Abstract

A thiophene-containing compound polymer represented by Y represents a bivalent hydrocarbon group; R 5 represents a hydrogen atom; Z represents a bivalent hydrocarbon group; m represents 1; p represents an integer of 5 to 5,000; B and B′ each represent OCH 2 CH 2 OH, and A represents a group represented by the following formula (X-III): Ar 1 is a substituted or unsubstituted monovalent aromatic group; R 1 to R 3 each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group; and n representing an integer of 1 to 5.
