FIELD OF DISCLOSURE

The present specification relates to an organic light emitting device.

BACKGROUND

In general, an organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy by using an organic material. An organic light emitting device using the organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer interposed therebetween. Here, the organic material layer has in many cases a multi-layered structure composed of different materials in order to improve the efficiency and stability of the organic light emitting device, and for example, may be composed 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 such a structure of the organic light emitting device, if a voltage is applied between the two electrodes, holes are injected from the anode into the organic material layer and 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 down again to a ground state.

There is a continuous need for developing a new material for the aforementioned organic light emitting device.

DETAILED DESCRIPTION

Hereinafter, the present specification will be described in more detail.

The present specification provides an organic light emitting device including a light emitting layer including compounds represented by Formulae 1-1 to 1-3, and a compound represented by Formula 2. Specifically, the compounds represented by Formulae 1-1 to 1-3 and the compound represented by Formula 2 are included as a host and a dopant, respectively.

The compound represented by Formula 2 has excellent light emission characteristics due to a narrow full-width at half-maximum, but the service life performance thereof is slightly insufficient.

Low voltage and high efficiency properties are provided when the compounds represented by Formulae 1-1 to 1-3 are used as a host of a light emitting layer of an organic light emitting device, as the driving voltage is stabilized from good movement and injection of holes and electrons due to the structures of Formulae 1-1 to 1-3.

Further, the compounds of Formulae 1-1 to 1-3 include deuterium. When the compounds of Formulae 1-1 to 1-3 include deuterium, the service life of a device is improved. Specifically, when hydrogen is replaced with deuterium, chemical properties of the compound are rarely changed. However, since the atomic weight of deuterium is twice that of hydrogen, physical properties of a deuterated compound may be changed. As an example, a compound substituted with deuterium has a lower level of vibrational energy. Quantum calculations revealed changes in the vibrational energy according to the deuterium substitution rate of the compound, but a vibrational energy of about 2 kcal/mol was decreased constantly for each number of deuterium substitutions. Accordingly, the compound substituted with deuterium may prevent a decrease in quantum efficiency caused by a decrease in intermolecular Van der Waals force or a collision due to intermolecular vibration. In addition, the stability of the compound may be improved by a C-D bond, which is stronger than a C—H bond.

The organic light emitting device of the present invention may include compounds represented by Formulae 1-1 to 1-3 and a compound represented by Formula 2 together, thereby improving a service life problem while maintaining excellent light emission characteristics of the compound of Formula 2.

The compounds of Formulae 1-1 to 1-3 including deuterium may be prepared by a publicly-known deuteration reaction. According to an exemplary embodiment of the present specification, the compounds represented by Formulae 1-1 to 1-3 may be formed using a deuterated compound as a precursor, or deuterium may also be introduced into a compound via a hydrogen-deuterium exchange reaction in the presence of an acid catalyst using a deuterated solvent.

In the present specification, N % substitution with deuterium means that N % of hydrogen available in the corresponding structure is substituted with deuterium. For example, 25% substitution of dibenzofuran with deuterium means that two of eight hydrogens of dibenzofuran are substituted with deuteriums.

In the present specification, the degree of deuteration may be confirmed by a publicly-known method such as nuclear magnetic resonance spectroscopy (1H NMR) or GC/MS.

In Formulae 1-1 to 1-3 and 2 of the present specification, the substitution includes being substituted with deuterium even when the substituted substituent is not specified.

After the ITO was washed for 30 minutes, ultrasonic washing was conducted twice repeatedly using distilled water for 10 minutes. After the washing using distilled water was completed, ultrasonic washing was conducted by using isopropyl alcohol, acetone, and methanol solvents, and the resulting product was dried and then transported to a plasma washing machine. Furthermore, the substrate was cleaned by using oxygen plasma for 5 minutes, and then was transported to a vacuum deposition machine.

The following HT-A was vacuum deposited to have a thickness of 1250 Å on the hole injection layer, thereby forming a hole transport layer. The following HT-B was vacuum deposited to have a thickness of 150 Å on the hole transport layer, thereby forming an electron blocking layer.

Subsequently, the following compound BD-1 as a blue light emitting dopant was vacuum deposited at 4 wt % based on a total weight of the light emitting layer and the following BH-1 as a host was vacuum deposited to a thickness of 200 Å on the electron blocking layer, thereby forming a light emitting layer.

LiQ was vacuum deposited to have a thickness of 5 Å on the second electron transport layer, thereby forming an electron injection layer. Aluminum and silver were deposited at a weight ratio of 10:1 to have a thickness of 220 Å on the electron injection layer, and aluminum was deposited to have a thickness of 1,000 Å thereon, thereby forming a cathode.

Examples 95 to 98 and Comparative Example 6

Organic light emitting devices of Examples 95 to 98 and Comparative Example 6 were each manufactured in the same manner as in Example 1, except that in Example 1, compounds described in the following Table 2 were used as dopants of the light emitting layer instead of Compound BD-1, and compounds described in the following Table 2 were used as host materials instead of BH-1.

A weight ratio of the first host and the second host of the light emitting layer is 50:50.

Voltages and efficiencies (cd/A) when a current density of 10 mA/cm2 was applied to the organic light emitting devices in Examples 95 to 98 and Comparative Example 6 and service lives (T95) when a current density of 20 mA/cm2 was applied to the devices were measured, and the results are shown in the following Table 2. In this case, for T95, a time taken for the luminance to decrease to 95% when the initial luminance at the current density of 20 mA/cm2 is set to 100% was shown as the ratio based on Comparative Example 1.

As can be seen in the device results in Tables 1 and 2, when an organic light emitting device was constructed by combining a host material represented by any one of [Formula 1-1] to [Formula 1-3] according to an exemplary embodiment of the present specification and a dopant material represented by [Formula 2], the organic light emitting device, which was better in both the efficiency and service life performance of a device than other devices which were not constructed by the combination, was constructed.

From the results of Example 16, Example 25, Example 26, Examples 34 to 37, and Examples 45 to 50, it was confirmed that even in a device constructed using a host compound in which a compound was partially substituted with deuterium, a device having a long service life was constructed, and it was confirmed that even when a compound in which only one host of the two hosts was substituted with deuterium was used as in Example 98, a device having a long service life was constructed.

In addition, from Example 54, Examples 91 to 94, and Comparative Example 4, it was confirmed that when the compound was partially substituted with deuterium at a substitution rate of at least 30% or more, a device having a long service life was constructed.

Further, from Examples 15 and 16, it could be seen that when the skeleton was the same and the deuterium substitution rate was similar, the service life when deuterium was linked to anthracene was increased.
