CROSS REFERENCE TO RELATED APPLICATIONS

TECHNICAL FIELD

The present invention relates to a novel organic light-emitting compound and an organic electroluminescent device using the same, and more particularly, to a novel indole-based compound having superior hole injection and transport capabilities, light-emitting capabilities, and the like, and an organic electroluminescent device which comprises the indole-based compound in one or more organic layers thereof so as to thereby achieve improved characteristics, such as light-emitting efficiency, driving voltage, and lifespan characteristics.


BACKGROUND ART

In a study on an organic electroluminescent (EL) device (hereinafter, simply referred to as ‘organic EL device’), which has continued from the start point of observation of an organic thin film light emission by Bernanose in the 1950s to blue electric light emission using an anthracene single crystal in 1965, an organic EL device having a lamination structure, which is divided into functional layers of a hole layer and a light emitting layer, was proposed by Tang in 1987, and the organic EL device has been developed in the form of introducing each characteristic organic layer into a device in order to manufacture the organic EL device having high efficiency and long lifespan, thereby leading to the development of specialized materials used therein.


When voltage is applied between two electrodes of the organic EL device, holes are injected into the organic layer at the anode and electrons are injected into the organic layer at the cathode. When the injected holes and electrons meet each other, an exciton is formed, and the exciton falls down to a bottom state to emit light. Materials used as the organic layer may be classified into a light-emitting material, a hole injection material, a hole transporting material, an electron transporting material, an electron injection material, and the like according to the function.


Materials for forming the light-emitting layer of the organic EL device may be divided into blue, green, and red light-emitting materials according to the light-emitting color. In addition, yellow and orange light-emitting materials are also used as a light-emitting material for implementing a much better natural color. Further, a host/dopant system may be used as a light-emitting material for the purpose of enhancing color purity and light-emitting efficiency through an energy transfer. Dopant materials may be divided into a fluorescent dopant using an organic material and a phosphorescent dopant in which a metal complex compound including heavy atoms such as Ir and Pt is used. Since the development of the phosphorescent material may theoretically enhance light-emitting efficiency by up to 4 times compared to the development of the fluorescent material, interests in not only phosphorescent dopant, but also phosphorescent host materials have been focused.


As the hole transporting layer, the hole blocking layer and the electron transporting layer, NPB, BCP, Alga and the like represented by the following Formulae have been widely known until now, and for the light-emitting material, anthracene derivatives have been reported as a phosphorescent dopant/host material. In particular, for the phosphorescent material having a great advantage in terms of enhancing the efficiency, metal complex compounds including Ir, such as Firpic, Ir(ppy)3 and (acac)Ir(btp)2 are used as blue, green and red dopant materials. Until now, CBP exhibits excellent characteristics as a phosphorescent host material.

However, the existing materials are advantageous in terms of light emitting characteristics, but fall short of a level that sufficiently satisfies the lifespan in the organic EL device caused by the low glass transition temperature and very poor thermal stability.

BEST MODE

The present invention provides a novel indole-based compound having a molecular weight larger than that of a material for an organic electroluminescent device [for example: 4,4-dicarbazolybiphenyl (hereinafter, represented as CBP)] in the related art, and excellent driving voltage characteristics and efficiency. The indole-based compound of the present invention has a structure of a compound represented by the above Formula 1. In the organic electroluminescent device, a host molecule needs to have an energy level larger than that of a dopant molecule in order to have high light-emitting efficiency, and the compound of the present invention has a wide band gap (sky blue to red) because a fused carbon ring or a fused heterocyclic moiety, preferably a fused heterocyclic moiety is connected to an indole-based basic structure, and the energy level is controlled by various substituents. Accordingly, the compound of Formula 1 may minimize energy loss during the light-emitting process, thereby exhibiting an effect of improving light-emitting efficiency. Furthermore, these characteristics of the compound may improve hole injection and transport capabilities, light-emitting efficiency, driving voltage, lifespan characteristics, and the like as well as phosphorescent characteristics of the device. Further, the compound of Formula 1 may be applied to the hole transporting layer, the electron transporting layer, and the like as well as the light-emitting layer according to the type of substituent to be introduced.


In particular, due to the indole-based moiety, the compound of Formula 1 may exhibit excellent characteristics as a material for a light-emitting host (a material for a blue, green and/or red phosphorescent host, or a material for a fluorescent dopant) compared to the CBP in the related art. Further, the molecular weight of the compound is significantly increased in the indole-based basic structure due to various aromatic ring substituents, so that the glass transition temperature is enhanced, and accordingly, the compound of Formula 1 may have higher thermal stability than that of the CBP in the related art. Therefore, a device including the compound of the present invention may greatly enhance durability and lifespan characteristics.


Herein, when a broad band-gap and thermal stability are considered, it is preferred that R1 to R4 of Formula 1 are each independently selected from the group consisting of hydrogen, a C6 to C60 aryl group (for example: phenyl, naphthyl, and bisphenyl), a heteroaryl group having 5 to 60 nuclear atoms (for example: pyridine), and a C6 to C60 arylamine group, and the C6 to C60 aryl group, the heteroaryl group having 5 to 60 nuclear atoms, and the C6 to C60 arylamine group of R1 and R2 may be substituted with one or more substituents selected from the group consisting of a C1 to C40 alkyl group, a C6 to C60 aryl group, and a heteroaryl group having 5 to 60 nuclear atoms.


In addition, when X1 and/or X2 of Formula 1 are(is) N(Ar1), C(Ar2)(Ar3), or Si(Ar4)(Ar5), it is preferred that Ar1 to Ar5 are each independently selected from the group consisting of a C6 to C60 aryl group, a heteroaryl group having 5 to 60 nuclear atoms, and a C6 to C60 arylamine group.

[Examples 1 to 30] Manufacture of Organic Electroluminescent Device

Compounds Inv-1 to Inv-26 and Inv-111 to Inv-114 synthesized in Synthesis Examples 1 to 26 and 111 to 114 were subjected to highly-pure sublimation purification by a typically known method, and then a green organic electroluminescent device was manufactured according to the following procedure.


First, a glass substrate on which a thin film of indium tin oxide (ITO) was coated to a thickness of 1500 Å was washed with distilled water under ultrasonic wave. After washed with distilled water, the glass substrate was ultrasonically washed with a solvent such as isopropyl alcohol, acetone and methanol, dried, and transferred to a UV ozone cleaner (Power sonic 405, Hwashin Technology Co., Ltd.), and then the substrate was cleaned for 5 minutes by using UV rays, and transferred to a vacuum deposition system.


An organic electroluminescent device was manufactured by laminating m-MTDATA (60 nm)/TCTA (80 nm)/each compound of Inv-1 to Inv-26 and Inv-111 to Inv-114+10% Ir(ppy)3 (300 nm)/BCP (10 nm)/Alq3 (30 nm)/LiF (1 nm)/A1 (200 nm) in this order on the ITO transparent electrode thus-prepared.

Example 1









As shown in Table 2, it can be seen that when compared with the green organic electroluminescent device using a CBP in the related art (Comparative Example 1), the green organic electroluminescent devices using the compounds (Inv-27 to Inv-110) according to the present invention as a light-emitting layer of the green organic electroluminescent device (Examples 31 to 114) show excellent performances in terms of efficiency and driving voltage.


[Examples 115 to 212] Manufacture of Organic Electroluminescent Device

Compounds Inv-115 to Inv-212 synthesized in Synthesis Examples 115 to 212 were subjected to highly-pure sublimation purification by a typically known method, and then a red organic electroluminescent device was manufactured according to the following procedure.


First, a glass substrate on which a thin film of indium tin oxide (ITO) was coated to a thickness of 1500 Å was washed with distilled water under ultrasonic wave. After washed with distilled water, the glass substrate was ultrasonically washed with a solvent such as isopropyl alcohol, acetone and methanol, dried, and transferred to a UV ozone cleaner (Power sonic 405, Hwashin Technology Co., Ltd.), and then the substrate was cleaned for 5 minutes by using UV rays, and transferred to a vacuum deposition system.


An organic electroluminescent device was manufactured by laminating m-MTDATA (60 nm)/NPB (20 nm)/each compound of Inv-115 to Inv-212+10% (piq)2Ir(acac) (30 nm)/BCP (10 nm)/Alq3 (30 nm)/LiF (1 nm)/Al (200 nm) in this order on the ITO transparent electrode thus-prepared.


[Comparative Example 2] Manufacture of Organic Electroluminescent Device

A red organic electroluminescent device was manufactured in the same manner as in Example 115, except that CBP was used instead of Compound Inv-115 as a light-emitting host material when a light-emitting layer is formed.


The structures of m-MTDATA, NPB, (piq)2Ir(acac) and CBP used in Examples 115 to 212 and Comparative Example 2 are as follows.
