Embodiment 1

[0236] ultrasonication of distilled water A glass substrate coated with indium tin oxide (ITO) as a thin film was washed. When the distilled water washing is finished, use isopropanol, acetone, methanol and other solvents to perform ultrasonic cleaning, and after drying, transfer to a plasma cleaning machine, and then use oxygen plasma to clean the above-mentioned substrate for 5 minutes. The upper part uses a thermal vacuum depositor (thermal evaporator) as a hole injection layer to HI01 for film production, the The HATCN film is used as a hole transport layer to The HT01 film is used as a luminous supplementary layer to After compound 1 is film-formed, as the above-mentioned light-emitting layer doped with 9% GH01:GD01, to Make a film. Next, as the electron transport layer will After the ET01:Liq (1:1) was used to make the film, the of LiF, Aluminum (Al) film was formed, and the device was sealed (Encapsulation) in a glove box, thereby preparing an organic l...

Embodiment 2 to Embodiment 13

[0238] Compound 2 to Compound 13 were used instead of Compound 1 in the same manner as in Example 1, thereby preparing an organic light-emitting device.

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...
