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, Y 1 and Y 2 each denote a substituent group that inhibits aggregation of the mechanochromic luminescent material represented by formula (1), and Y 1 and Y 2 may be same as or different from each other. Z 1 and Z 2 each denote a polymerizable group, and may be same as or different from each other.) [Chemical formula 2] (In the formula, Y 1 and Y 2 each denote a substituent group that inhibits aggregation of the mechanochromic luminescent material represented by formula (2), and Y 1 and Y 2 may be same as or different from each other. Z 1 and Z 2 each denote a polymerizable group, and may be same as or different from each other.)
