Claims23
A photoresponsive polymer that is fluidized by light irradiation and reversibly non-fluidized and contains a structural unit represented by a general formula (1) shown below:
- wherein r1 is a hydrogen atom or a methyl group, and
- A is a propenimine structure-containing group represented by a general formula (2-a), (2-b), or (2-c) shown below:
- wherein Z1 and Z2 are each independently N or CX, and Z1≠Z2,
- B1 is each independently a substituted or unsubstituted divalent aromatic hydrocarbon group or a substituted or unsubstituted divalent aromatic heterocyclic group,
- B2 is each independently a substituted or unsubstituted monovalent aromatic hydrocarbon group or a substituted or unsubstituted monovalent aromatic heterocyclic group,
- X, r2, and r3 are each independently a hydrogen atom or an alkyl group having 1 to 2 carbon atoms, and
- r4 is each independently an alkylene group having 1 to 18 carbon atoms.
