Description

Technical Field

[0001] The present invention relates to a condensed ring compound and an organic light-emitting element comprising the same. Background Art

[0002] Organic light emitting devices are self-luminous devices that have a wider viewing angle and better contrast than existing devices, and also have a shorter response time, better brightness characteristics, driving voltage characteristics, and response speed characteristics, and can achieve multi-colorization.

[0003] The organic light-emitting element may have the following structure: a first electrode is arranged on the upper part of the substrate, and a hole transport region, a light-emitting layer, an electron transport region, and a second electrode are sequentially formed on the upper part of the first electrode. Holes injected from the first electrode may move to the light-emitting layer through the hole transport region, and electrons injected from the second electrode may move to the light-emitting layer through the electron transport region. Carriers such as holes and electrons are recombined in the light-emitting layer region to generate excitons. The excitons are transformed from an excited state to a ground state to generate light.

[0159]

[0160] The condensed ring compound represented by the Chemical Formula 1 has a wide plate structure including two boron atoms.

[0161] The chemical formula 1 has a skeleton of a wider plate structure including two boron atoms, whereby multiple resonance is further activated by the wider plate structure having a condensed ring, so that HOMO and LUMO can be separated at the atomic level, thereby showing a smaller E STValue and TADF characteristics. The structure of the present invention contains multiple N, O, S atoms and two B atoms and shows the effect of multiple donors and acceptors, thereby increasing the HOMO / LUMO separation effect. Due to the flat and wide structure, the delocalization of electrons in the molecule is amplified, and the polarizability becomes higher, which further increases the f value, so it can be used as a high-efficiency delayed fluorescence luminescent material. In addition, since the main chain has a substituent condensed into a heterocyclic ring, the number of freely rotating CN bonds is reduced compared to the uncondensed substituent, so it can have the effect of making the molecule more rigid in terms of molecular binding energy (BDE), and because it is rich in electrons, it can also have the effect of compensating for the chemical instability that may become fragile due to the characteristics of the electron-deficient boron atom.

[0162] Therefore, an electronic element, for example, an organic light emitting element, using the condensed ring compound represented by Chemical Formula 1 may have low driving voltage, high maximum quantum efficiency, high efficiency, and long lifespan.

Alternatively, the organic layer may include the compound 1 and the compound 2 as the condensed ring compound. In this case, the compound 1 and the compound 2 may be present in the same layer (for example, both the compound 1 and the compound 2 may be present in the light-emitting layer), or in different layers from each other (for example, the compound 1 is present in the light-emitting layer, and the compound 2 is present in the electron transport layer).

[0434] The quantum dots are particles having a crystalline structure with a size of several nanometers to several tens of nanometers, and are composed of hundreds to thousands of atoms.

Accordingly, when light with a wavelength having an energy greater than the band gap of the quantum dots is irradiated to the quantum dots, the quantum dots absorb the light and become excited, and drop to the ground state while emitting light of a specific wavelength. At this time, the wavelength of the emitted light has a value equivalent to the band gap.
