NOVEL COMPOUNDS FOR ORGANIC ELECTRONIC MATERIAL AND ORGANIC ELECTRONIC DEVICE USING THE SAME [Technical Field]

<i> The present invention relates to novel compounds for organic electronic material, and organic electronic devices comprising the same. More specifically, the invention relates to novel compounds for organic electronic material having high efficiency, and organic electronic devices which comprises the compounds in a hole transport layer or a hole injecting layer, or in an electroluminescent layer as the host for phosphor. [Background Art]

<2> Among display devices, electroluminescence devices (EL devices) are self-luminescent display devices showing the advantage of wide angle of view, excellent contrast and rapid response rate. Eastman Kodak developed in 1987 an organic EL device which employs a low molecular weight aromatic diamine and an aluminum complex as material for forming an EL layer, for the first time [Appl. Phys. Lett. 51, 913, 1987].

<3> An organic EL device is a device wherein, when charge is applied to an organic film formed between an electron injection electrode (cathode) and a hole injection electrode (anode), an electron and a hole form a pair and then become extinct with emitting light. A device can be formed on a transparent flexible substrate such as plastics. The device can be operated at a lower voltage (not more than 10 V) with relatively lower power consumption but excellent color purity, as compared to a plasma display panel or an inorganic EL display.

<4> The most important factor to determine the performances such as luminous efficiency, lifetime or the like in an organic EL device is electroluminescent material. Several properties required for such electroluminescent materials include that the material should have high fluorescent quantum yield in solid state and high mobility of electrons and holes, is not easily decomposed during vapor-deposition in vacuo, and forms uniform and stable thin film.

<5> Organic electroluminescent materials can be generally classified into high-molecular materials and low-molecular materials. The low-molecular materials include metal complexes and thoroughly organic electroluminescent materials which do not contain metal, from the aspect of molecular structure. Such electroluminescent materials include chelate complexes such as tris(8- quinolinolato)aluminum complexes, coumarin derivatives, tetraphenylbutadiene derivatives, bis(styrylarylene) derivatives and oxadiazole derivatives. From those materials, it is reported that light emission of visible region from blue to red can be obtained

<6> Three electroluminescent materials (for red, green and blue) are employed to realize a full-colored OLED display. The important issue is to develop red, green and blue electroluminescent materials with high efficiency and long life, in order to enhance the overall feature of the organic electroluminescent (EL) devices. The EL materials are classified into host materials and dopant materials from the aspect of their functions. It is generally known that a device structure having the most excellent EL properties can be fabricated with an EL layer prepared by doping a dopant to a host. Recently, development of organic EL devices with high efficiency and long life comes to the fore as an urgent subject, and particularly urgent is development of a material with far better EL properties as compared to conventional EL materials as considering EL properties required for a medium to large sized OLED panel.

<7> As a host material for phosphorescent light emitting material, 4,4'- N,N'-dicarbazole-biphenyl (CBP) has been most widely known up to the present, and OLED' s having high efficiency to which a hole blocking layer (such as BCP and BAIq) had been applied have been developed. Pioneer (Japan) or the like reported OLED' s of high performances which were developed by using bis(2- methyl-8-quinolinato)(p-phenylphenolato)aluminum (III) (BAIq) derivatives as the host. <9> Though the conventional materials are advantageous in view of light emitting property, they have low glass transition temperature and very poor thermal stability, so that the materials tend to be changed during high temperature vapor-deposition in vacuo. In an organic electroluminescent device (OLED), it is defined that power efficiency = (π/voltage) x current efficiency. Thus, the power efficiency is inversely proportional to the voltage, and the power efficiency should be higher in order to obtain lower power consumption of an OLED. In practice, an OLED employing phosphorescent electroluminescent (EL) material shows significantly higher current efficiency (cd/A) than an OLED employing fluorescent EL material. However, in case that a conventional material such as BAIq and CBP as host material of the phosphorescent EL material is employed, no significant advantage can be obtained in terms of power efficiency (lm/V) because of higher operating voltage as compared to an OLED employing a fluorescent material.

<10> Furthermore, there was no satisfactory result in view of life of an OLED, so that development of host material providing better stability and higher performance is still required.

<11> Further, hole injecting/transport materials including copper phthalocyanine (CuPc), 4,4'-bis[N-(l-naphthyl)-N-ρhenylamino]biphenyl (NPB) and MTDATA have been known.

<13> In view of improvement in durability of an organic electroluminescent device, it is reported that compounds having higher non-crystal linity give higher stability of thin film. Glass transition temperature (Tg) is employed as an index for non-crystal linity.

<14> It is recognized that conventional MTDATA does not show high non- crystal linity, having glass transition temperature of 76 ⁰ C. Thus, no satisfactory property could be obtained in terms of durability of the organic EL device, or luminous efficiency which comes from the hole injecting/transport property. [Disclosure] [Technical Problem]

<15> Thus, the object of the invention is to provide organic novel compounds for organic electronic material having the backbone to give better luminous efficiency and device life with appropriate color coordinate as compared to those of conventional host material of phosphor, with overcoming disadvantages of them.

<16> Another object of the invention is to provide organic electronic device employing the novel compounds for organic electronic material in the hole injecting layer, the hole transport layer or the electroluminescent layer.

<17> Still another object of the invention is to provide organic solar cells comprising the novel compounds for organic electronic material. [Technical Solution]

<363> <364> [Example 1] Manufacture of an OLED by using compounds for organic electronic material according to the invention (I)

<365> An OLED device was manufactured by using a compound for electronic material according to the invention. <366> First, a transparent electrode ITO thin film (15 /?) (2) prepared from glass for OLED (produced by Samsung Corning) (1) was subjected to ultrasonic washing with trichloroethylene, acetone, ethanol and distilled water, sequentially, and stored in isopropanol before use.

<367> Then, an ITO substrate was equipped in a substrate folder of a vacuum vapor-deposit device, and 4,4' ,4-tris(N,N-(2-naphthyl)- phenylamino)triphenylamine (2-TNATA) (of which the structure is shown below) was placed in a cell of the vacuum vapor-deposit device, which was then

-6 ventilated up to 10 torr of vacuum in the chamber. Electric current was applied to the cell to evaporate 2-TNATA, thereby providing vapor-deposit of a hole injecting layer (3) having 60 nm thickness on the ITO substrate.

<369> Then, to another cell of the vacuum vapor-deposit device, charged was N.N'-bist-naphtbyD-N.N'-diphenyl^^'-diamine (NPB) (of which the structure is shown below), and electric current was applied to the cell to evaporate NPB, thereby providing vapor-deposit of a hole transport layer (4) of 20 nm thickness on the hole injecting layer.

<37i> After forming a hole injecting layer and a hole transport layer, an electroluminescent layer was vapor-deposited as follows. To one cell of said vacuum eposit device, charged was a compound according to the inventi , Compound 279) as host material (which had been purified via sublima vacuo at 10 torr), and an electroluminescent dopant compound (e.g., (piq) ₂ Ir(acac)) was charged to another cell. The two substances were evaporated at different rates to carry out doping at a concentration of 4 to 10% by weight, thereby vapor-depositing an electroluminescent layer (5) with 30 nm of thickness on the hole transport layer.

373> Then, on the electroluminescent layer, bis(2-methyl-8-quinolinato)(p- phenylphenolato)aluminum (III) (BAIq) was vapor-deposited as a hole blocking layer with a thickness of 5 nm, tris(8-hydroxyquinoline)aluminum (III) (AIq) was vapor-deposited as an electron transport layer (6) with a thickness of 20 nm, and then lithium quinolate (Liq) was vapor-deposited as an electron injecting layer (7) with a thickness of 1 to 2 nm. Thereafter, an Al cathode (8) was vapor-deposited with a thickness of 150 nm by using another vacuum vapor-deposit device to manufacture an OLED.
