A is a spacer, and is a substituted or unsubstituted C1-C12 alkylene group, a substituted or unsubstituted C2-C12 alkenylene group, a substituted or unsubstituted C2-C12 alkynylene group, a substituted or unsubstituted C6-C12 arylene group, or a substituted or unsubstituted C4-C12 heteroarylene group; and
E1 and E2 are the same or different epoxy-containing group;, wherein, in Formula 2,
R1 to R12 are each independently a hydrogen atom, a halogen atom, C1-C30 alkyl group, C2-C30 alkenyl group, C2-C30 alkynyl group, C1-C30 alkoxy group, C2-C30 alkoxyalkyl group, C1-C30 heteroalkyl group, C6-C30 aryl group, C7-C30 arylalkyl group, C2-C30 heteroaryl group, C3-C30 heteroarylalkyl group, C2-C30 heteroaryloxy group, C3-C30 heteroaryloxyalkyl group, C6-C30 heteroarylalkyloxy group, a hydroxy group, a nitro group, a cyano group, an amino group, an amidino group, a hydrazine group, a hydrazone group, a carboxyl group or a salt thereof, a sulfonyl group, a sulfamoyl group, a sulfonic acid or a salt thereof, or a phosphoric acid or a salt thereof,
L4 of Formula 2-12 to 2-15 is —O—, —C(═O)O—, —O—C(═O)O—, —(CH2)2—C(═O)—, —CH═CH—C(═O)—, —S(═O)—, —CH═N—, —NHC(═O)O—, —C(═O)NH—, —OC(═O)NHS(═O)O—, or —CH2(C6H4)C(═O)—, and
X is N, P, or As, Y is O, S, or Se, and
n is an integer of 1 to 10; and
wherein
a segment M1p-L1x-M2q-L2y-M3r of Formula 1 has at least one group structure represented by Formula 3:, wherein, in Formula 3, n is an integer of 1 to 10, or
at least one group structure represented by Formula 4, where n of Formula 4 is an integer of 3 to 10;,
