  • Mechanochromic luminescent material, mechanochromic resin obtained by crosslinking mechanochromic luminescent material, method for producing mechanochromic luminescent material, and method for producing mechanochromic
    Patent number: 10442886
    Abstract: Provided is a mechanochromic resin by which a stress applied to a material can be visualized in real time, and a mechanochromic luminescent material that is used in the synthesis of the mechanochromic resin. Stress can be visualized in real time by means of a mechanochromic luminescent material represented by formula (1) or formula (2) and a mechanochromic resin obtained by crosslinking the mechanochromic luminescent material. [Chemical formula 1] (In the formula, Y1 and Y2 each denote a substituent group that inhibits aggregation of the mechanochromic luminescent material represented by formula (1), and Y1 and Y2 may be same as or different from each other. Z1 and Z2 each denote a polymerizable group, and may be same as or different from each other.) [Chemical formula 2] (In the formula, Y1 and Y2 each denote a substituent group that inhibits aggregation of the mechanochromic luminescent material represented by formula (2), and Y1 and Y2 may be same as or different from each other.
