Definitions
- the present application relates to the technical field of organic compounds, and in particular to an organic compound and an organic electroluminescent device and an electronic device comprising the organic compound.
- Such electronic components generally include a cathode and an anode arranged relatively to each other, and a functional layer arranged between the cathode and the anode.
- the functional layer is composed of multiple layers of organic or inorganic film layers, and generally includes an organic light-emitting layer, a hole transport layer located between the organic light-emitting layer and the anode, and an electron transport layer located between the organic light-emitting layer and the cathode.
- an organic electroluminescent device as an example, it generally includes an anode, a hole transport layer, an organic light-emitting layer, an electron transport layer and a cathode stacked in sequence.
- the two electrodes When a voltage is applied to the positive and negative electrodes, the two electrodes generate an electric field. Under the action of the electric field, the electrons on the cathode side move toward the organic light-emitting layer, and the holes on the anode side also move toward the organic light-emitting layer.
- the electrons and holes combine in the organic light-emitting layer to form excitons, and the excitons are in an excited state and release energy outward, thereby causing the organic light-emitting layer to emit light outward.
- the prior art discloses host materials that can be used to prepare organic light-emitting layers in organic electroluminescent devices. However, it is still necessary to continue to develop new materials to further improve the performance of electronic components.
- the purpose of the present application is to provide an organic compound and an organic electroluminescent device and an electronic device containing the organic compound, wherein the organic compound can improve the performance of the organic electroluminescent device and the electronic device, such as reducing the driving voltage of the device and improving the efficiency and life of the device.
- an organic compound wherein the organic compound has a structure as shown in Formula 1:
- ring A is a benzene ring or a naphthalene ring
- X1 is O
- S or X2 is O
- S or and one of X1 and X2 is O or S, and the other is
- L 1 , L 2 and L 3 are the same or different and are independently selected from a single bond, a substituted or unsubstituted arylene group having 6 to 30 carbon atoms, and a substituted or unsubstituted heteroarylene group having 3 to 30 carbon atoms;
- L is selected from a substituted or unsubstituted arylene group having 6 to 30 carbon atoms and a substituted or unsubstituted heteroarylene group having 3 to 30 carbon atoms;
- Ar 1 , Ar 2 and Ar 3 are the same or different and are independently selected from a substituted or unsubstituted aryl group having 6 to 40 carbon atoms and a substituted or unsubstituted heteroaryl group having 3 to 40 carbon atoms;

- compound 4:RH-P:RD was co-evaporated at an evaporation rate ratio of 49%:49%:2% to form a layer with a thickness of of an organic light-emitting layer (EML).
- EML organic light-emitting layer
- compound ET-01 and LiQ are co-evaporated at an evaporation rate ratio of 1:1 to form A thick electron transport layer (ETL) is formed by evaporating Yb on the electron transport layer to form a layer with a thickness of Then, magnesium (Mg) and silver (Ag) were mixed at a deposition rate of 1:9 and vacuum-deposited on the electron injection layer to form a layer with a thickness of cathode.
- ETL electron transport layer
- compound CP-1 is vacuum-evaporated on the cathode to form a layer with a thickness of An organic covering layer is formed, thereby completing the manufacture of a red organic electroluminescent device.
- An organic electroluminescent device was prepared by the same method as in Example 1, except that compound Y in the following Table 8 was used instead of compound 4 in Example 1 when preparing the light-emitting layer.
- An organic electroluminescent device was prepared by the same method as in Example 1, except that compound A, compound B and compound C were used to replace compound 4 in Example 1 when preparing the light-emitting layer.
- the red organic electroluminescent devices prepared in Examples 1 to 37 and Comparative Examples 1 to 3 were subjected to performance tests. Specifically, the IVL performance of the devices was tested under the condition of 10 mA/cm 2 , and the T95 device life was tested under the condition of 20 mA/cm 2. The test results are shown in Table 8.
- the organic compound of the present application is used as an organic electroluminescent device, and compared with Comparative Examples 1 to 3, the current efficiency is at least increased by 9.9%, and the T95 life is at least increased by 11.1%.
