An organic light emission phenomenon is an example of a conversion of current into visible rays through an internal process of a specific organic molecule. The organic light emission phenomenon is based on the following mechanism. When organic material layers are interposed between an anode and a cathode, if voltage is applied between the two electrodes, electrons and holes are injected from the cathode and the anode into the organic material layer. The electrons and the holes which are injected into the organic material layer are recombined to form an exciton, and the exciton is reduced to a bottom state to emit light. An organic light emitting device which is based on the above mechanism typically comprises a cathode, an anode, and organic material layer(s) interposed between thereof, for example, organic material layers comprising a hole injection layer, a hole transport layer, a light emitting layer, and an electron transport layer, interposed therebetween.
The materials used in the organic light emitting device are mostly pure organic materials or complexes of organic material and metal. The material used in the organic light emitting device may be classified as a hole injection material, a hole transport material, a light emitting material, an electron transport material, or an electron injection material, according to its use. In connection with this, an organic material having a p-type property, which is easily oxidized and is electrochemically stable when it is oxidized, is mostly used as the hole injection material or the hole transport material. Meanwhile, an organic material having an n-type property, which is easily reduced and is electrochemically stable when it is reduced, is used as the electron injection material or the electron transport material. As the light emitting layer material, a material having both p-type and n-type properties is preferable, which is stable when it is oxidized and when it is reduced. Also a material having high light emission efficiency for conversion of the exciton into light when the exciton is formed is preferable.
In addition, it is preferable that the material used in the organic light emitting device further have the following properties.
First, it is preferable that the material used in the organic light emitting device have excellent thermal stability. The reason is that joule heat is generated by movement of electric charges in the organic light emitting device. NPB, which has recently been used as the hole transport layer material, has a glass transition temperature of 100° C. or lower, thus it is difficult to apply to an organic light emitting device requiring a high current.
Second, in order to produce an organic light emitting device that is capable of being actuated at low voltage and has high efficiency, holes and electrons which are injected into the organic light emitting device must be smoothly transported to a light emitting layer, and must not be released out of the light emitting layer. To achieve this, a material used in the organic light emitting device must have a proper band gap and a proper HOMO or LUMO energy levels. A LUMO energy level of PEDOT:PSS, which is currently used as a hole transport material of an organic light emitting device produced using a solution coating method, is lower than that of an organic material used as a light emitting layer material, thus it is difficult to produce an organic light emitting device having high efficiency and a long lifespan.
Moreover, the material used in the organic light emitting device must have excellent chemical stability, electric charge mobility, and interfacial characteristic with an electrode or an adjacent layer. That is to say, the material used in the organic light emitting device must be little deformed by moisture or oxygen. Furthermore, proper hole or electron mobility must be assured so as to balance densities of the holes and of the electrons in the light emitting layer of the organic light emitting device to maximize the formation of excitons. Additionally, it has to be able to have a good interface with an electrode comprising metal or metal oxides so as to assure stability of the device.
Accordingly, there is a need to develop an organic material having the above-mentioned requirements in the art.
Therefore, the present inventors aim to provide a novel compound that is capable of satisfying conditions required of a material which may be used for an organic light emitting device and an organic electronic device, for example, a proper energy level, electrochemical stability, and thermal stability, and is capable of largely improving a life time and efficiency of the organic electronic device, and an organic electronic device using the same.

In addition, the present invention provides a method for manufacturing the derivative that is represented by Formula 1. The method for manufacturing the compound according to the present invention is disclosed in the document [Journal of Tetrahedron 2005, 61, 1681-1691], and the compounds A and B are manufactured like the following Reaction Equation 1 according to the method disclosed in the above document, but the method for manufacturing the derivative that is represented by Formula 1 is not limited to the following Reaction Equation 1.

The method for manufacturing the compound of Formula 1 according to the present invention introduces X of Formula A manufactured in the above Equation under the Pd catalyst, introduces the bromo group with NBS or Br2, and introduces the substituent group R3 under the Pd catalyst to manufacture Formula 1.
The compound of Formula 1 is characterized in that it has a core structure in which at least one benzene ring is condensated in the carbazole structure.
The conjugation length of the compound has a close relationship with an energy band gap. In detail, the energy band gap is reduced as the conjugation length of the compound increases. As described above, since a conjugation structure is limited in the core structure of the compound of Formula 1, the core structure has a large energy band gap.
As described above, in the present invention, various substituent groups are introduced to L1, L2, X, Y1, or Y2 positions of the core structure having the large energy band gap so as to produce compounds having various energy band gaps. Generally, it is easy to control an energy band gap by introducing substituent groups into a core structure having a large energy band gap, but it is difficult to significantly control the energy band gap by introducing substituent groups into a core structure having a small energy band gap. Furthermore, in the present invention, it is possible to control HOMO and LUMO energy levels of the compound by introducing various substituent groups into L, X, or Y of the core structure.
Additionally, by introducing various substituent groups into the core structure, compounds having intrinsic characteristics of the substituent groups may be obtained. For example, substituent groups, which are frequently applied to hole injection layer material, hole transport layer material, light emitting layer material, and electron transport layer materials during the production of the organic light emitting device and the organic electronic device, are introduced into the core structure so as to produce substances capable of satisfying the requirements of each organic material layer. For example, the arylamino group, the thiophenyl group or the aryl group that is substituted with them may be introduced. Formula 1 in which the arylamino group or the thiophenyl group is introduced shows HOMO characteristic that is in the range of 5.6 to 5.1 eV, and it is very useful to use as the hole injection and hole transport layer.
Furthermore, various substituent groups are introduced into the core structure so as to precisely control the energy band gap, and to improve interfacial characteristics with organic material layers, thereby apply the compound to various fields.
In addition, by controlling the number of amine that is comprised in the substituent group B, it is possible to finely control HOMO and LUMO energy level and energy band gap, improve interfacial characteristics with organic materials, and make the purpose of material various.
In addition, if an appropriate substituent is introduced to the structure of Formula 1, energy band gap and stability can be ensured at a triplet state. From these results, various phosphorescence dopants from red color to blue color can be used and applied to light emitting layers of fluorescent and phosphorescent devices.
In addition, since the compound of Formula 1 has a high glass transition temperature (Tg), it has excellent thermal stability. Such increase in thermal stability is an important factor providing driving stability to the device.
Furthermore, the compound of Formula 1 may be used to form the organic material layer using a vacuum deposition process or a solution coating process during the production of the organic light emitting device. In connection with this, illustrative, but non-limiting, examples of the solution coating process comprise a spin coating process, a dip coating process, an inkjet printing process, a screen printing process, a spray process, and a roll coating process.
The organic electronic device of the present invention may be produced using known materials through a known process, modified only in that at least one layer of organic material layer(s) comprise the compound of the present invention, that is, the compound of Formula 1. A compound according to the present invention may be used as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material and the like, and it is more preferable that it is used as a hole injection material and a hole transport material in an organic electronic device according to the present invention. In addition, on the basis of the application of the compound according to the present invention to the organic light emitting device, those who are skilled in the art can use the compound according to the present invention in other organic electronic devices. The organic electronic device according to the present invention comprises an organic light emitting device, an organic phosphorescent device, an organic solar cell, an organic photoconductor and an organic transistor.
The organic material layer(s) of the organic electronic device according to the present invention may have a single layer structure, or alternatively, a multilayered structure in which at least two organic material layers are layered. For example, the organic light emitting device of the present invention may comprise a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer as the organic material layer(s). However, the structure of the organic light emitting device is not limited to this, but may comprise a smaller number of organic material layers. The structure of the organic light emitting device according to the present invention is illustrated in
Furthermore, the organic light emitting device of the present invention may be produced, for example, by sequentially layering a first electrode, organic material layer(s), and a second electrode on a substrate. In connection with this, a physical vapor deposition (PVD) method, such as a sputtering method or an e-beam evaporation method, may be used, but the method is not limited to these.
The method for manufacturing the compound of Formula 1 and the manufacturing of an organic light emitting device using the same will be described in detail in Preparation Examples and Examples. However, the following Preparation Examples and Examples are set forth to illustrate the present invention, but the scope of the present invention is not limited thereto.

A glass substrate (corning 7059 glass) on which a thin film of ITO (indium tin oxide) was coated to a thickness of 1,000 Å was immersed in distilled water having a detergent dissolved therein to wash the substrate with ultrasonic waves. The detergent as used herein was a product commercially available from Fisher Co. and the distilled water was one which had been twice filtered by using a filter commercially available from Millipore Co. ITO was washed for 30 minutes, and then washing with ultrasonic waves was repeated twice for 10 minutes by using distilled water. After the completion of washing with distilled water, washing with ultrasonic waves was subsequently carried out by using solvents such as isopropyl alcohol, acetone and methanol, and the resultant product was dried.
On the ITO transparent electrode thus prepared, hexanitrile hexaazatriphenylene was coated to thicknesses of 500 Å by thermal vacuum deposition to form a hole injecting layer. After the compound (400 Å) that was the material transporting the holes, synthesized in Preparation Example 1, and represented by Formula 1-1-1 was deposited under the vacuum thereon, the host H1 and the dopant compound D1 were deposited under the vacuum as the light emitting layer in a thickness of 300 Å. Thereafter, the E1 compound (300 Å) was deposited by heating under the vacuum as the electron injection and the transport layer. On the electron transport layer, lithium fluoride (LiF) in a thickness of 12 Å and aluminium in a thickness of 2,000 Å were subsequently deposited to form a cathode, thereby manufacturing the organic light emitting device.
In the above process, the deposition speed of the organic material was maintained at 1 Å/sec, that of lithium fluoride was maintained at 0.2 Å/sec, and that of aluminium was maintained at 3 to 7 Å/sec.

The same experiment was carried out, except that HT1 was used instead of the compound that was synthesized as the hole transport layer in Preparation Example and represented by Formula 1-1-1 in Example 1-1.

On the ITO transparent electrode thus prepared, hexanitrile hexaazatriphenylene was coated to thicknesses of 200 Å by thermal vacuum deposition to form a hole injecting layer. After the compound (300 Å) that was the material injecting the holes, synthesized in Preparation Example 10, and represented by Formula 1-1-25 was deposited under the vacuum thereon, NPB (400 Å) was deposited under the vacuum as the hole transport layer. The host H1 and the dopant compound D1 were deposited under the vacuum as the light emitting layer in a thickness of 300 Å. Thereafter, the E1 compound (300 Å) was subsequently deposited by heating under the vacuum as the electron injection and the transport layer. On the electron transport layer, lithium fluoride (LiF) in a thickness of 12 Å and aluminium in a thickness of 2,000 Å were subsequently deposited to form a cathode, thereby manufacturing the organic light emitting device.
In the above process, the deposition speed of the organic material was maintained at 1 Å/sec, that of lithium fluoride was maintained at 0.2 Å/sec, and that of aluminium was maintained at 3 to 7 Å/sec.
The organic light emitting device was manufactured by using the compounds that were manufactured in Preparation Examples and represented by Formula 5-1-1, Formula 5-1-21, Formula 5-21-21, Formula and 5-21-3, and Formula 1-51-37 instead of the compound that was represented by Formula 1-1-25 in Example 2-1, and using the compound E1, and the test results are described in the following Table 2.
As shown in Examples, in the case of when the manufactured compounds are used as the hole transport layer (HTL), in Formula 1, it is preferable that X that is the 9-position substituent of N-carbazole is not the substituted or unsubstituted arylaminoaryl group, but X that is the 9-position substituent of N-carbazole was is the aryl group such as the phenyl group, and the biphenyl group, and it is preferable that R1 to R8 are the substituted or unsubstituted arylamino group, or the arylaminoarylene group.
In Formula 1, the preferable compounds as the hole injection layer (HIL) are materials that have substituents having the HOMO values capable of being smaller than that of the hole transport layer (HTL). That is, in order to allow the carrier to easily move from the anode such as ITO (indium tin oxide) to the hole transport layer (HTL), it is preferable that the length of conjugation is increased, or the materials comprising the arylamino group, the arylaminoaryl group, or the thiophenyl group are substituted so as to change their properties into the p-type materials. In particular, the compounds according to the present invention can be used as the hole injection layer, thus obtaining the excellent result.
In Comparative Example 1 of Table 1, in the case of the compound of H1, the arylaminoallyl group is disposed at carbazole-N-9. On the other hand, the compounds of examples of Table 1, Table 2 and Table 3 are the arylamino group and the arylaminoaryl group, of which R1 to R8 are substituted or unsubstituted, and the aryl group which is substituted by thiophenyl, and most of them are the compound in which X of carbazole-N-9 is the aryl group. From the results, it can be seen that more excellent performance results are obtained.
The reason for this is that when the electrons moving from the electrode through the electron injection and the electron transport layer (ETL) to the light emitting layer (EML) reach the interface of the hole transport layer (HTL), the aryl group is more stable than the arylamino group. The arylamino group is stable in the hole but weak to the electron, such that it can negatively affect efficiency and a lifespan of the organic electronic device.
On the other hand, in the compound H1, since the distribution of electrons is disposed at the arylamino group, phenyl group of the N-9-positions, stability may be low. It can be deemed that the electrons distributed at the aryl group such as the phenyl group, naphthyl group and the biphenyl group, not the electrons at the arylamino group can provide stability to the organic electronic device. Accordingly, the compounds that are represented by Formula 1 used as the hole transport layer (HTL), and as the substituent at the carbazole-N-9-position, the aryl group or the heteroaryl group is preferable, and particularly, the aryl group is preferable. In the case of when the compounds that are represented by Formula 1 are used as the hole injection layer (HIL), since the hole transport layer (HTL) is disposed between the hole injection layer (HIL) and the light emitting layer (EML), even though the aryl group in which the arylamino group is introduced at the carbazole-N-9-position is used as the hole injection layer (HIL), the hole transport layer (HTL) can stop the electrons, such that it cannot largely affect the device even though the substitutents such as the arylamino group and the thiophenyl group are introduced. In particular, since the substitutents such as the arylamino group and the thiophenyl group can produce the holes, they are preferable as the hole transport layer (HIL).

On the ITO transparent electrode thus prepared, hexanitrile hexaazatriphenylene was coated to thicknesses of 500 Å by thermal vacuum deposition to form a hole injecting layer. After the compound (400 Å) that was the material transporting the holes, synthesized in Preparation Example 2-1-1, and represented by Formula 1-21-1 was deposited under the vacuum thereon. The host H2 and the dopant compound D3 (doping concentration 14%) were deposited under the vacuum as the light emitting layer in a thickness of 300 Å. Thereafter, the E1 compound (300 Å) was subsequently deposited by heating under the vacuum as the electron injection and the transport layer. On the electron transport layer, lithium fluoride (LiF) in a thickness of 12 Å and aluminium in a thickness of 2,000 Å were subsequently deposited to form a cathode, thereby manufacturing the organic light emitting device.
In the above process, the deposition speed of the organic material was maintained at 1 Å/sec, that of lithium fluoride was maintained at 0.2 Å/sec, and that of aluminium was maintained at 3 to 7 Å/sec.
