Abstract

Mechanochromic fluorescent (or mechanofluorochromic) materials change their emission colours (spectra) when an appropriate external mechanical force stimulus is applied. This is an important group of materials with a huge range of applications, including use in sensors, memory chips, security inks, and light devices.

Mechanochromic Fluorescent Materials introduces the reader to the concept of mechanofluorochromism and the variety of applications of this group of materials. Prominent international figures in mechanofluorochromism consider the innovative research in this field over the last ten years. Chapters provide in depth coverage of most reported mechanofluorochromic systems, including organic and organic-inorganic complexes; polymer and polymer composites; and aggregation-induced emission.

This book is aimed to inform all students and researchers with an interest in mechanofluorochromism, and to help researchers identify and synthesize more of these materials, and develop the study and application of mechanofluorochromic materials.

Jiarui Xu graduated from Sun Yat-sen University in 1982 and received his Ph. D. from City University of New York in 1987. He conducted his postdoctoral work at North Carolina State University during 1987-89 and returned to SYSU in 1989. He was promoted to Professor in 1992. He received the National Science Fund for Distinguished Young Scholars from the National Natural Science Foundation of China in 1996. His research interests are polymer crystallization mechanism and crystalline structures, polymeric liquid crystals, polymer modification, mutilcomponent polymers, and new compounds with unique properties.

Zhenguo Chi received his B. S. degree in Chemistry (1991) from Hangzhou University (China) and his M. S. in chemistry and physics of polymer (1994) from Changchun Institute of Applied Chemistry, the Chinese Science Academy. He obtained a Ph. D. in 2003 from Sun Yat-sen University (China). In 2003-2006, he carried out his postdoctoral work in Fudan University (China) and Korea University (South Korea). He is currently an associate professor of physics and chemistry of materials at SYSU. His research is mainly on the development of organic and polymeric photoelectric materials.
