1. A triazine ring-containing polymer comprising a structural unit represented by General Formula 1:
*-[A-B-]-*  General Formula 1
wherein, in General Formula 1,
A is represented by General Formula 2,
B is represented by General Formula 3, and
indicates a point linked to another structural unit or atom;

OG Complex Work Unit Chemistry
wherein, in General Formula 2,
L is a single bond or a linking group,
R1 is a group comprising an oxygen atom, a sulfur atom, a nitrogen atom, a selenium atom, or a combination thereof,
with the proviso that when R1 comprises a nitrogen atom, then R2 is represented by one of the following chemical formulae:

and
indicates a point linked to another structural unit or atom;
*-[—(CR3R4)m1—R2—(CR5R6)n1—]-*  General Formula 3
wherein, in General Formula 3,
R2 is a divalent aromatic hydrocarbon group, or an aromatic hydrocarbon linking group in which two or more aromatic hydrocarbon groups are linked to each other by an alkylene group, an oxygen atom, a sulfur atom, or a selenium atom,
R3 to R6 are each independently a hydrogen atom, an alkyl group, or an aromatic hydrocarbon group,
m1 and n1 are independently 0 or 1, wherein at least one of m1 and n1 of General Formula 3 is 1 when R1 is a group comprising a sulfur atom, and
indicates a point linked to another group or structural unit.
