Abstract

The present application belongs to the field of organic materials, and relates to an organic compound, and an electronic element and an electronic device using same. The organic compound has a structure as represented by Formula I, and the organic compound can significantly improve the performance of an organic electroluminescent device when applied to the device.

First claim

What is claimed is:

1. An organic compound having a structure as shown in Formula I:

wherein R 1 and R 2 are the same or different, and are each independently selected from hydrogen, deuterium, a methyl or a phenyl;
n is selected from 1 or 2;
X is selected from C(R 5 R 6 ), O or S;
R 5 and R 6 are the same or different, and are each independently selected from a methyl, an ethyl, an isopropyl, a tert-butyl, a phenyl, a naphthyl, or a biphenyl; and optionally, R 5 and R 6 are connected to each other to form a cyclopentane, a cyclohexane, a norbornane or a fluorene ring;
L is selected from a single bond, a substituted or unsubstituted phenylene, a substituted or unsubstituted biphenylene, or a substituted or unsubstituted naphthylene;
L 1 and L 2 are the same or different, and are each independently selected from a single bond, a substituted or unsubstituted phenylene, a substituted or unsubstituted biphenylene, a substituted or unsubstituted naphthylene, a substituted or unsubstituted dibenzofurylene, or a substituted or unsubstituted dibenzothienylene;
substituents of L, L 1 and L 2 are the same or different, and are each independently selected from deuterium, a fluorine, a cyano, an alkyl with 1 to 5 carbon atoms, a trimethylsilyl, or a phenyl;
Ar 1 and Ar 2 are the same or different, and are each independently selected from a substituted or unsubstituted group V, or a substituted or unsubstituted group W;
wherein the unsubstituted group V is selected from the group consisting of the following groups:

wherein represents a chemical bond; the substituted group V has one or two or more substituents, the substituents are each independently selected from deuterium, a fluorine, a cyano, a methyl, an ethyl, an isopropyl, a tert-butyl, a trifluoromethyl, a trimethylsilyl, a phenyl, a naphthyl, a cyclopentyl, a cyclohexyl, or an adamantyl; and when the number of the substituents is greater than 1, the substituents are the same or different;
the unsubstituted group W is selected from the group consisting of the following groups:

wherein represents a chemical bond: the substituted group W has one or two or more substituents, the substituents are independently selected from deuterium, a fluorine, a cyano, a methyl, an ethyl, an isopropyl, or a tert-butyl; and when the number of the substituents is greater than 1, the substituents are the same or different;
R 3 and R 4 are the same or different, and are each independently selected from deuterium, a cyano, a fluorine, a methyl, an ethyl, an isopropyl, a tert-butyl, a phenyl, a trimethylsilyl, or a trifluoromethyl;
n 1 represents the number of R 3 , and is selected from 0, 1 or 2, and when n 1 is 2, each R 3 is the same or different; and n 2 represents the number of R 4 , and is selected from 0, 1, 2 or 3, and when n 2 is greater than 1, each R 4 is the same or different.

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

3. The organic compound of claim 1 , wherein the structure of the organic compound is selected from the group consisting of the following structural formulas:

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