CHAPTER 1:Mechanofluorochromism: An Overview

An overview of mechanoflurochromism is provided. As a new class of smart materials, mechanofluorochromic materials are different from the traditional mechanochromic materials. Under mechanical force stimulus, both the sample color and the emission color of the mechanofluorochromic materials are changed. They are widely applicable for fluorescence switches, mechanosensors, indicators of mechanohistory, security papers, optoelectronic devices and data storage in various fields. To date, there are still many experimental and theoretical challenges to be overcome for a better comprehension of the molecular behaviors in the solid state under mechanical stimuli.
