[0106] Synthesis of Compound 10

[0107]

[0108] Under an argon or nitrogen atmosphere, 10 g of reactant (1), 12 g of reactant (2), 0.9 g of Tetrakis (triphenyl phosphine) palladium (0) were mixed with a 250 ml volumetric flask. )) was dissolved in 50 ml of dioxane, followed by adding a solution in which 11.2 g of sodium carbonate was dissolved in 20 ml of water, followed by heating and stirring for 24 hours.

[0109] After the reaction was completed, it was cooled to room temperature and the precipitated crystals were separated by filtration. It was recrystallized from toluene to synthesize 6.5 g (40%) of compound 10.

Abstract

The invention provides a novel compound and an organic electroluminescent device comprising the same. The present invention provides a novel compound represented by the following Formula 1 (as shown in the description) and an organic light emitting device including the above novel compound. In the above Formula 1, Ar is independently hydrogen, substituted or unsubstituted C<6> to C<30> Aryl, substituted or unsubstituted C<6>-C<30> heteroaryl, and at least one of the two is phenyl or pyridyl, and X is independently CR<1> or N, wherein R<1> is hydrogen, halogen, amino, nitrile Alkyl, nitro, substituted or unsubstituted C<1> to C<30> alkyl, substituted or unsubstituted C6 to C30 aryl, substituted or unsubstituted C2 to C30 heteroaryl, A and B, respectively substituted or unsubstituted C<6>-C<30> aryl, substituted or unsubstituted C<2>-C<30> heteroaryl).

Description

technical field [0001] The present invention relates to a novel compound and an organic light-emitting element comprising the novel compound. Background technique [0002] In recent years, self-luminous organic light-emitting elements that can be driven by low voltages are relatively low-voltage flat panel display elements, namely liquid crystal displays (LCDs), because of their excellent viewing angle and contrast performance, and do not require backlights. It is easy to achieve thin and light, low power consumption, wide color reproduction range and other characteristics, attracting attention as a next-generation display element. [0003] Materials used as organic layers in organic light emitting diodes can be roughly classified into light emitting layer materials, hole injection layer materials, hole transport layer materials, electron transport layer materials, electron injection layer materials, and the like according to their functions. In addition, the above-mentione...
