Polycyclic aromatic derivative compound and organic light-emitting device using same

A polycyclic aromatic derivative represented by Formula A:

• wherein Q1 to Q5 are identical to or different from each other and are each independently a substituted or unsubstituted C6-C50 aromatic hydrocarbon ring or a substituted or unsubstituted C2-C50 aromatic heterocyclic ring, each X is independently selected from B, P, P═O, and P═S, each Y is independently selected from N—R1, CR2R3, O, S, Se, and SiR4R5, 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 C6-C50 aryl, substituted or unsubstituted C3-C30 cycloalkyl, 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 C1-C30 alkylamine, substituted or unsubstituted C5-C30 arylamine, substituted or unsubstituted C1-C30 alkylsilyl, substituted or unsubstituted C5-C30 arylsilyl, nitro, cyano, and halogen, with the proviso that each of R1 to R5 is optionally bonded to one of the rings Q1 and Q5 to form an alicyclic or aromatic monocyclic or polycyclic ring, R2 and R5 are optionally linked to each other to form an alicyclic or aromatic monocyclic or polycyclic ring, and R4 and R5 are optionally linked to each other to form an alicyclic or aromatic monocyclic or polycyclic ring, and with the proviso that (i) either or both of Q1 and Q5 are optionally selected from structures represented by Structural Formulae B-1 to B-3:
• wherein each Y is independently selected from N—R1, CR2R3, O, S, Se, and SiR4R5, R1 to R5 are as defined in Formula A, Q6 is a substituted or unsubstituted C6-C50 aromatic hydrocarbon ring or a substituted or unsubstituted C2-C50 aromatic heterocyclic ring, each R is independently selected from hydrogen, deuterium, substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C6-C50 aryl, substituted or unsubstituted C3-C30 cycloalkyl, 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 C1-C30 alkylamine, substituted or unsubstituted C5-C30 arylamine, substituted or unsubstituted C1-C30 alkylsilyl, substituted or unsubstituted C5-C30 arylsilyl, nitro, cyano, and halogen, with the proviso that the groups R are optionally bonded to each other or are each independently optionally bonded to one of the rings Q1 and Q5 to form an alicyclic or aromatic monocyclic or polycyclic ring, and each * represents a position at which the corresponding ring Q1 or Q5 is bonded to the adjacent X and Y in Formula A, (ii) Q3 is selected from structures represented by Structural Formulae B-4 to B-6:
