Embodiment 1

[0244] will be Thin film coated glass substrates with indium tin oxide (ITO) were cleaned with distilled water and ultrasonic waves. After cleaning with distilled water, ultrasonically clean and dry with solvents such as isopropanol, acetone, methanol, etc., and then transfer to a plasma cleaner, use oxygen plasma to clean the above-mentioned substrate for 5 minutes, and then use a thermal vacuum coating machine (thermalevaporator) , Fabricate the hole injection layer HT01 on the top of the ITO substrate NPB as a hole transport layer membrane. Then, as the above-mentioned light-emitting layer, compound 1: Ir(ppy) 3 10% is doped, making membrane. Then, as an electron transport layer, fabricated with ET01:Liq (1:1) After the film is fabricated LiF film, Aluminum (Al) The film was sealed in a glove box (Encapsulation), thereby producing a green organic light-emitting element.

Embodiment 2～ Embodiment 10

[0246] Green organic light-emitting devices were produced by using the same method as in Example 1, each using Compounds 2 to 10 as the main body of the light-emitting layer to form a film.

Embodiment 11

[0248] will be Thin film coated glass substrates with indium tin oxide (ITO) were cleaned with distilled water and ultrasonic waves. After cleaning with distilled water, ultrasonically clean and dry with solvents such as isopropanol, acetone, methanol, etc., and then transfer to a plasma cleaner, use oxygen plasma to clean the above-mentioned substrate for 5 minutes, and then use a thermal vacuum coating machine (thermalevaporator) , on the top of the ITO substrate, the hole injection layer HT01 is fabricated Compound 11 as a hole transport layer membrane. Then, as the above-mentioned light-emitting layer, it was doped with BH01:BD01 5% to produce membrane. Then, as an electron transport layer, with Alq 3 : Liq(1:1) manufacturing After the membrane, manufacture Liq film, Aluminum (Al) The film was sealed in a glove box (Encapsulation), thereby producing a green organic light-emitting element.

Abstract

The present invention relates to a novel compound and, particularly, to: a novel compound having excellent hole and electron transport properties, capable of simultaneously implementing high triplet energy and high Tg, and capable of allowing an organic light emitting device to have low driving voltage, low power consumption, high efficiency and long lifetime when applied to an organic light emitting device; and an organic light emitting device containing the same.

Description

technical field [0001] The present invention relates to a novel compound and an organic light-emitting element comprising the same, in particular to excellent hole and electron transport characteristics when applied to an organic light-emitting element, while being able to achieve high triplet energy and high Tg, and enabling it to have a low driving voltage, New compound with 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. [0003] Materials used as organic layers in organic light-emitting devices can be roug...
