preparation example 1

[0178] Preparation Example 1: Synthesis of IM1

[0179] The synthesis method of the following IM1 is as follows.

[0180]

[0181] In a round bottom flask, dissolve 30.0 g of (4-(naphthalen-1-yl)phenyl)boronic acid and 26.3 g of 1-bromo-4-iodobenzene in 600 ml of 1,4-bis Alkanes, and put in 160ml of K 2 CO 3 (2M) and 3.7g of Pd(PPh 3 ) 4 Thereafter, reflux stirring was performed. The reaction was confirmed by thin layer chromatography (T LC), and after adding water, the reaction was terminated. The organic layer was extracted with methylcellulose (MC), filtered under reduced pressure, and then column purified to obtain 24.0 g of intermediate I M1 (63% yield).

[0189]

[0190] In a round bottom flask, add 3.0 g of IM1, bis([1,1':4',1"-terphenyl]-4-yl)amine (di([1,1':4',1"-terphenyl ]-4-yl)amine)) 4.4g, t-BuONa 1.2g, Pd 2 (d ba) 3 0.3g, (t-Bu) 3 0.4 ml of P was dissolved in 120 ml of toluene, and stirred under reflux. The reaction was confirmed by thin layer chromatography, and after adding water, the reaction was terminated. The organic layer was extracted with methylcellulose, filtered under reduced pressure, and then recrystallized to obtain 3.7 g of Compound 20 (59% yield).

Abstract

The present invention relates to a compound for a capping layer and an organic light-emitting device comprising the same, the compound for a capping layer according to one embodiment of the present invention being suitable for an organic light-emitting device and being capable of improving the external light-emitting efficiency, chromaticity coordinates, and lifespan of the organic light-emittingdevice.

Description

technical field [0001] The present invention relates to an organic compound for a covering layer and an organic light-emitting device comprising the same. Background technique [0002] In an organic light emitting device, materials used as an organic layer can be roughly classified into light emitting materials, hole injection materials, hole transport materials, electron transport materials, electron injection materials, etc. according to functions. Also, the above-mentioned light emitting materials can be classified into fluorescent materials derived from a singlet excited state of electrons and phosphorescent materials derived from a triplet excited state of electrons according to the light emitting mechanism. Furthermore, they can be classified into blue, green, and red light-emitting materials according to their light-emitting colors. [0003] A general organic light-emitting device may have a structure in which an anode is formed on a substrate, and a hole transport l...
