Definitions
- the present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same.
- An electroluminescent device is a self-light-emitting display device which has advantages in that it provides a wider viewing angle, a greater contrast ratio, and a faster response time.
- the first organic EL device was developed by Eastman Kodak in 1987, by using small aromatic diamine molecules and aluminum complexes as materials for forming a light-emitting layer [Appl. Phys. Lett. 51, 913, 1987].
- An organic EL device changes electric energy into light by applying electricity to an organic light-emitting material, and commonly comprises an anode, a cathode, and an organic layer formed between the two electrodes.
- the organic layer of the OLED may comprise a hole injection layer, a hole transport layer, a hole auxiliary layer, a light-emitting auxiliary layer, an electron blocking layer, a light-emitting layer (containing host and dopant materials), an electron buffer layer, a hole blocking layer, an electron transport layer, an electron injection layer, etc., if necessary.
- the materials used in the organic layer can be classified into a hole injection material, a hole transport material, a hole auxiliary material, a light-emitting auxiliary material, an electron blocking material, a light-emitting material, an electron buffer material, a hole blocking material, an electron transport material, an electron injection material, etc., depending on functions.
- a hole injection material a hole transport material, a hole auxiliary material, a light-emitting auxiliary material, an electron blocking material, a light-emitting material, an electron buffer material, a hole blocking material, an electron transport material, an electron injection material, etc.
- holes from an anode and electrons from a cathode are injected into a light-emitting layer by the application of electric voltage, and an exciton having high energy is produced by the recombination of the holes and electrons.
- the organic light-emitting compound moves into an excited state by the energy and emits light from energy when the organic light-emitting compound returns to the ground state from the excited state
- the most important factor determining luminous efficiency in an organic EL device is light-emitting materials.
- the light-emitting materials are required to have the following features: high quantum efficiency, high movement degree of an electron and a hole, and uniformality and stability of the formed light-emitting material layer.
- the light-emitting material is classified into blue, green, and red light-emitting materials according to the light-emitting color, and further includes yellow or orange light-emitting materials. Furthermore, the light-emitting material is classified into a host material and a dopant material in a functional aspect. Recently, an urgent task is the development of an organic EL device having high efficiency and long lifespan.
- a host material should have high purity and a suitable molecular weight in order to be deposited under vacuum. Furthermore, a host material is required to have high glass transition temperature and pyrolysis temperature to achieve thermal stability, high electrochemical stability to achieve a long lifespan, easy formability of an amorphous thin film, good adhesion with adjacent layers, and no movement between layers.
- a material having an excellent thermal stability and capable of improving the performance of an organic electroluminescent device, such as driving voltage, luminescent efficiency, and lifespan properties, in a hole transport layer, a buffer layer, an electron transport layer, and the like, is required to be developed.
- the objective of the present disclosure is to provide an organic electroluminescent compound effective for producing an organic electroluminescent device having excellent thermal stability, low driving voltage, high luminous efficiency, and/or improved lifespan properties.
- a compound having a low Tg may reduce the charge mobility in a thin film and degrade the performance of the OLED device.
- the present inventors have developed a novel organic electroluminescent compound having a planar main core, which can assist pi-pi stacking in a vacuum deposition layer to lead to rapid charge mobility, and having a high glass transition temperature (Tg) in spite of its relatively low molecular weight, which can provide excellent morphological stability.

Abstract
The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. By comprising the organic electroluminescent compound of the present disclosure, it is possible to provide an organic electroluminescent device having excellent thermal stability, low driving voltage, high luminous efficiency, and/or improved lifespan properties.
Description
The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same.
An electroluminescent device (EL device) is a self-light-emitting display device which has advantages in that it provides a wider viewing angle, a greater contrast ratio, and a faster response time. The first organic EL device was developed by Eastman Kodak in 1987, by using small aromatic diamine molecules and aluminum complexes as materials for forming a light-emitting layer [Appl. Phys. Lett. 51, 913, 1987].
An organic EL device (OLED) changes electric energy into light by applying electricity to an organic light-emitting material, and commonly comprises an anode, a cathode, and an organic layer formed between the two electrodes. The organic layer of the OLED may comprise a hole injection layer, a hole transport layer, a hole auxiliary layer, a light-emitting auxiliary layer, an electron blocking layer, a light-emitting layer (containing host and dopant materials), an electron buffer layer, a hole blocking layer, an electron transport layer, an electron injection layer, etc., if necessary. The materials used in the organic layer can be classified into a hole injection material, a hole transport material, a hole auxiliary material, a light-emitting auxiliary material, an electron blocking material, a light-emitting material, an electron buffer material, a hole blocking material, an electron transport material, an electron injection material, etc., depending on functions. In the OLED, holes from an anode and electrons from a cathode are injected into a light-emitting layer by the application of electric voltage, and an exciton having high energy is produced by the recombination of the holes and electrons. The organic light-emitting compound moves into an excited state by the energy and emits light from energy when the organic light-emitting compound returns to the ground state from the excited state.
The most important factor determining luminous efficiency in an organic EL device is light-emitting materials. The light-emitting materials are required to have the following features: high quantum efficiency, high movement degree of an electron and a hole, and uniformality and stability of the formed light-emitting material layer. The light-emitting material is classified into blue, green, and red light-emitting materials according to the light-emitting color, and further includes yellow or orange light-emitting materials. Furthermore, the light-emitting material is classified into a host material and a dopant material in a functional aspect. Recently, an urgent task is the development of an organic EL device having high efficiency and long lifespan. In particular, the development of highly excellent light-emitting material over conventional materials is urgently required, considering the EL properties necessary for medium- and large-sized OLED panels. For this, preferably, as a solvent in a solid state and an energy transmitter, a host material should have high purity and a suitable molecular weight in order to be deposited under vacuum. Furthermore, a host material is required to have high glass transition temperature and pyrolysis temperature to achieve thermal stability, high electrochemical stability to achieve a long lifespan, easy formability of an amorphous thin film, good adhesion with adjacent layers, and no movement between layers.
In addition, a material having an excellent thermal stability and capable of improving the performance of an organic electroluminescent device, such as driving voltage, luminescent efficiency, and lifespan properties, in a hole transport layer, a buffer layer, an electron transport layer, and the like, is required to be developed.
The objective of the present disclosure is to provide an organic electroluminescent compound effective for producing an organic electroluminescent device having excellent thermal stability, low driving voltage, high luminous efficiency, and/or improved lifespan properties.
A compound having a low Tg may reduce the charge mobility in a thin film and degrade the performance of the OLED device. As a result of intensive studies, the present inventors have developed a novel organic electroluminescent compound having a planar main core, which can assist pi-pi stacking in a vacuum deposition layer to lead to rapid charge mobility, and having a high glass transition temperature (Tg) in spite of its relatively low molecular weight, which can provide excellent morphological stability. Specifically, the present inventors found that the above objective can be achieved by an organic electroluminescent compound represented by the following formula 1:

Hereinafter, the properties of the organic light-emitting diode (OLED) device comprising the compound of the present disclosure will be explained in detail, but is not limited by the following examples.
Device Examples 1 to 16: Producing an OLED device comprising a compound
according to the present disclosure as a host
OLED devices were produced by using the organic electroluminescent compound according to the present disclosure. A transparent electrode indium tin oxide (ITO) thin film (10 Ω/sq) on a glass substrate for an OLED device (GEOMATEC CO., LTD., Japan) was subjected to an ultrasonic washing with acetone, ethanol, and distilled water, sequentially, and then was stored in isopropanol. The ITO substrate was then mounted on a substrate holder of a vacuum vapor deposition apparatus. Compound HI-1 was introduced into a cell of the vacuum vapor deposition apparatus, and then the pressure in the chamber of the apparatus was controlled to 10-6 torr. Thereafter, an electric current was applied to the cell to evaporate the above-introduced material, thereby forming a first hole injection layer having a thickness of 80 nm on the ITO substrate. Next, compound HI-2 was introduced into another cell of the vacuum vapor deposition apparatus and was evaporated by applying an electric current to the cell, thereby forming a second hole injection layer having a thickness of 5 nm on the first hole injection layer. Compound HT-1 was then introduced into a cell of the vacuum vapor deposition apparatus and was evaporated by applying an electric current to the cell, thereby forming a first hole transport layer having a thickness of 10 nm on the second hole injection layer. Compound HT-2 was then introduced into another cell of the vacuum vapor deposition apparatus and was evaporated by applying an electric current to the cell, thereby forming a second hole transport layer having a thickness of 60 nm on the first hole transport layer. After forming the hole injection layer and the hole transport layer, a light-emitting layer was formed thereon as follows: The host material shown in Table 1 was introduced into one cell of the vacuum vapor depositing apparatus as a host, and compound D-39 was introduced into another cell as a dopant. The two materials were evaporated at a different rate and the dopant was deposited in a doping amount of 3 wt% based on the amount of the host to form a light-emitting layer having a thickness of 40 nm on the second hole transport layer. Compound ET-1 and compound EI-1 were then introduced into the other two cells and evaporated simultaneously to form an electron transport layer having a thickness of 35 nm on the light-emitting layer. After depositing compound EI-1 as an electron injection layer having a thickness of 2 nm on the electron transport layer, an Al cathode having a thickness of 80 nm was deposited on the electron injection layer by another vacuum vapor deposition apparatus. Thus, an OLED device was produced.
Comparative Example 1: Producing an OLED device comprising a
conventional compound as a host
An OLED device was produced in the same manner as in Device Example 1, except for using compound A as a host.
The driving voltage and luminous efficiency based on a luminance of 1,000 nits of the produced red OLED device, and the time taken to be reduced from 100% to 99% of the luminance (lifespan; T99) based on a luminance of 5,000 nits are provided in Table 1 below.
From Table 1 above, it can be seen that the OLED devices comprising the organic electroluminescent compound of the present disclosure have low driving voltage, high luminous efficiency, and/or improved lifespan properties compared to the OLED devices comprising a conventional organic electroluminescent compound. In addition, the organic electroluminescent compound of the present disclosure has a highly fused structure, and thus has a relatively high glass transition temperature (Tg) as compared with other organic electroluminescent compounds having similar molecular weights, thereby showing excellent thermal stability.
Comparative Example 2: Producing an OLED device not comprising an
electron buffer layer

A transparent electrode indium tin oxide (ITO) thin film (10 Ω/sq) on a glass substrate for an OLED device (GEOMATEC CO., LTD., Japan) was subjected to an ultrasonic washing with acetone and isopropyl alcohol, sequentially, and then was stored in isopropanol. The ITO substrate was then mounted on a substrate holder of a vacuum vapor deposition apparatus. Compound HI-1 was introduced into a cell of the vacuum vapor deposition apparatus, and then the pressure in the chamber of the apparatus was controlled to 10-7 torr. Thereafter, an electric current was applied to the cell to evaporate the above-introduced material, thereby forming a first hole injection layer having a thickness of 60 nm on the ITO substrate. Next, compound HI-2 was introduced into another cell of the vacuum vapor deposition apparatus and was evaporated by applying an electric current to the cell, thereby forming a second hole injection layer having a thickness of 5 nm on the first hole injection layer. Compound HT-1 was then introduced into a cell of the vacuum vapor deposition apparatus and was evaporated by applying an electric current to the cell, thereby forming a first hole transport layer having a thickness of 20 nm on the second hole injection layer. Compound HT-3 was then introduced into another cell of the vacuum vapor deposition apparatus and was evaporated by applying an electric current to the cell, thereby forming a second hole transport layer having a thickness of 5 nm on the first hole transport layer. After forming the hole injection layer and the hole transport layer, a light-emitting layer was formed thereon as follows: Compound FH-1 was introduced into one cell of the vacuum vapor depositing apparatus as a host, and compound FD-1 was introduced into another cell as a dopant. The two materials were evaporated at a different rate and the dopant was deposited in a doping amount of 2 wt% based on the total amount of the host and the dopant to form a light-emitting layer having a thickness of 20 nm on the second hole transport layer. Compound ET-1 and compound EI-1 were then introduced into the other two cells and evaporated simultaneously to form an electron transport layer having a thickness of 35 nm on the light-emitting layer. After depositing compound EI-1 as an electron injection layer having a thickness of 2 nm on the electron transport layer, an Al cathode having a thickness of 80 nm was deposited on the electron injection layer by another vacuum vapor deposition apparatus. Thus, an OLED device was produced. All the materials used for producing the OLED device were purified by vacuum sublimation at 10-6 torr.
Device Example 17: Producing an OLED device comprising a compound
according to the present disclosure as an electron buffer layer
An OLED device was produced in the same manner as in Comparative Example 2, except that the thickness of the electron transport layer was reduced to 30 nm, and the electron buffer layer comprising compound C-8 was inserted between the light-emitting layer and the electron transport layer.
The driving voltage and color coordinate based on a luminance of 1 mA/cm2 of the OLED device produced by Comparative Example 2 and Device Example 17, and the time taken to reduce the luminance from 100% to 90% (lifespan; T90) based on a luminance of 2,000 nits are provided in Table 2 below.
From Table 2 above, it can be seen that the OLED device of Device Example 17, in which the compound of the present disclosure is comprised in an electron buffer layer, has low driving voltage and improved lifespan properties compared to the OLED device of Comparative Example 2.
Device Example 18: Producing an OLED device comprising a compound
according to the present disclosure

The two materials were evaporated at the same rate, and compound D-39 was introduced into another cell as a dopant. The three materials were evaporated and the dopant was deposited in a doping amount of 3 wt% based on the total amount of the host and the dopant to form a light-emitting layer having a thickness of 40 nm on the second hole transport layer.
As a result, the efficiency was 20.8cd/A at a voltage of 4.3 V, red luminescence of 5000 cd/m2 was confirmed, and a minimum time taken to reduce the luminance from 100% to 97% based on a luminance of 5,000 nits was 137 hours.
The compounds used in the Comparative Examples and Device Examples are shown in Table 3 below.
