Document Type and Number:
Japanese Patent JP7151468
Kind Code:
B2
Abstract:
To provide a fluorescent labeling agent excellent in fluorescence intensity and light fastness in a wavelength region of 900 nm or more.SOLUTION: The fluorescent labeling agent comprises a polymer [A]. The polymer [A] comprises a main chain structure having a divalent structure of 1H,2H,4H,5H-pyrrolo[3,4-c]pyrrol-1,4-dione and a divalent structure that independently has three of a substituted or unsubstituted aromatic hydrocarbon group or a substituted or unsubstituted aromatic heterocyclic group, in which two nitrogen atoms on a pyrrolo[3,4-c]pyrrole ring each independently have a monovalent substituted linear aliphatic hydrocarbon group, substituted or unsubstituted branched aliphatic hydrocarbon group, substituted or unsubstituted cyclic aliphatic hydrocarbon group, substituted or unsubstituted aromatic hydrocarbon group, substituted or unsubstituted aliphatic heterocyclic group, substituted or unsubstituted aromatic heterocyclic group, substituted or unsubstituted alkoxycarbonyl group, or substituted or unsubstituted aryloxy carbonyl group.SELECTED DRAWING: None
