The present disclosure relates to an organic light emitting device having improved driving voltage, efficiency and lifetime.
In general, an organic light emitting phenomenon refers to a phenomenon where electric energy is converted into light energy by using an organic material. The organic light emitting device using the organic light emitting phenomenon has characteristics such as a wide viewing angle, an excellent contrast, a fast response time, an excellent luminance, driving voltage and response speed, and thus many studies have proceeded.
The organic light emitting device generally has a structure which comprises an anode, a cathode, and an organic material layer interposed between the anode and the cathode. The organic material layer frequently has a multilayered structure that comprises different materials in order to enhance efficiency and stability of the organic light emitting device, and for example, the organic material layer can be formed of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer and the like. In the structure of the organic light emitting device, if a voltage is applied between two electrodes, the holes are injected from an anode into the organic material layer and the electrons are injected from the cathode into the organic material layer, and when the injected holes and electrons meet each other, an exciton is formed, and light is emitted when the exciton falls to a ground state again.
There is a continuing need for the development of a new material for an organic material used in the organic light emitting device as described above.
It is an object of the present disclosure to provide an organic light emitting device having improved driving voltage, efficiency and lifetime.

A glass substrate on which a thin film of ITO (indium tin oxide) was coated in a thickness of 1000 Å was put into distilled water containing a detergent dissolved therein and ultrasonically washed. In this case, the detergent used was a product commercially available from Fischer Co. and the distilled water was one which had been twice filtered by using a filter commercially available from Millipore Co. The ITO was cleaned for 30 minutes, and ultrasonic cleaning was then repeated twice for 10 minutes by using distilled water. After the cleaning with distilled water was completed, the substrate was ultrasonically washed with the solvents of isopropyl alcohol, acetone, and methanol, and dried, after which it was transported to a plasma cleaner. Then, the substrate was cleaned with oxygen plasma for 5 minutes, and then transferred to a vacuum evaporator.
On the ITO transparent electrode thus prepared, the following compound HI-1 was formed to a thickness of 1150 Å as a hole injection layer, but the following compound A-1 was p-doped at a concentration of 1.5 wt. %. The following compound HT-1 was vacuum deposited on the hole injection layer to form a hole transport layer with a layer thickness of 800 Å. Then, the following compound EB-1 was vacuum deposited on the hole transport layer to a layer thickness of 150 Å to form an electron blocking layer. Then, Compound 1-1 and Compound 2-1 as the host and the following Compound Dp-7 as the dopant were vacuum deposited in a weight ratio of 49:49:2 on the EB-1 deposited layer to form a red light emitting layer with a layer thickness of 400 Å. The following compound HB-1 was vacuum deposited on the light emitting layer to a layer thickness of 30 Å to form a hole blocking layer. The following compound ET-1 and the following compound LiQ were vacuum deposited in a weight ratio of 2:1 on the hole blocking layer to form an electron injection and transport layer with a layer thickness of 300 Å. Lithium fluoride (LiF) and aluminum were sequentially deposited to have a thickness of 12 Å and 1,000 Å, respectively, on the electron injection and transport layer, thereby forming a cathode.
In the above-mentioned processes, the deposition rates of the organic materials were maintained at 0.4˜0.7 Å/sec, the deposition rates of lithium fluoride and aluminum of the cathode were maintained at 0.3 Å/sec and 2 Å/sec, respectively, and the degree of vacuum during the deposition was maintained at 2×10−7˜5×10−6 torr, thereby manufacturing an organic light emitting device.
The organic light emitting devices were manufactured in the same manner as in Example 1, except that in the organic light emitting device of Example 1, the first host and the second host described in Tables 1 to 5 below were used instead of Compound 1-1 and Compound 2-1.
The organic light emitting devices were manufactured in the same manner as in Example 1, except that in the organic light emitting device of Example 1, the first host described in Tables 6 and 7 below were used instead of Compound 1-1. The structures of Compounds B-1 to B-12 of Tables 6 and 7 are as follows.
The organic light emitting devices were manufactured in the same manner as in Example 1, except that in the organic light emitting device of Example 1, the second host described in Tables 8 to 10 below were used instead of Compound 2-1. The structures of Compounds C-1 to C-12 of Tables 8 to 10 are as follows.
The voltage and efficiency were measured (based on 15 mA/cm2) by applying a current to the organic light emitting devices manufactured in Examples 1 to 220 and Comparative Examples 1 to 156, and the results are shown in Tables 1 to 4 below. Lifetime T95 means the time required for the luminance to be reduced to 95% of the initial luminance (6,000 nit).
When a current was applied to the organic light emitting devices manufactured in Examples 1 to 220 and Comparative Examples 1 to 156, the results shown in Tables 1 to 10 were obtained. In the red organic light emitting device of Comparative Example 1, conventionally widely used materials were used, and Compound EB-1 was used as the electron blocking layer, and Dp-7 was used as the dopant for the red light emitting layer. When Comparative Examples Compounds B-1 to B-12 and the compound of Chemical Formula 2 of the present disclosure were co-deposited and used as a red light emitting layer as shown in Table 6 and Table 7, the driving voltage generally increased and the efficiency and lifetime decreased as compared with the combination of the present disclosure. Even when Comparative Example Compounds C-1 to C-12 and the compounds of Chemical Formula 1 of the present disclosure were co-deposited and used as a red light emitting layer as shown in Tables 8 to 10 above, the driving voltage increased, and the efficiency and lifetime decreased.
From the above results, it could be confirmed that when a combination of the compound of Chemical Formula 1, which is a first host, and the compound of Chemical Formula 2, which is a second host of the present disclosure, is used in an organic light emitting device, it is advantageous for energy transfer to the red dopant in the red light emitting layer, thus improving the driving voltage and increasing the efficiency and lifetime. Ultimately, this is considered to be because as compared with the combination with Comparative Example Compound, the combination of the compound of Chemical Formula 1 and the compound of Chemical Formula 2 of the present disclosure allows electrons and holes to combine to form excitons through a more stable balance within the light emitting layer, thus increasing efficiency and lifetime. In conclusion, it was confirmed that when the compound of Chemical Formula 1 and the compound of Chemical Formula 2 were combined and co-evaporated and used as a host for the red light emitting layer, the driving voltage, luminous efficiency and lifetime characteristics of the organic light emitting devices can be improved
