(40) FIGS. 1 to 3 are exemplary views of an organic electronic element according to an embodiment of the present invention.

(41) Referring to FIG. 1, an organic electronic element (100) according to an embodiment of the present invention comprises a first electrode (110), a second electrode (170) formed on a substrate (not shown), and an organic layer formed between the first electrode (110) and the second electrode (170).

(42) The first electrode (110) may be an anode, the second electrode (170) may be a cathode, and in the case of an inverted type, the first electrode may be a cathode and the second electrode may be an anode.

(43) The organic material layer may include a hole injection layer (120), a hole transport layer (130), an emitting layer (140), an electron transport layer (150), and an electron injection layer (160). Specifically, a hole injection layer (120), a hole transport layer (130), an emitting layer (140), an electron transport layer (150), and an electron injection layer (160) may be sequentially formed on the first electrode (110).

(44) Preferably, a light efficiency enhancing layer (180) may be formed on at least one surface of the first electrode (110) and the second electrode (170), the surface being opposite to the organic material layer, and when the light efficiency enhancing layer (180) is formed, the light efficiency of the organic electronic element may be improved.

(45) For example, the light efficiency enhancing layer (180) may be formed on the second electrode (170), and in the case of a top emission organic light emitting device, the light efficiency enhancing layer (180) is formed, thereby reducing optical energy loss due to surface plasmon polaritons (SPPs) in the second electrode (170), and in the case of a bottom emission organic light emitting device, the light efficiency enhancing layer (180) may function as a buffer for the second electrode (170).

(46) A buffer layer (210) or an emitting auxiliary layer (220) may be further formed between the hole transport layer (130) and the emitting layer (140), which will be described with reference to FIG. 2.

(47) Referring to FIG. 2, an organic electric device (200) according to another embodiment of the present invention includes a hole injection layer (120), a hole transport layer (130), a buffer layer (210), an emitting auxiliary layer (220), an emitting layer (140), an electron transport layer (150), an electron injection layer (160), a second electrode (170), sequentially formed on the first electrode (110), and a light efficiency enhancing layer (180) formed on the second electrode.

(48) Although not shown in FIG. 2, an electron transport auxiliary layer may be further formed between the emitting layer (140) and the electron transport layer (150).

(49) Also, according to another embodiment of the present invention, the organic material layer may have a plurality of stacks including a hole transport layer, an emitting layer and an electron transport layer. This will be described with reference to FIG. 3.

(50) Referring to FIG. 3, in the organic electronic element (300) according to another embodiment of the present invention, 2 or more sets of stacks (ST1 and ST2) made of a multi-layered organic material layer may be formed between the first electrode (110) and the second electrode (170), and a charge generation layer (CGL) may be formed between the stacks of organic material layers.

(51) Specifically, the organic electronic element according to an embodiment of the present invention may include a first electrode (110), a first stack (ST1), a charge generation layer (CGL), a second stack (ST2), and a second electrode (170) and a light efficiency enhancing layer (180).

(52) The first stack (ST1) is an organic material layer formed on the first electrode (110) and may include a first hole injection layer (320), a first hole transport layer (330), a first emitting layer (340), and a first electron transport layer (350), and the second stack (ST2) may include a second hole injection layer (420), a second hole transport layer (430), a second emitting layer (440), and a second electron transport layer (450). As described above, the first stack and the second stack may be organic material layers having the same laminated structure, but may be organic material layers having different laminated structures.

(53) A charge generation layer (CGL) may be formed between the first stack (ST1) and the second stack (ST2). The charge generation layer (CGL) may include a first charge generation layer (360) and a second charge generation layer (361). The charge generation layer (CGL) is formed between the first emitting layer (340) and the second emitting layer (440) to increase the current efficiency generated in each emitting layer and smoothly distribute charge.

(54) When a plurality of emitting layers are formed by the multilayer stack structure method as shown in FIG. 3, an organic electronic element that emits white light by a mixing effect of light emitted from each emitting layer can be manufactured, as well as an organic electronic element that emits light of various colors.

(55) The compounds represented by Formula 1, Formula 4 and 5 of the present invention may be used as a material for a hole injection layer (120, 320, 420), a hole transport layer (130, 330, 430), a buffer layer (210), an emitting auxiliary layer (220), and an electron transport layer (150, 350, 450), the electron injection layer (160), the emitting layer (140, 340, 440), or the light efficiency enhancing layer (180), but preferably, as a host of the emitting layers (140, 340, 440).

(56) Otherwise, even if the same or similar core is used, the band gap, the electrical characteristics, the interface characteristics, and the like may vary depending on which substituent is bonded at which position, therefore it is necessary to study the selection of the core and the combination of sub-substituents bonded thereto, and in particular, when the optimal combination of energy levels and T1 values of each organic material layer and unique properties of materials (mobility, interfacial characteristics, etc.) is achieved, a long lifespan and high efficiency can be achieved at the same time.

(57) The organic light emitting device according to an embodiment of the present invention may be manufactured using various deposition methods. It can be manufactured using a vapor deposition method such as PVD or CVD. For example, an anode (110) is formed by depositing a metal or a conductive metal oxide or an alloy thereof on a substrate, and after forming an organic material layer including the hole injection layer(120), the hole transport layer(130), the emitting layer(140), the electron transport layer(150) and the electron injection layer(160) thereon, the organic electroluminescent device according to an embodiment of the present invention can be manufactured by depositing a material that can be used as a cathode (170) thereon. Also, an emitting auxiliary layer (220) may be further formed between the hole transport layer(130) and the emitting layer(140), and an electron transport auxiliary layer (not shown) may be further formed between the emitting layer(140) and the electron transport layer (150), and as described above, may be formed in a stack structure.

(58) Also, the organic material layer may be manufactured with a smaller number of layers by using various polymer materials and not by a deposition method, but by a solution process or a solvent process, such as a spin coating process, a nozzle printing process, an inkjet printing process, a slot coating process, a dip coating process or a roll-to-roll process, doctor blading process, screen printing process, or a thermal transfer method, etc. Since the organic material layer according to the present invention can be formed by various methods, the scope of the present invention is not limited by the forming method.

(59) In addition, the organic electronic element according to an embodiment of the present invention may be selected from the group consisting of an organic electroluminescent device, an organic solar cell, an organic photoreceptor, an organic transistor, a monochromatic lighting device, and a quantum dot display device.

(60) Another embodiment of the present invention may comprise an electronic device comprising a display device including the organic electronic element of the present invention; and a control unit for driving the display device. At this time, the electronic device may be a current or future wired/wireless communication terminal, and covers all kinds of electronic devices including a mobile communication terminal such as a cellular phone, a personal digital assistant (PDA), an electronic dictionary, a point-to-multipoint (PMP), a remote controller, a navigation unit, a game player, various kinds of TVs, and various kinds of computers.

(286) As can be seen from the results of Table 6, when a red organic light emitting device was manufactured by using the material for an organic light emitting device of the present invention as a host material of the emitting layer, the driving voltage, luminous efficiency and lifespan of the organic light emitting device can be improved compared to Comparative Example using Comparative Compound A or Comparative Compound B having a similar basic skeleton to the compound of the present invention.

(287) Comparative Compound A and Comparative Compound B are similar to the compounds of the present invention in that triazines are substituted with dibenzofuran or dibenzothiophene and groups containing the skeleton of phenyl-phenyl-naphthyl, but in the case of Comparative Compound A, an aryl group is further substituted on the phenyl-phenyl-naphthyl skeleton, and in the case of Comparative Compound B, the substitution position of dibenzofuran or dibenzothiophene is different from that of the compound of the present invention.

(288) Comparing the compound P-1 of the present invention and Comparative compound A in terms of structure, Comparative Compound A has a lower packing density than the compound of the present invention during device deposition as additional aryl groups are substituted on the phenyl-phenyl-naphthyl skeleton, therefore when manufacturing a device, the distance between compounds becomes longer, so the mobility of holes and electrons is relatively lowered. As a result, energy transfer from the host to the dopant is not easily performed, which seems to affect device performance.

(289) Next, although the types of substituents are similar, in order to confirm the energy level of the compound according to the substitution position of the substituent, the electronic energy of Comparative Compound B and Compound P-1 of the present invention having a high similarity thereto was measured using the DFT method (B3LYP/6-31 g(D)) of a Gaussian program, and the measurement data are shown in Table 7.

(290) TABLE-US-00008 TABLE 7 Comparative P-1 compound B T1 (eV) 2.5844 2.5851 S1 (eV) 3.0990 3.2156 ST(eV) 0.5146 0.6305

(291) As can be seen from the results of Table 7, although the elements constituting the substituents are similar, it can be confirmed that the physical properties of the molecule change remarkably depending on the position in which the constituents are substituted.

(292) More specifically, since the compound P-1 of the present invention has a smaller ST (eV) value than the comparative compound B, Compound P-1 of the present invention is more easily transferred from the host to the dopant than the comparative compound B, so that the luminous efficiency of the device is increased, and it was confirmed that the lifespan also significantly increased by well transitioning the unstable excited state energy.

(293) Additionally, to confirm the change in Dihedral angle according to the substitution position of the substituent, Dihedral angle of Comparative Compound B and Compound P-1 of the present invention having high similarity thereto was measured through MM2 Minimize energy calculation of Perkinelmer's Chem3D program, the measurement data are shown in FIGS. 5 and 6.

(294) As can be seen from FIGS. 5 and 6, Dihedral angle values between triazine and dibenzofuran in Compound P-1 of the present invention and Comparative Compound B are 10.4 and 0, respectively. More specifically, Comparative Compound B, which has a very high planar structure, is a compound with a crystalline structure and has a Tc, that is, a crystallization temperature, causing problems such as clogging of the mask and material accumulation during the device deposition process. On the contrary, the compound P-1 of the present invention has an amorphous structure and does not cause the above-mentioned problems, so device fabrication is smooth, and this difference affects device performance.

(295) Among the examples of the present invention, in the case of a structure in which deuterium is substituted at the R.sup.4 and R.sup.5 positions of Formula 1, it can be confirmed that the lifespan is significantly increased compared to the structure in which deuterium is substituted at other R.sup.1 to R.sup.3. In this way, the reason why the lifespan of the device is maximized is that as the part with relatively weak carbon-hydrogen bond dissociation energy is replaced by deuterium, molecular hardcore volume is reduced, as a result, the electrical polarizability is reduced and the stability of the structure itself is greatly increased.

(296) To interpret the above results, the bond dissociation energy E (hereinafter referred to as BDE, unit: eV) of the compound P-1 of the present invention in the anion state was measured using molecular simulation (Schrodinger Materials Science Suite 4.9.128), and the result is shown in FIG. 7.

(297) As can be seen through FIG. 7, since the BDE value of the triazine-substituted dibenzofuran moiety is relatively smaller than the BDE value of other parts, when deuterium is substituted in the dibenzofuran moiety, as described above, the stability of the structure itself is maximized compared to when deuterium is substituted at other positions.

(298) That is, as can be seen from the results of Tables 6, 7, and FIGS. 5 to 7, even if the compound has a similar composition, it can be seen that the compound of the present invention, which satisfies all complex factors such as the type of specific substituent and the specific substitution position of the substituent, exhibits a remarkable effect compared to other comparative compounds in organic electronic elements. Through this, it can be seen that the compound of the present invention exhibits a remarkable effect in organic electronic elements compared to other compounds having similar structures not described herein.

(299) In other words, these results suggests that even for compounds with similar molecular components, the properties of compounds such as hole properties, light efficiency properties, energy level, hole injection and mobility properties of molecules, charge balance between holes and electrons, volume density and distance between molecules, etc. can vary significantly to the extent that it is difficult to predict, depending on the type and position of the substituent to be substituted, and also the performance of the device may vary due to complex factors, rather than one configuration affecting the overall result of the device.
