Diarylethene Molecular Photoswitches Concepts and Functionalities

A comprehensive review to the synthesis, properties, and applications of diarylethene-based molecular photoswitches

Diarylethene Molecular Photoswitches: Concept and Functionalities provides the fundamental concepts of molecular photoswitches and includes information on how the bistable photoswitches of diarylethenes modulate the functions of materials and biological activities. Written by Masahiro Irie (the inventor of photochromic diarylethene compound), the book explores the reaction mechanism, photoswitching performance, photoswitchable crystals, and the myriad applications of diarylethenes based photoswitches.

This book offers academics, chemists, and engineers an essential resource for understanding the molecular photoswitches and provides a guide to the development of new photoresponsive materials. The author explores the applications based on diarylethene and its dirivatives to Field-Effect Transistors, Metal-Organic Frameworks including nanoparticles, super-resolution fluorescence microscopies, drug release, and self-healing materials. This important book:

* Offers a guide to diarylethene derivatives, the most widely studied compounds worldwide among the photochromic compounds
* Includes the basic concepts of molecular photoswitches
* Explores the myraid applications grounded in diarylethene and its derivatives
* Presents an authortative text from the inventor of the photochromic diarylethene compound

Written for materials scientists, organic, polymer, and physical chemists, and electronics engineers, Diarylethene Molecular Photoswitches offers an introduction to the topic and includes recent developments in the field.

Masahiro Irie is an emeritus professor of Kyushu University. He received his B.S. and M.S. from Kyoto University and his Ph.D. in radiation chemistry from Osaka University. In 1968 he joined the Faculty of Engineering, Hokkaido University, as a research associate and started his research in photochemistry. He was the faculty members of at Osaka University, Kyushu University and Rikkyo University. He has been conducting research on molecular photoswitch systems for more than 40 years. In the middle of the 1980s he discovered thermally irreversible and fatigue resistant photochromic diarylethenes. Prof. Irie has authored over 500 scientific publications and has received numerous scientific awards, including Porter Medal (European Photochemistry Association, The Inter-American Photochemistry Society and Asian and oseanian Photochemsitry association), Theodor-Foerster-Preis (GDCh and Deutsche Bunsen-Gesellschaft, Germany) and The Chemical Society of Japan Award.
