Definitions
- the present invention relates to novel organic electroluminescent compounds and an organic electroluminescent device using the same. More particularly, the organic electroluminescent compound is represented by Chemical Formula 1:
- electroluminescent (EL) devices are advantageous in that they providewide view angle, superior contrast and fast response rate as self-emissive display devices.
- Eastman Kodak first developed an organic EL device using a low-molecular-weight aromatic diamine and aluminum complex as a substance for forming an electroluminescent layer [ Appl. Phys. Lett. 51, 913, 1987].
- an organic EL device when a charge is applied to an organic layer formed between an electron injection electrode (cathode) and a hole injection electrode (anode), an electron and a hole are paired and exciton is generated. Light is emitted by using electroluminescence (phosphorescence or fluorescence) in a state that the exciton is inactivated.
- the organic EL device emits polarization of light at voltage of about 10V and high brightness of about 100 ⁇ 10,000cd/m2.
- the organic EL device has a feature in that light is emitted in a spectrum ranging from blue color to red color by simply selecting a fluorescent material.
- the organic EL device is advantageous in that it can be formed on a flexible transparent substrate such as plastic, is operable with relatively low voltage (10 V or lower) as compared to plasma display panels or inorganic EL displays, consumes less power, and provides excellent color.
- the electroluminescent material In an organic EL device, the most important factor that determines its performance including luminescence efficiency and operation life is the electroluminescent material. Some requirements of the electroluminescent material include high electroluminescence quantum yield in solid state, high electron and hole mobility, resistance to decomposition during vacuum deposition, ability to form uniform film and stability.
- Organic electroluminescent materials are 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.
- electroluminescent materials for red, green and blue
- OLED organic light-emitting diode
- 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. 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.
- the desired properties for the host material are high purity and appropriate molecular weight to enable vapor-deposition in vacuo.
- glass transition temperature and thermal decomposition temperature should be high enough to ensure thermal stability.
- the host material should have high electrochemical stability for providing long life. It is to be easy to form an amorphous thin film, with high adhesiveness to other adjacent materials but without interlayer migration.
- the organic EL device When the organic EL device is fabricated by doping technology, transferring energy from host molecule to dopant in an excited state does not achieve 100% and a host material as well as dopant emits light. In particular, since the host material emits light in a range of wavelength having larger visibility than the dopant in case of a red light emitting device, color purity is deteriorated due to dull light emission of the host material. If the technology is actually applied, it is required to increase luminescence life and improve durability.
- CBP is most widely known as a host material for a phosphorescent material.
- High-efficiency OLEDs using a hole blocking layer comprising BCP, BAlq, etc. are reported.
- High-performance OLEDs using BAlq derivatives as a host were reported by Pioneer (Japan) and others.
- the OLED devices do not have satisfactory operation life. Therefore, development of more stable, higher-performance host materials is required.
- an object of the present invention is to provide an organic electroluminescent compound having luminescence efficiency and device operation life improved over existing materials and having superior backbone with appropriate color coordinates in order to solve the aforesaid problems.
- Another object of the present invention is to provide a highly efficient and long life organic electroluminescent device employing the organic electroluminescent compound as an electroluminescent material.
- organic electroluminescent compound represented by following Chemical Formula 1 and an organic electroluminescent device using the same. Since the organic electroluminescent compound according to the present invention exhibits good luminous efficiency and excellent life property compared to the existing host material, it may be used to manufacture OLED devices having very superior operation life and consuming less power due to improved power efficiency.
