[0306]

[0307]

[0308]

[0309]

[0310] Using material 1 as the hole transport layer, the compound of formula 47 as the hole injection layer, the compound of formula 48 as the main body of the light-emitting layer, and the compound of formula 49 as the dopant of the light-emitting layer to prepare an organic EL device with the following structure: ITO / style / Material / formula 48:formula

[0311] 15Ω / cm 2 ( ) ITO glass substrates were cut into pieces of size 50mmx50mmx0.7mm, followed by ultrasonic cleaning in acetone, isopropanol and pure water (15 minutes each), followed by UV / ozone cleaning (30 minutes) to form the anode. The compound of formula 47 (hole injection layer) and material 1 (hole transport layer) were vacuum deposited on the anode. A mixture of the compound of Formula 48 and the compound of Formula 49 (weight ratio 100:5) was vacuum deposited to form a light emitting layer. Then, the Alq3 compound was vacuum-depo...

[0314]

[0315] Using material 3 as the main body of the light-emitting layer and the compound of formula 50 as the dopant of the light-emitting layer to prepare an organic EL device with the following structure: ITO / formula / α-NPD( ) / Material 3: formula

[0316] 15Ω / cm 2 ( ) ITO glass substrates were cut into pieces of size 50mmx50mmx0.7mm, followed by ultrasonic cleaning in acetone, isopropanol and pure water (15 minutes each), followed by UV / ozone cleaning (30 minutes) to form the anode. The compound of formula 47 (hole injection layer) and α-NPD (hole transport layer) were vacuum deposited onto the anode. A mixture (weight ratio 100:10) of Material 3 and RD15 (Formula 50) was vacuum deposited to form a light emitting layer. Then, the Alq3 compound was vacuum-deposited on the light-emitting layer to thickness to form an electron transport layer. The LiF( electron injection layer) and Al ( Cathode) is sequentially vacuum-deposited on the e...

Embodiment 3

[0318] An organic EL device with the following structure was prepared in the same manner as in Example 1, except that α-NPD was used as the hole transport layer and material 4 was used as the dopant of the light emitting layer: ITO / Formula / α-NPD Equation 48: Material This organic EL device exhibits 4600cd / m at 8V 2 Blue light emission and efficiency of 5.4cd / A.

Abstract

Provided are a cyclopentaphenanthrene-based compound and an organic EL device using the same. The cyclopentaphenanthrene-based compound is easy to prepare and excellent in solubility, color purity, and color stability. The cyclopentaphenanthrene-based compound is useful as a material for forming an organic layer, in particular, a light-emitting layer in an organic EL device, and as an organic dyeor an electronic material such as a nonlinear optical material.

Description

technical field [0001] The present invention relates to a cyclopentaphenanthrene-based compound and an organic electroluminescent device using the compound. More particularly, the present invention relates to a cyclopentaphenanthrene-based compound and an organic electroluminescent device including an organic layer made of the cyclopentaphenanthrene-based compound. Background technique [0002] An organic electroluminescent (EL) device is an active light-emitting display device that passes electrons and The recombination of holes produces light. The organic EL device has advantages such as light weight, simple constituent elements, easy manufacturing process, excellent image quality, and wide viewing angle. In addition, the organic EL device can perfectly produce dynamic images, achieve high color purity, and have electrical characteristics suitable for portable electronic devices due to low power consumption and low driving voltage. [0003] Eastman Kodak Co. developed a...
