summarize this approach to polymer synthesis consolidating all the different reaction types in one resource. From the basic knowledge through to the latest developments in synthesis, chapters include transition-metal catalysed and metal-free azide-alkyne click polymerizations as well as thiol-ene, thiol-yne and thiol-epoxy click polymerizations. The book provides an authoritative guide to click polymerization techniques for graduate students and researchers interested in polymer chemistry and materials science.

Polymeric materials form the basis of daily life. Despite the great contribution of traditional methodologies such as anionic and radical polymerizations in preparing various functional polymers, the increasing demand for polymers with new structures and functions has inspired the development of new synthetic techniques. Many new polymerizations including click polymerization, controlled/living radical polymerization, multicomponent polymerization have been well developed. Focusing on breakthroughs and recent progress, Synthetic Polymer Chemistry provides efficient tools for the synthesis of linear and topological polymers. Chapters cover topics including fabrication of supramolecular polymers, organocatalytic synthesis and olefin co(polymerization). This title will be a valuable reference for those working in polymer chemistry, as well as students and researchers interested in opto-electronic, biological and materials sciences.
