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 washed for 30 minutes, and ultrasonic washing was then repeated twice for 10 minutes by using distilled water. After the washing with distilled water was completed, the substrate was ultrasonically washed with isopropyl alcohol, acetone, and methanol solvent, 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 as a hole injection layer, but the following compound A-1 was p-doped in an amount of 1.5% by weight. The following compound HT-1 was vacuum deposited on the hole injection layer to form a hole transport layer with a film thickness of 800 Å. Then, the following compound EB-1 was vacuum deposited to a film thickness of 150 Å on the hole transport layer to form an electron blocking layer. Then, the following compound 1-2 and the following compound Dp-7 were vacuum deposited in a weight ratio of 98:2 on the EB-1 deposited film to form a red light emitting layer with a thickness of 400 Å. The following compound HB-1 was vacuum deposited to a thickness of 30 Å on the light emitting layer to form a hole blocking layer. Then, the following compound ET-1 and the following compound LiQ were vacuum deposited in a ratio of 2:1 on the hole blocking layer to form an electron injection and transport layer with a thickness of 300 Å. Lithium fluoride (LiF) and aluminum were sequentially deposited to have a thickness of 12 Å and 1000 Å, respectively, on the electron injection and transport layer to form a cathode.
In the above-mentioned processes, the deposition rates of the organic materials were maintained at 0.4 to 0.7 Å/sec, the deposition rates of lithium fluoride and the 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 to 5*10−6 torr.
The organic light emitting devices were manufactured in the same manner as in Comparative Example 1, except that instead of Compound 1-2 as a host, the first host and the second host listed in Table 1 below were co-deposited at a weight ratio of 1:1 and used.
The organic light emitting devices were manufactured in the same manner as in Comparative Example 1, except that the host material shown in Table 2 was used instead of Compound 1-2 as a host, and the compound shown in Table 2 below was used instead of Compound EB-1 as the electron blocking layer material.
The organic light emitting devices were manufactured in the same manner as in Comparative Example 1, except that instead of Compound 1-2 as a host, the first host and the second host listed in Table 3 below were co-deposited at a weight ratio of 1:1 and used.
Compound B-1 to Compound B-12 in Table 3 are as follows:
The organic light emitting devices were manufactured in the same manner as in Comparative Example 1, except that instead of Compound 1-2 as a host, the first host and the second host listed in Table 4 below were co-deposited at a weight ratio of 1:1 and used.
Compound C-1 to Compound C-12 in Table 4 are as follows:
The voltage, efficiency, and lifetime were measured (based on 15 mA/cm2) by applying a current to the organic light emitting devices manufactured in Examples 1 to 155 and Comparative Examples 1 to 227, 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 according to Examples 1 to 155 and Comparative Examples 1 to 227, the results of Tables 1 to 4 above were obtained. In the organic light emitting device of Comparative Example 1, a material that has been widely used conventionally was used.
In Comparative Examples 2 to 61, the organic light emitting devices were manufactured by using the compound of Chemical Formula 2 of the present disclosure as the electron blocking layer, and using a single host as the light emitting layer in the same manner as in Comparative Example 1. When the compound of Chemical Formula 1 and the compound of Chemical Formula 2 were co-deposited and used as the light emitting layer as in Example of Table 1, it was confirmed that the driving voltage decreased and the efficiency and lifetime increased as compared with Comparative Example of Table 2.
Further, when Comparative Example compounds B-1 to B-12 and the compound of Chemical Formula 2 of the present disclosure were co-deposited and used as the light emitting layer as shown in Table 3, the result showed that the driving voltage generally increased and the efficiency and lifetime decreased as compared with a combination of the present disclosure. As shown in Table 4, 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 the light emitting layer, the result showed that the driving voltage increased and the efficiency and lifetime decreased.
From these results, it can be seen that when the compound of Chemical Formula 1 as the first host and the compound of Chemical Formula 2 as the second host were used in combination, energy transfer to the red dopant in the light emitting layer was well performed, thereby improving the driving voltage and increasing the efficiency and lifetime. In addition, it can be inferred that the combination of the compounds of Examples can form a more stable balance within the light emitting layer than the combination of the compounds of Comparative Examples to form excitons by the combination of electrons and holes, thereby further improving the efficiency and lifetime of the manufactured organic light emitting devices.
That is, when the compound of Chemical Formula 1 and the compound of Chemical Formula 2 of the present disclosure were used in combination as a host of the light emitting layer, the driving voltage, luminous efficiency, and lifetime characteristics of the organic light emitting devices could be improved.
