[0003] The present invention relates to novel compounds and organic light-emitting devices comprising the same. Background Art
[0004] Generally speaking, the organic light-emitting phenomenon refers to the phenomenon of converting electrical energy into light energy using organic substances. Organic light-emitting devices using the organic light-emitting phenomenon have wide viewing angles, excellent contrast, fast response time, and excellent brightness, driving voltage, and response speed characteristics, so a lot of research is being carried out.
[0005] An organic light-emitting device generally has a structure including an anode and a cathode and an organic layer located between the anode and the cathode. In order to improve the efficiency and stability of the organic light-emitting device, the organic layer is usually formed by a multilayer structure composed of different substances, for example, a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, an electron injection layer, etc. For such an organic light-emitting device structure, if a voltage is applied between the two electrodes, holes are injected from the anode into the organic layer, and electrons are injected from the cathode into the organic layer. When the injected holes and electrons meet, excitons are formed, and when the excitons transition back to the ground state, light is emitted.
[0006] As for organic substances used for organic light-emitting devices as described above, development of new materials continues to be required.
