Organic compound, and electronic element and electronic device using same
-
Paragraph 0150-0152; 0155, (2021/07/14)
The invention relates to an organic compound. The structure of the organic compound is shown as a formula I. When the organic compound is used as a hole adjustment layer material of an electronic element, driving voltage can be reduced, the luminous efficiency of a device can be improved, and the service life of the device can be prolonged.
Nitrogen-containing compound, electronic element, and electronic device
-
Paragraph 0086; 0087; 0091, (2020/06/05)
The invention provides a nitrogen-containing compound, an electronic component and an electronic device, and belongs to the technical field of organic materials. The structure of the nitrogen-containing compound is shown as a chemical formula 1. The nitrogen-containing compound can improve the performance of the electronic component. Ar is shown in the description, and X is selected from O or S; L1 is shown in the description, and in L1, # represents a connection point between phenylene of L1 and N, represents a connection point between phenylene of L1 and a group shown in the description;L2 is shown in the description, in L2, # represents a connection point between the phenylene group of L2 and N, and represents a connection point between the phenylene group of L2 and R4.
Organic compound containing condensed ring structure and organic electroluminescent device
-
Paragraph 0135-0138; 0143-0145, (2020/05/02)
The invention provides an organic compound containing a condensed ring structure as shown in a formula I which is described in the specification. The invention also provides an application of the organic compound in an electroluminescent device. Compared with organic compounds in the prior art, the organic compound containing the condensed ring structure has a narrower half-peak width of an emission peak, so that the organic compound has excellent color purity; when the organic compound containing the condensed ring structure is applied to an AMOLED top emission screen body, higher luminous efficiency can be achieved, and an organic light-emitting device can have lower driving voltage and longer service lifetime.
