Abstract
Description
[Technical field]
[0001] The present invention relates to an amine-based compound and an organic light-emitting device containing the same. [Background technology]
[0002] An organic light emitting device is a self-emitting device, which is different from conventional devices. Compared to conventional LCDs, LCDs not only have a wider viewing angle and better contrast, but also a shorter response time, and are excellent in terms of luminance, driving voltage and response speed, and can be made multicolor.
[0003] An organic light emitting device may have a structure in which a first electrode is disposed on a substrate, and a hole transport region, a light emitting layer, an electron transport region, and a second electrode are sequentially disposed on the first electrode. Holes injected from the first electrode move to the light emitting layer via the hole transport region, and electrons injected from the second electrode move to the light emitting layer via the electron transport region. Carriers such as holes and electrons recombine in the light emitting layer region to generate excitons. When the excitons transition from an excited state to a ground state, When this happens, light is emitted. [Prior art documents] [Patent documents]

[0072] In one example, the amine compound represented by Chemical Formula 1 is selected from the following compounds 1 to 144, but is not limited thereto. [ka] TIFF0007617172000021.tif122118JPEG0007617172000022.jpg119117 TIFF0007617172000023.tif120118 JPEG0007617172000024.jpg121117 JPEG0007617172000025.jpg124119 TIFF0007617172000026.tif120118 JPEG0007617172000027.jpg126116 JPEG0007617172000028.jpg134119 JPEG0007617172000029.jpg113115 JPEG0007617172000030.jpg113119 JPEG0007617172000031.jpg114114
[0073] The amine compound represented by Chemical Formula 1 is formed by further condensing benzene at a specific position of fluorene, and substituting a substituent having a ring structure at a specific position of fluorene, The orbital non-uniform distribution facilitates hole hopping, and therefore the amine compound has high charge mobility, allowing an organic light emitting device including the amine compound to be driven with low power.
[0074] In addition, the amine compound has a lower highest occupied molecular orbital (HOMO) energy level than a compound containing two or more amino groups because it contains one amino group in the molecule, and therefore has an energy level optimized for hole transport. Therefore, an electronic device using the amine compound, such as an organic light-emitting device, can achieve low driving voltage, high efficiency, and long life.
[0075] Those skilled in the art will be able to recognize how to synthesize the amine compound represented by Chemical Formula 1 by referring to the examples described below.
[0076] At least one of the amine-based compounds represented by Chemical Formula 1 is used between a pair of electrodes of an organic light-emitting device. For example, the amine-based compound may be included in at least one of a hole transport region, an electron transport region, and an emission layer. Alternatively, the amine-based compound represented by Chemical Formula 1 may be used as a capping layer material located outside a pair of electrodes of an organic light-emitting device.
[0077] Accordingly, there is provided an organic light emitting device comprising a first electrode, a second electrode facing the first electrode, and an organic layer disposed between the first electrode and the second electrode and including a light emitting layer, wherein the organic layer comprises one or more amine-based compounds represented by Chemical Formula 1.
[0078] In this specification, "(the organic layer) contains one or more amine compounds" can also be interpreted as "(the organic layer) may contain one amine compound belonging to the category of Chemical Formula 1, or two or more different amine compounds belonging to the category of Chemical Formula 1."
[0079] For example, the organic layer may contain only compound 1 as the amine-based compound. In this case, compound 1 may be contained in the light-emitting layer of the organic light-emitting device. Alternatively, the organic layer may contain compound 1 and compound 2 as the amine-based compounds.
