(198) To the organic electroluminescent device manufactured according to the Examples and Comparative Examples prepared in this way, Electroluminescence (EL) characteristics were measured with a PR-650 of Photoresearch Co., by applying a forward bias DC voltage. As a result of the measurement, T95 life was measured at a standard luminance of 2,500 cd/m.sup.2 through life measuring apparatus manufactured by McScience. Table 6 shows the results of device fabrication and evaluation.

(199) The measuring apparatus can evaluate the performance of new materials compared to comparative compounds under identical conditions, without being affected by possible daily fluctuations in deposition rate, vacuum quality or other parameters.

(200) During the evaluation, one batch contains four identically prepared OLEDs including a comparative compound, and the performance of a total of 12 OLEDs is evaluated in 3 batches, so the value of the experimental results obtained in this way indicates statistical significance.

(202) As can be seen from the results in Table 6, when a red organic light emitting device is manufactured using the compound of the present invention as a phosphorescent host material, not only could the driving voltage of the organic light emitting device be lowered, but the efficiency and lifespan were significantly improved compared to the case of using Comparative Compound A to Comparative Compound E.

(203) As can be seen above, when a host of an emitting layer is formed by mixing multiple compounds, the properties were different depending on the type of the first compound and the second compound, and when the same compound was applied to the second compound, it was confirmed that there was a significant difference in properties depending on the type of the first compound. Likewise, there are differences in driving voltage, efficiency, and lifespan depending on the type of the second compound.

(204) Comparative Compounds A to Comparative Compound E have a similar skeleton to the compound of the present invention, but differ in that the skeleton of the present compound is further substituted with an additional substituent.

(205) In order to find out the difference in energy level of the compound according to the structural difference of these compounds, the energy levels of comparative compounds A to E and the similar compound P-1 of the present invention were measured using the DFT method of the Gaussian program (B3LYP/6-31g(D)). The measurement results are shown in Table 7.

(206) TABLE-US-00008 TABLE 7 compound HOMO (eV) P-1 5.724 Comparative 5.704 compound A Comparative 5.718 compound B Comparative 5.693 compound C Comparative 5.664 compound D Comparative 5.331 compound E

(207) Referring to Table 7, it can be seen that the compound of the present invention has a lower HOMO energy level than the comparative compounds.

(208) In the case of the compound of the present invention, it is the first host compound that transports electrons in the emitting layer and serves to accept and move electrons entering the emitting layer from the electron transport layer.

(209) In other words, the fact that the HOMO energy level of the compound of the present invention is lower than the HOMO energy level of Comparative Compound A to Comparative Compound E means that the electronic properties of the compound of the present invention are higher than those of the comparative compounds, as a result, it can be seen that electrons can be moved more effectively inside the emitting layer.

(210) In detail, if the HOMO energy level of the first host, which plays an electron transport role, is high, holes flowing from the hole transport layer to the emitting layer cannot be smoothly moved to the second host, electrons are more likely to be lost (exciton quenching) within the emitting layer rather than being transferred to the dopant to form exciton, thereby lowering luminous efficiency.

(211) As a result, the compound of the present invention has a lower HOMO energy level than the comparative, so holes flowing from the hole transport layer can be smoothly moved to the second host, and the electron mobility inside the emitting layer is maximized increasing the charge balance inside the emitting layer, and improving efficiency and lifespan.

(212) From Table 6 and Table 7, it can be seen that even if the compound has a similar composition, the compound of the present invention that satisfies all complex factors such as the type of substituent and the substitution position of the substituent shows a significant effect compared to other comparative compounds in organic electronic element. Through this, it can be seen that the compound of the present invention, which satisfies all specific compositions, exhibits a remarkable effect in organic electronic element compared to other comparative compounds not described in this specification.

(213) These results show that even in compounds with similar molecular components, depending on the type and substitution position of the substituent, the properties of compounds such as the hole characteristics, light efficiency characteristics, energy level, hole injection and mobility characteristics, charge balance of holes and electrons, volume density, and intermolecular distance of the molecule may vary significantly enough to be difficult to predict, additionally, it suggests that rather than one configuration affecting the overall results of the element, the performance of the element may vary due to complex factors.
