Example Embodiment

[0223] Example 1

[0224] Will be The glass substrate coated with indium tin oxide (ITO) of the thick film is ultrasonically cleaned with distilled water. After cleaning with distilled water, ultrasonic cleaning and drying with solvents such as isopropanol, acetone, methanol, etc., and then transfer to a plasma cleaning machine, use oxygen plasma to clean the above-mentioned substrate for 5 minutes, then use a thermal evaporator , On the top of the ITO substrate, a hole injection layer HT01 is fabricated Film, compound as a hole transport layer 的膜。 The film. Then, as the light-emitting layer, the host BH01 is doped with 3% BD01 to produce 的膜。 The film. Then, as the electron transport layer, it is made with ET01:Liq (1:1) After the film, manufacture LiF Film, aluminum (Al) The device was sealed in a glove box (Encapsulation) to produce an organic light-emitting device.

Example

[0225] Examples 2 to 20

[0226] By the same method as in Example 1, an organic light-emitting element in which a hole transport layer was manufactured using Compounds 2 to 20, respectively, was produced.

Example Embodiment

[0227] Example 21

[0228] By the same method as in Example 1, an organic light-emitting element in which a hole transport layer was manufactured using a composition obtained by mixing compound 4 and compound 5 at a 50:50 (weight ratio) was produced.

Abstract

The present invention relates to a novel compound and, especially, to a novel compound which, when applied to an organic light emitting device, has excellent hole injection and hole transport properties and simultaneously has an excellent electron blocking property, can implement high triplet energy and high Tg, and enables the organic light emitting device to have low driving voltage, low power consumption, high efficiency, and long lifetime.

Description

technical field [0001] The present invention relates to a novel compound and an organic light-emitting element comprising the same, especially relates to excellent hole injection and hole transport characteristics when applied to an organic light-emitting element, and excellent electron blocking characteristics at the same time, capable of achieving high triplet energy and high Tg, and enabling It is a new compound with low driving voltage, low power consumption, high efficiency and long life. Background technique [0002] In recent years, self-illuminating organic light-emitting elements that can be driven at low voltages have superior viewing angles and contrast ratios compared to liquid crystal displays (LCDs) that are the mainstream of flat panel display elements. Lightweight and thin, it is also advantageous in terms of power consumption, and the color reproduction range is wide, so it is attracting attention as a next-generation display element.
