METHOD FOR PRODUCING POLYMER COMPOUND

摘要

Disclosed is a method for producing a polymer compound containing a repeating unit represented by formula (4), wherein a compound represented by formula (1) is caused to react with a compound represented by formula (2) or a compound represented by formula (3). A polymer compound that has high absorbance of light having a long wavelength can be produced by this method. (In formula (1), R represents a hydrogen atom, a fluorine atom, an alkyl group that may be substituted by a fluorine atom, an alkoxy group that may be substituted by a fluorine atom or an optionally substituted aryl group; and Q represents a dihydroxyboryl group or a boric acid ester residue.) (In formula (4), a represents 0 or 1; R is as defined above; and T represents a hydrogen atom, a fluorine atom, an alkyl group that may be substituted by a fluorine atom, an alkoxy group that may be substituted by a fluorine atom or an optionally substituted aryl group.)
