Abstract

A polymer (A) includes a repeating structural unit represented by formula (1). R11 represents a divalent substituted or unsubstituted nitrogen-containing heteroaromatic ring; R12's independently represent a divalent substituted or unsubstituted aromatic hydrocarbon group; R13 represents a hydrocarbon group having 1 to 20 carbon atoms to which at least one group represented by formula (a1) is bonded in addition to two R12's; X1's independently represent —O—, —S—, or —N(R14)—; and R14 is a hydrogen atom, a monovalent hydrocarbon group having 1 to 20 carbon atoms, a monovalent halogenated hydrocarbon group having 1 to 20 carbon atoms, or a group in which the hydrocarbon group or the halogenated hydrocarbon group is partially substituted with an oxygen atom, a sulfur atom, or both. In formula (a1), * represents a linkage to the R13; ** represents a bond to another structural unit in the polymer (A).
