     BACKGROUND 
     An organic light emission phenomenon generally refers to a phenomenon converting electrical energy to light energy using an organic material. An organic light emitting device using an organic light emission phenomenon normally has a structure including an anode, a cathode, and an organic material layer therebetween.

     DETAILED DESCRIPTION 
     Hereinafter, the present specification will be described in more detail. 
     One embodiment of the present specification provides a compound represented by Chemical Formula 1. 
     Chemical Formula 1 according to one embodiment of the present specification is a compound in which an N-containing heterocyclic group and a fluoranthene derivative bond at positions of 1,2, positions of 1,3 or positions of 2,3 of naphthalene, and, by being included in an organic material layer of an organic light emitting device, is capable of enhancing efficiency, obtaining a low driving voltage, enhancing lifetime properties, and the like. Specifically, the N-containing heterocyclic group of Chemical Formula 1 is capable of increasing molecular polarity (dipole moment) by having a substituent with an electron-deficient structure, and therefore, electron mobility may be smoothly controlled when manufacturing an organic light emitting device including the compound represented by Chemical Formula 1, and efficiency and lifetime of the organic light emitting device including the compound represented by Chemical Formula 1 may be enhanced. 
     In addition, steric hindrance obtained by the structure of the fluoranthene derivative of Chemical Formula 1 prevents crystallization occurring when forming a film, and has an effect of being very stable even at a high deposition temperature by maintaining high thermal stability. Accordingly, an organic light emitting device including the compound according to one embodiment of the present specification is capable of enhancing efficiency, obtaining a low driving voltage, enhancing lifetime properties, and the like.

     Manufacture of Organic Light Emitting Device 
     Example 1 
     A glass substrate on which indium tin oxide (ITO) was coated as a thin film to a thickness of 100 nm was placed in detergent-dissolved distilled water and ultrasonic cleaned. Herein, a product of Fischer Co. was used as the detergent, and as the distilled water, distilled water filtered twice with a filter manufactured by Millipore Co. was used. After the ITO was cleaned for 30 minutes, ultrasonic cleaning was repeated twice using distilled water for 10 minutes. After the cleaning with distilled water was finished, the substrate was ultrasonic cleaned with solvents of isopropyl alcohol, acetone and methanol, then dried, and then transferred to a plasma cleaner. In addition, the substrate was cleaned for 5 minutes using oxygen plasma, and then transferred to a vacuum deposition apparatus. 
     On the transparent ITO electrode prepared as above, the following Compound HI-A was thermal vacuum deposited to a thickness of 60 nm to form a hole injection layer. 
     On the hole injection layer, the following Compound HAT was vacuum deposited to form a first hole transfer layer having a thickness of 5 nm, and the following Compound HT-A was vacuum deposited on the first hole transfer layer to form a second hole transfer layer having a thickness of 50 nm. 
     Subsequently, Compound BH and Compound BD were vacuum deposited on the second hole transfer layer in a weight ratio of 25:1 to form a light emitting layer having a thickness of 20 nm. 
     On the light emitting layer, [Compound 1-1] and the following Compound LiQ were vacuum deposited in a weight ratio of 1:1 to form an electron injection and transfer layer having a thickness of 35 nm. 
     A cathode was formed by depositing lithium fluoride (LiF) on the electron injection and transfer layer to a thickness of 1 nm and then depositing aluminum to a thickness of 100 nm, and as a result, an organic light emitting device was manufactured. 
     In the above-described process, the deposition rates of the organic materials were maintained at 0.04 nm/sec to 0.09 nm/sec, the deposition rate of the lithium fluoride was maintained at 0.03 nm/sec, and the deposition rate of the aluminum was maintained at 0.2 nm/sec. The degree of vacuum during the deposition was maintained at 1×10 −7  torr to 5×10 −5  torr.

     In Table 1, it was identified that Examples 1 to 30 using Chemical Formula 1 according to one embodiment of the present specification in the electron injection and transfer layer of the organic light emitting device had lower driving voltage, higher efficiency and more superior lifetime properties compared to Comparative Examples 1 to 12. Particularly, it was seen that the organic light emitting devices of Examples 1 to 30 including the compound in which an N-containing heterocyclic group and a fluoranthene derivative bond at positions of 1,2, positions of 1,3 or positions of 2,3 of naphthalene as in Chemical Formula 1 according to one embodiment of the present specification had more superior driving voltage, efficiency and lifetime compared to the organic light emitting devices of Comparative Examples 6 to 12 having substituents bonding at positions other than the positions of 1,2, the positions of 1,3 or the positions of 2,3 of naphthalene since the N-containing heterocyclic group smoothly controlled the electron mobility when manufacturing the organic light emitting device by having a substituent with an electron-deficient structure and thereby increasing molecular polarity (dipole moment). 
     Hereinbefore, preferred embodiments of the present disclosure have been described, however, the present disclosure is not limited thereto, and various modifications may be made within the scope of the claims and the scope of the detailed descriptions, and these also fall within the category of the present disclosure.
