1. A polycyclic compound represented by Formula 1 or 2:

OG Complex Work Unit Chemistry
wherein X is B, P═O, P═S or A1, Y1 and Y2 are each independently NR1, O, S, CR2R3 or SiR4R5, Y3 is O or S, A1 to A3 are each independently selected from substituted or unsubstituted C5-C50 aromatic hydrocarbon rings, substituted or unsubstituted C2-C50 aromatic heterocyclic rings, substituted or unsubstituted C3-C30 aliphatic rings, and substituted or unsubstituted C3-C30 mixed aliphatic-aromatic rings, with the proviso that A2 essentially has a substituted or unsubstituted amine group as a substituent, and R and R1 to R5 are identical to or different from each other and are each independently selected from hydrogen, deuterium, substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C2-C30 alkenyl, substituted or unsubstituted C6-C50 aryl, substituted or unsubstituted C3-C30 cycloalkyl, substituted or unsubstituted C3-C30 heterocycloalkyl, substituted or unsubstituted C2-C50 heteroaryl, substituted or unsubstituted C1-C30 alkoxy, substituted or unsubstituted C6-C30 aryloxy, substituted or unsubstituted C1-C30 alkylthioxy, substituted or unsubstituted C5-C30 arylthioxy, substituted or unsubstituted amine, substituted or unsubstituted silyl, substituted or unsubstituted C3-C30 mixed aliphatic-aromatic cyclic groups, nitro, cyano, and halogen, with the proviso that the groups R are other than substituted or unsubstituted C1-C30 alkyl, each of R1 to R5 optionally forms an alicyclic or aromatic monocyclic or polycyclic ring with one or more of the rings A1 to A3, the groups R are optionally linked to each other to form an alicyclic or aromatic monocyclic or polycyclic ring, R2 and R3 together optionally form an alicyclic or aromatic monocyclic or polycyclic ring, and R4 and R5 together optionally form an alicyclic or aromatic monocyclic or polycyclic ring.
