Abstract
A polymer comprising a polymer chain moiety and a copper complex moiety (1) is useful as a mechanoresponsive luminescent material. R1 and R2 are linking groups to the polymer chain moiety; R3 to R6 are H or substituent.

A polymer comprising a polymer chain moiety and a copper complex moiety represented by the following formula (1):
- wherein R1 and R2 each independently represent a linking group to the polymer chain moiety;
- and R3 to R6 each independently represent a hydrogen atom or a substituent, provided that R3 and R4, R4 and R5, and R5 and R6 each may be bonded to each other to form a cyclic structure, and at least one of the pyridine rings may be substituted.
A method for preparing a polymer comprising a polymer chain moiety and a copper complex moiety represented by the following formula (1):
- wherein R1 and R2 each independently represent a linking group to the polymer chain moiety;
- and R3 to R6 each independently represent a hydrogen atom or a substituent, provided that R3 and R4, R4 and R5, and R5 and R6 each may be bonded to each other to form a cyclic structure, and at least one of the pyridine rings may be substituted,
- wherein the method comprises:
- (1a) copolymerizing a monomer and a compound represented by the following formula (3a) to obtain a precursor polymer:
- wherein R21 and R22 each independently represent a polymerizable group, and at least one of the pyridine rings may be substituted;
- or
- (1b) reacting a polymer chain having a first functional group and a compound represented by the following formula (3b) to obtain a precursor polymer:
- wherein R23 and R24 each independently represent a group having a second functional group that reacts with the first functional group to form a bond, and at least one of the pyridine rings may be substituted;
- and then,
- (2) reacting the precursor polymer and a compound represented by the following formula (4):
- wherein X1 represents a halogen atom, a triflate group, or a pseudohalogen group;
- and R3 to R6 each independently represent a hydrogen atom or a substituent, provided that R3 and R4, R4 and R5, R5 and R6 each may be bonded to each other to form a cyclic structure.
