[0192] As can be seen from the results in Table 4 to Table 7, when a green organic electroluminescent device is manufactured using the material for an organic electroluminescent device of the present invention as a material for the emitting-auxiliary layer, the driving voltage, luminous efficiency, and lifespan of the organic electroluminescent device can be improved compared to the comparative examples using Comparative Compounds A to Comparative Compounds D, which have similar basic structures to the compound of the present invention.
[0193] Comparative Compounds A to Comparative Compounds D are similar to the compounds of the present invention in that fluorine or dibenzofuran, or dibenzothiophene is substituted in the tertiary amine compound, but the compounds of the present invention differ from comparative compounds in that at least one fluorene and at least one dibenzofuran or dibenzothiophene are substituted in the molecule.
[0194] In the case of Comparative Compound A and Comparative Compound B, which are tertiary amine compounds substituted with dibenzofuran or dibenzothiophene, because they contain hetero elements, their stability against electrons increases and they have a longer lifespan than Comparative Compound C and Comparative Compound D, but they require a high driving voltage. In the case of Comparative Compound C and Comparative Compound D, which are fluorene-substituted tertiary amine compounds, they exhibit a low driving voltage, but the 9th position of the fluorene moiety is vulnerable to electric charges, resulting in a relatively short lifespan.
[0195] However, it is believed that unlike the comparative compounds, the compound of the present invention has at least one fluorene and at least one dibenzofuran or dibenzothiophene substituted in the molecule, so that not only can the advantages of each moiety be utilized, but it has an energy level suitable for the emitting-auxiliary layer, which affects the performance of the entire element.
[0196] Table 4 shows examples that substituents are each introduced into at least one fluorene and at least one dibenzofuran or dibenzothiophene among the compounds of the present invention.
[0197] In more detail, when substituents are introduced to fluorene, dibenzofuran, and dibenzothiophene, due to steric hindrance of molecules, a high T1 energy level is formed, and pi-pi stacking between molecules is suppressed, and due to the substituent, the molecular structure shields the amine moiety, and the electrons in the molecule are separated toward the amine moiety, causing the charge to move relatively quickly, therefore the charge balance of the entire element is improved, and although the planarity of the molecules decreases during device deposition, but the Tg value decreases, making it possible to manufacture elements even at relatively low temperatures during deposition.
[0198] Also, as the distance between molecules increases due to steric hindrance, the effect of lowering the crystallinity of the thin film, that is, creating an amorphous state, is believed to improve hole mobility and increase the stability of the compound itself.
[0199] Moreover, by introducing additional substituents to fluorene, dibenzofuran, and dibenzothiophene, conjugation increases, the electron cloud of HOMO expands, and the HOMO-LUMO band gap also increases, thereby increasing hole injection and hole transport characteristics, allowing holes to be transferred from the hole transport layer to the emitting layer, and having an energy level suitable as an emitting-auxiliary layer that must block electrons coming from the emitting layer.
[0200] Table 5 is a manufacturing evaluation of an element conducted to confirm the characteristics of the compounds of the present invention when a substituent is introduced into one of fluorene, dibenzofuran, or dibenzothiophene. In the manufacturing evaluation of the element, the better results were obtained in Examples 29 to 53 using the compounds of the present invention than in Comparative Examples 5 to 8.
[0201] In more detail, among the compounds of the present invention, when an amine group was substituted at position 1 of dibenzofuran, generally better device results were obtained than when an amine group was substituted at other positions. Among them, when a substituent was introduced at position 7 or 8 of dibenzofuran, significantly excellent measurement results of the element were obtained.
[0202] When additional substituents are introduced, the steric hindrance of the structure increases as described above, and when an amine group is substituted at position 1 of dibenzofuran, the effect of steric hindrance is greater when an additional substituent is introduced at position 8 than when an additional substituent is introduced at position 7 of dibenzofuran.
[0203] However, when the 7th position of dibenzofuran is substituted with an alkyl group, such as tert-butyl or adamantyl group, which have very large bulkiness among alkyl groups, steric hindrance similar to that of substitution at the 8th position occurs, resulting in excellent device results.
[0204] When an alkyl group, which can greatly increase steric hindrance, is substituted, mobility decreases due to steric hindrance, but the effect of suppressing the formation of crystalline substances is significant, so it is believed to have an advantageous effect during deposition of elements.
[0205] It is judged that when an amine group is introduced at position 1 of dibenzofuran and a substituent is introduced at position 8 of dibenzofuran, steric hindrance characteristics are maximized compared to when an amine group or substituent is introduced at any other position of dibenzofuran, so HOMO is formed at a high level and mobility is also improved, resulting in low voltage characteristics. Also, it can be seen that by protecting the active site by introducing an additional substituent at position 8, the active site of dibenzofuran, (a position with high reactivity due to low electron density), the chemical stability of the structure itself is increased and the lifespan is also improved.
[0206] Even in the case of dibenzothiophene with an amine group and substituent introduced at the same substitution position, excellent results of elements were obtained compared to the comparative compound. However, overall, better results were obtained in a structure substituted with dibenzofuran, which has relatively greater structural stability including a more electronegative O atom.
[0207] Even in the case of fluorene, different results were obtained for each substitution position. In particular, even in the case of a structure in which an amine group was substituted at position 2, better results were obtained than when an amine group was substituted at other positions. it is believed that this is because, for fluorene, position 2 is the active site, so when an amine group is substituted in that region, a high HOMO is formed, mobility is also improved, and has low voltage characteristics.
[0208] In the case of fluorene, when additional substituents other than amine groups are introduced, conjugation is prolonged as described above, so there is an advantage in terms of lifespan, but mobility appears to decrease and driving voltage increases.
[0209] That is, among the compounds of the present invention, it can be confirmed that high efficiency, long lifespan, and low voltage characteristics are exhibited in the structure in which 1-dibenzofuran and 2-fluorene are substituted with a substituent introduced at the 7th or 8th position. This is because 2-fluorene compensates for the relatively poor mobility of dibenzofuran, and 1-dibenzofuran, which has a substituent introduced at position 7 or 8, which has a long-life structure, compensates for the relatively poor lifespan characteristics of 2-fluorene, creating a synergistic effect.
[0210] The examples shown in Tables 4 and 5 are evaluation examples of elements composed of only one emitting-auxiliary layer, and the examples shown in Tables 6 and 7 are evaluation examples of elements composed of 2 emitting-auxiliary layers.
[0211] PA-1 used in Tables 5 and 6 is a fluorene-based compound generally used in an emitting-auxiliary layer, and it was confirmed that when manufacturing an element with 2 emitting-auxiliary layers using PA-1, comparative compounds, and compounds of the present invention, the overall performance was improved compared to an element consisting of only one emitting-auxiliary layer made of the same material.
[0212] In the case, when 2 emitting-auxiliary layers exist, different HOMO-LUMO energy levels are formed depending on the material applied to each emitting-auxiliary layer, by appropriately controlling the HOMO-LUMO energy levels of the first and second emitting-auxiliary layers, the interaction with the emitting layer (transfer of holes to the emitting layer and blocking electrons from the emitting layer) can be controlled.
[0213] In the case of the first emitting-auxiliary layer, hole injection from the hole transport layer to the emitting-auxiliary layer must be performed well, and in the case of the second emitting-auxiliary layer, hole injection from the emitting-auxiliary layer to the emitting layer must be performed better, and it is judged that more appropriate hole injection is achieved when the compound of the present invention is applied to the first and second emitting-auxiliary layers than the comparative compound.
[0214] In particular, among the compounds of the present invention, as mentioned above, it was confirmed that excellent results are obtained when compounds with additional substituents introduced into fluorene, and dibenzofuran, or dibenzothiophene are applied as the first or second emitting-auxiliary layer.
[0215] When either Ar.sup.1 or Ar.sup.2 is hydrogen, the structure with a substituent in dibenzofuran showed excellent characteristics, and among the compounds of the present invention, in the case of a structure containing dibenzofuran substituted with an alkyl group with high steric hindrance at position 7 and an amine group at position 1, when used in the first emitting-auxiliary layer, as described above, since mobility is relatively low and hole mobility can be effectively controlled, the efficiency of the element can be greatly increased. In the case of a structure in which an additional substituent is introduced at position 8 and the amine group contains dibenzofuran at position 1, the HOMO-LUMO band gap is formed wide in the second emitting-auxiliary layer, so not only the hole injection characteristics but also overall performance of the element is significantly improved by effectively blocking electrons from the emitting layer.
[0216] Therefore, the compound of the present invention, which satisfies all of the relevant compositions, showed significant effects in terms of drive, efficiency, and lifespan of element data compared to comparative compounds, and it suggests that even if the basic molecular structure is similar to Comparative Compound A to Comparative Compound D and the compound of the present invention, the properties of the compound, such as hole characteristics, light efficiency characteristics, energy level, hole injection and mobility characteristics, charge balance between holes and electrons, volume density, and intermolecular distance, may vary depending on the substitution position and composition of the substituents, and also rather than one configuration affecting the results of the entire element, the performance of the element may vary due to complex factors.
[0217] In the case of an emitting-auxiliary layer, it is necessary to understand the interrelationship between the hole transport layer and the emitting layer (host), so even if a similar core is used, it is very difficult even for a person skilled in the art to infer the characteristics of the emitting-auxiliary layer using the compound of the present invention.
[0218] Additionally, in the above-described device manufacturing evaluation results, the characteristics of elements were explained by applying the compound of the present invention only to the emitting-auxiliary layer, but the compound of the present invention can be applied to the hole transport layer or applied to both the hole transport layer and the emitting-auxiliary layer.
