Synthesis Example 2

(177) The compound represented by Formula 2 or Formula 3 can be prepared by a known synthetic method (named reaction) or by referring to published patent publications, such as Korean Patent Registration No. 10-2395819 and U.S. Patent Publication No. 2023-0129535, but is not limited thereto.

(178) In the above, exemplary synthesis examples of the present invention represented by Formula 1 have been described, but these are all based on the Buchwald-Hartwig cross coupling reaction, Miyaura boration reaction, Suzuki cross-coupling reaction, Intramolecular acid-induced cyclization reaction (J. mater. Chem. 1999, 9, 2095.), Pd(II)-catalyzed oxidative cyclization reaction (Org. Lett. 2011, 13, 5504), and PPh.sub.3-mediated reductive cyclization reaction (J. Org. Chem. 2005, 70, 5014.), and it will be easily understood by those skilled in the art that the reaction proceeds even when other substituents defined in Formula 1 are bonded in addition to the substituents specified in the specific synthesis examples.

(179) The FD-MS values of compounds N-1 to N-128 and S-1 to S-120 of the present invention manufactured according to Synthetic Example 2 as described above are as shown in Tables 4 and 5.

(182) In the above, exemplary synthesis examples of the present invention represented by Formula 1, Formula 2, and Formula 3 have been described, but these are all based on the Buchwald-Hartwig cross coupling reaction, Miyaura boration reaction, Suzuki cross-coupling reaction, Intramolecular acid-induced cyclization reaction (J. mater.

(189) The electroluminescence (EL) characteristics were measured using PR-650 from Photoresearch by applying a forward bias DC voltage to the organic electroluminescence devices manufactured by the examples and comparative examples manufactured in this way. As a result of the measurement, the T95 lifespan was measured using a lifespan measuring device manufactured by Max Science at a standard brightness of 2500 cd/in.sup.2. Table 6 shows the results of the device fabrication and evaluation.

(190) 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.

(191) During the evaluation, one batch contains 4 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.

(193) As can be seen from the results in Table 6, when a red organic emitting device was manufactured using the compound of the present invention as a phosphorescent host material, not only was the driving voltage of the organic light emitting device lowered compared to when Comparative Compounds A to C were used, but the efficiency and lifespan were also significantly improved.

(194) As can be seen from the above, when a plurality of compounds are mixed to form a host for the emitting layer, the characteristics differ depending on the type of the first compound and the second compound, and when the same compound is applied to the second compound, it can be confirmed that there is a significant difference in the characteristics depending on the type of the first compound. Similarly, the second compound shows differences in operating voltage, efficiency, and lifespan depending on the type.

(195) Comparative compounds A to C have a similar skeleton to the compound of the present invention, but differ in the substitution position and type of substituent.

(196) The compound of the present invention must have 1-naphthyl group bonded to a triazine and the 2-naphthyl group as a second naphthyl group, and specific aryl substituents must be bonded to different rings of each of the two naphthyl groups. That is, the compound of the present invention is characterized in that, in the case of the compound of the present invention, phenyl is substituted at positions 5 to 8 of the 1-naphthyl group substituted with triazine, and a naphthyl group is bonded at positions 5 to 8 of the 2-naphthyl group substituted with triazine. On the contrary, there is a difference between Compound A and Compound B in that a substituent is substituted at position 1 of the 2-naphthyl group of triazine. In particular, the types of substituents substituted on the 1- and 2-naphthyl groups of triazine in comparative compound B are different from those in the compound of the present invention. Also, comparative compound C differs from the compound of the present invention in that the substituent substituted on 2-naphthyl group is phenyl, not naphthyl.

(197) In order to determine the difference in energy levels of compounds according to the structural differences of these compounds, the energy levels of Comparative Compounds A to C and the similar Compound P-2 of the present invention were measured using the DFT method (B3LYP/6-31g(D)) of the Gaussian program. The measurement results are shown in Tables 7 and 8.

(198) TABLE-US-00008 TABLE 7 comparative comparative comparative P-2 compound A compound B compound C LUMO(eV) 2.000 1.841 1.815 1.979

(199) Referring to Table 7, it can be seen that the compounds of the present invention have lower LUMO energy levels than the comparative compounds.

(200) In the case of the compound of the present invention, it participates in electron transport within the emitting layer as a first host compound, and plays a role in accepting and moving electrons entering from the electron transport layer to the emitting layer. The compound of the present invention, which has a lower LUMO energy level compared to the comparative compounds, exhibits relatively easier electron transfer and thus faster EOD. That is, as the electron mobility of the electron-transport host improves, the charge balance between electrons and holes is well achieved within the emitting layer rather than at the interface, so the efficiency and lifespan appear to be improved.

(202) In particular, in the case of the comparative compound A, which differs only in the substitution position of the substituent from the compound of the present invention, it can be seen that the HOMO energy level increases as shown in Table 8 when the position of the naphthyl substituent substituted on 2-naphthyl group of the triazine is changed from the 5th to 8th positions to the 1st position. That is, as the substitution position of the substituent changes, the hole characteristics of the electron-transport host are strengthened, so that the electron transfer characteristics are relatively lowered compared to the compound of the present invention.

(203) Therefore, when the compound of the present invention is used as an emitting layer material, the transfer of electrons within the molecule is smooth, so that charge balance within the emitting layer is well achieved, and thus the operation, efficiency, and lifespan of the element are improved.

(204) When an emitting layer is composed of multiple host compounds, the characteristics are different depending on the types of the first and second compounds, and it is judged that the driving, efficiency, and lifespan are determined depending on the ease of injection and movement of holes and electrons. Therefore, when the compound of the present invention is used in the emitting layer, it can be expected that the electron mobility of the electron-transport host will improve, the light-emitting region will move toward the interface between the hole transport layer and the emitting layer, and the extent to which holes flowing from the hole transport layer into the emitting layer accumulate will decrease. That is, it appears that the efficiency and lifespan have been improved because the charge balance between electrons and holes within the emitting layer has been well achieved.

(205) From Tables 6 to 8, it can be confirmed that the compound of the present invention, which satisfies all complex elements such as the type of substituent and the substitution position of the substituent, even though it is a compound having a similar configuration, exhibits a remarkable effect in an organic electronic element compared to other comparative compounds, and through this, it can be seen that the compound of the present invention, which satisfies all specific configurations, exhibits a remarkable effect in an organic electronic element compared to other comparative compounds not described in this specification.

(206) 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.
