Description

Organic light emitting device {Organic light emitting device}

The present invention relates to an organic light emitting diode having improved driving voltage, efficiency and lifetime.

In general, the organic light emitting phenomenon refers to a phenomenon in which electrical energy is converted into light energy using an organic material. An organic light emitting device using an organic light emitting phenomenon has a wide viewing angle, excellent contrast, and a fast response time, and has excellent luminance, driving voltage, and response speed characteristics, and thus many studies are being conducted.

An organic light emitting device generally has a structure including an anode, a cathode, and an organic material layer between the anode and the cathode. In order to increase the efficiency and stability of the organic light emitting device, the organic material layer is often composed of a multi-layered structure composed of different materials, and may include, for example, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer. In the structure of this organic light emitting device, when a voltage is applied between the two electrodes, holes are injected from the anode and electrons from the cathode are injected into the organic material layer, and when the injected holes and electrons meet, excitons are formed. When it falls back to the ground state, it glows.

The development of new materials for organic materials used in the organic light emitting device as described above is continuously required.

(9) and an example of an organic light emitting element composed of the cathode (4) is shown.

The organic light emitting device according to the present invention can be manufactured by sequentially stacking the above-described components. At this time, by using a physical vapor deposition (PVD) method such as sputtering or e-beam evaporation, depositing a metal or a metal oxide having conductivity or an alloy thereof on the substrate to form an anode And, after forming each of the above-described layers thereon, it can be manufactured by depositing a material that can be used as a cathode thereon. In addition to this method, an organic light emitting device may be manufactured by sequentially depositing a cathode material on a substrate and an anode material in the reverse order of the above configuration (WO 2003/012890). In addition, the light emitting layer may be formed by a solution coating method as well as a vacuum deposition method of a host and a dopant. Here, the solution coating method means spin coating, dip coating, doctor blading, inkjet printing, screen printing, spraying, roll coating, etc., but is not limited to these.

Example 1

A glass substrate coated with indium tin oxide (ITO) to a thickness of 1000 Å was put in distilled water in which detergent was dissolved and washed with ultrasonic waves. At this time, a Fischer Co. product was used as the detergent, and distilled water filtered through a second filter of a Millipore Co. product was used as the distilled water. After washing the ITO for 30 minutes, ultrasonic cleaning was performed twice with distilled water for 10 minutes. After washing with distilled water, ultrasonic cleaning was performed with solvents such as isopropyl alcohol, acetone, and methanol, dried, and transported to a plasma cleaner. In addition, after cleaning the substrate for 5 minutes using oxygen plasma, the substrate was transferred to a vacuum deposition machine.

The following compound HT-1 was vacuum deposited on the hole injection layer to form a hole transport layer having a thickness of 800 Å. Subsequently, an electron blocking layer was formed by vacuum depositing the following compound EB-1 to a film thickness of 150 Å on the hole transport layer. Subsequently, on the EB-1 deposited film, Compound 1-1 and Compound 2-1 as hosts and Compound Dp-7 as a dopant were vacuum co-evaporated at a weight ratio of 49:49:2 to form a red light emitting layer having a thickness of 400 Å. . A hole blocking layer was formed on the light emitting layer by vacuum depositing the following compound HB-1 to a film thickness of 30 Å. Subsequently, the following compound ET-1 and the following LiQ compound were vacuum deposited at a weight ratio of 2:1 on the hole blocking layer to form an electron injection and transport layer with a thickness of 300 Å. A negative electrode was formed by sequentially depositing lithium fluoride (LiF) to a thickness of 12 Å and aluminum to a thickness of 1000 Å on the electron injection and transport layer.

In the above process, the deposition rate of the organic material was maintained at 0.4 ~ 0.7 Å / sec, the deposition rate of lithium fluoride on the cathode was 0.3 Å / sec, and the deposition rate of aluminum was 2 Å / sec, and the vacuum degree during deposition was 2 × 10 ^-7 While maintaining ~ 5ⅹ10 ^-6 torr, an organic light emitting device was fabricated.

Comparative Examples 1 to 23

In the organic light emitting device of Example 1, only the compounds listed in Table 6 were used instead of Compound 1-1 and Compound 2-1 as a host, and the host and Compound Dp-7 were vacuum deposited at a weight ratio of 98: 2 to form a light emitting layer. Except for the above, an organic light emitting device was manufactured in the same manner as in Example 1.

Comparative Examples 24 to 51

In the organic light emitting device of Example 1, only the compounds listed in Table 7 were used instead of Compound 1-1 and Compound 2-1 as a host, and the host and Compound Dp-7 were vacuum deposited at a weight ratio of 98: 2 to form a light emitting layer.

Experimental example

[Table 7]

When current was applied to the organic light emitting devices manufactured in Examples 1 to 220 and Comparative Examples 1 to 51, the results of Tables 1 to 7 were obtained. The red organic light emitting device of Comparative Example 1 used materials widely used in the prior art, and used compound EB-1 as an electron blocking layer and compound Dp-7 as a dopant for the red light emitting layer. As shown in Table 6, when only the compound represented by Formula 2 of the present invention was used as a host of the light emitting layer as a comparative compound, the driving voltage generally increased and the efficiency and lifespan decreased compared to the combination of the present invention. In Table 7, only the compound represented by Formula 1 of the present invention was used as a host of the light emitting layer as a comparative compound, but the driving voltage, efficiency, and lifespan were improved compared to the case where Formula 2 was used as a host, but the dynamic voltage was higher than that of the combination of the present invention. and showed a decrease in efficiency and life.

From these results, when the combination of the compound represented by Formula 1 as the first host and the compound represented by Formula 2 as the second host of the present invention is used in an organic light emitting device, energy transfer to the red dopant in the red light emitting layer is well achieved. It was confirmed that the driving voltage is improved and the efficiency and lifetime are increased. After all, the combination of the compound represented by Formula 1 and the compound represented by Formula 2 of the present invention binds electrons and holes through a more stable balance in the light emitting layer than when used as a single host as a host like the comparative example compound to generate excitons. This is thought to be due to the increase in efficiency and lifetime. In conclusion, when the compound represented by Formula 1 and the compound represented by Formula 2 of the present invention are combined and co-evaporated and used as a host of a red light emitting layer, the driving voltage, luminous efficiency and lifetime characteristics of the organic light emitting device can be improved.
