Compound and organic light emitting element comprising same

#This application is a National Stage Application of International Application No. PCT/KR2018/016650 filed on Dec. 26, 2018, which claims priority to and the benefit of Korean Patent Application No. 10-2017-0179561, filed with the Korean Intellectual Property Office on Dec. 26, 2017, the entire contents of which are incorporated herein by reference.

#The present specification relates to a compound and an organic light emitting device including the same.

#An organic light emitting device has a configuration in which an organic thin film is disposed between two electrodes. Upon application of a voltage to such an organic light emitting device with a configuration, holes and electrons injected from two electrodes are combined and paired in an organic thin film. When such electron-pair pairs are decayed, light is emitted. The organic thin film can have a single or multiple layer structure, if necessary.

#FIG. 1 illustrates an example of an organic light emitting device in which a substrate 1, an anode 2, a light emitting layer 3 and a cathode 4 are sequentially laminated;

#FIG. 2 illustrates an organic light emitting device in which a substrate 1, an anode 2, a hole injection layer 5, a hole transport layer 6, a light emitting layer 3, an electron transport layer 7 and a cathode 4 are sequentially laminated; and

#FIG. 3 illustrates an organic light emitting device in which a substrate 1, an anode 2, a hole injection layer 5, a hole transport layer 6, an electron blocking layer 8, a light emitting layer 3, an electron injection and transport layer 9 and a cathode 4 are sequentially laminated. 1: Substrate 2: Anode 3: Light emitting layer 4: Cathode 5: Hole injection layer 6: Hole transport layer 7: Electron transport layer 8: Electronic blocking layer 9: Electron injection and transport layer

#Hereinafter, the present specification will be described in more detail.

#An embodiment of the present specification provides the compound of Chemical Formula 1 above.

#In the present specification, compounds having various energy bandgaps can be synthesized by introducing various substituents into the core structure as described above. Typically, it is easy to control the energy band gap by introducing a substituent into a core structure having a large energy band gap. On the other hand, when a core structure has a small energy band gap, it is difficult to control the energy band gap by introduction of a substituent. In addition, in the present specification, the HOMO and LUMO energy levels of the compound can be controlled by introducing various substituents into the core structure as described above.
