Embodiment 1 to 20

[0214] Examples 1 to 20: Synthesis of Compounds

[0215] Using the above intermediates IM1 to IM11, the target compounds 1 to 20 were synthesized as follows.

Embodiment 1

[0216] Embodiment 1: the synthesis of compound 1

[0217]

[0218] In a round bottom flask, 3.0 g of IM1, 2.17 g of di([1,1'-biphenyl]-4-yl)amine (di([1,1'-biphenyl]-4-yl)amine) , 0.9g of t-BuONa, 0.2g of Pd 2 (dba) 3 , 0.3ml of (t-Bu) 3 After P was dissolved in 80 ml of toluene, stirring was performed under reflux. The reaction was confirmed by thin layer chromatography, and the reaction was terminated after adding water. The organic layer was extracted with dichloromethane, filtered under reduced pressure, followed by column purification and recrystallization to obtain 3.0 g of Compound 1 (yield 67%).

[0219] m / z: 729.27 (100.0%), 730.27 (58.9%), 731.27 (17.4%), 732.28 (3.2%)

Embodiment 2

[0220] Embodiment 2: the synthesis of compound 2

[0221]

[0222] Utilize N-([1,1'-biphenyl]-4-yl)naphthalen-1-amine (N-([1,1'-biphenyl]-4-yl)naphthalen-1-amine) to replace di( [1,1'-biphenyl]-4-yl)amine, compound 2 was synthesized in the same manner as compound 1 (yield 63%).

[0223] m / z: 703.25 (100.0%), 704.25 (56.6%), 705.26 (16.2%), 706.26 (3.1%)

Description

technical field [0001] The present invention relates to novel compounds and organic light-emitting devices comprising them. Background technique [0002] In organic light emitting diodes, materials used as organic layers can be roughly classified into light emitting materials, hole injection materials, hole transport materials, electron transport materials, electron injection materials, etc. according to functions. Moreover, the above-mentioned luminescent materials can be classified into high molecular weight and low molecular weight according to the molecular weight, and can be classified into fluorescent materials derived from the singlet excited state of electrons and phosphorescent materials derived from the triplet excited state of electrons according to the light emitting mechanism. Luminescent colors are classified into blue, green, red luminescent materials and yellow and orange luminescent materials required to reflect better natural colors. Also, in order to incr...
