Abstract:
Provided is a compound having higher fluorescence quantum yield and higher optical stability than a conventional FLAP and a polymer compound containing the compound. The object is achieved by providing a compound represented by the following general Formula (1).
Symbols in general Formula (1) are defined as follows: A denotes a seven-membered ring or eight-membered ring structure, Y 1 and Y 2 each denote, independently, a halogen atom or the like, a1 denotes the number of the substituent groups Y 1 , and a2 denotes the number of the substituent groups Y 2 , Y 3 denotes a halogen atom or the like, b denotes the number of the substituent groups Y 3 , m and n each denote, independently, an integer greater than or equal to 0 and less than or equal to 3, when m is an integer greater than or equal to 1 and less than or equal to 3, Y 1 may be substituted with a structure portion defined by m, and similarly, when n is an integer greater than or equal to 1 and less than or equal to 3, Y 2 may be substituted with a structure portion defined by n, and B 1 and B 2 each denote, independently, any of the structures represented by the following general Formulas (2-1) to (2-3).
Symbols in general Formulas (2-1) to (2-3) are defined as follows: C 1 denotes a structure containing a cyclic hydrocarbon compound, C 2 and C 3 each denote a structure containing a cyclic hydrocarbon compound, D 1 , D 2 , and D 3 each denote a substructure that inhibits aggregation, E 1 , E 2 , and E 3 each denote a polymerizable substructure, Z 1 each denote, independently, a hydrogen atom or the like, c denotes the number of substituent groups Z 1 , and Z 2 and Z 3 each denote, independently a hydrogen atom or the like, and Z 2 and Z 3 may each form a ring with C 2 , independently.
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, 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.)
