Abstract

The present application relates to an organic compound, an electronic element and an electronic apparatus. A structural formula of the organic compound of the present application is represented by Formula I, and when used in an organic electroluminescent device, the organic compound may significantly improve the performance of the device.

First claim

1 . An organic compound having a structure represented by Formula I:

wherein Ar 1 and Ar 2 are each independently selected from a substituted or unsubstituted aryl with 6 to 33 carbon atoms, or a substituted or unsubstituted heteroaryl with 12 to 18 carbon atoms;
substituents of Ar 1 and Ar 2 are each independently selected from deuterium, a fluorine, a cyano, a trialkylsilyl with 3 to 6 carbon atoms, a haloalkyl with 1 to 5 carbon atoms, an alkyl with 1 to 5 carbon atoms, an aryl with 6 to 12 carbon atoms or a heteroaryl with 5 to 12 carbon atoms; optionally, in Ar 1 and Ar 2 , any two adjacent substituents form a substituted or unsubstituted 5-membered to 13-membered ring; and substituents of the 5-membered to 13-membered ring are independently selected from deuterium, a fluorine, a cyano, a trimethylsilyl, a trifluoromethyl, a methyl, an ethyl, an isopropyl or a tert-butyl;
L 1 and L 2 are selected from a single bond, or a substituted or unsubstituted group V, wherein the unsubstituted group V is selected from the following groups:

where the substituted group V has one or two or more substituents, the substituents are independently selected from a methyl, an ethyl, an isopropyl, a tert-butyl or a phenyl, and when the number of the substituents is greater than 1, the substituents are the same or different.

2 . (canceled)

3 . The organic compound of claim 1 , wherein Ar 1 and Ar 2 are each independently selected from a substituted or unsubstituted phenyl, a substituted or unsubstituted naphthyl, a substituted or unsubstituted biphenyl, a substituted or unsubstituted fluorenyl, a substituted or unsubstituted dibenzofuranyl, a substituted or unsubstituted pyridyl, a substituted or unsubstituted dibenzothienyl, a substituted or unsubstituted carbazolyl, a substituted or unsubstituted phenanthryl, or a substituted or unsubstituted triphenylene.

4 . The organic compound of claim 1 , wherein Ar 1 and Ar 2 are each independently selected from a substituted or unsubstituted group W, wherein the unsubstituted group W is selected from the following groups:

and
where the substituted group W has one or two or more substituents, the substituents are independently selected from deuterium, a fluorine, a cyano, a trimethylsilyl, a trifluoromethyl, a methyl, an ethyl, an isopropyl, a tert-butyl, a phenyl, a naphthyl or a biphenyl, and when the number of the substituents is greater than 1, the substituents are the same or different.

5 . The organic compound of claim 1 , wherein Ar 1 and Ar 2 are each independently selected from the following groups:

6 . (canceled)

7 . The organic compound of claim 1 , wherein L 1 and L 2 are each independently selected from a single bond, a substituted or unsubstituted phenylene, a substituted or unsubstituted naphthylene, or a substituted or unsubstituted biphenylene.

8 . (canceled)

9 . The organic compound of claim 1 , wherein the organic compound is selected from the group consisting of the following compounds:
