Ar 1 , Ar 2 , Ar 3 , and Ar 4 are identical or different, and are each independently selected from a substituted or unsubstituted phenyl, a substituted or unsubstituted naphthyl, a substituted or unsubstituted biphenyl, a substituted or unsubstituted terphenyl, a substituted or unsubstituted fluorenyl, a substituted or unsubstituted dibenzofuranyl, a substituted or unsubstituted dibenzothiophenyl, or a group shown in Formula 2; and at least one of Ar 1 and Ar 3 is selected from the group shown in Formula 2;

wherein n is 1 or 2;
substituents of Ar 1 , Ar 2 , Ar 3 , and Ar 4 are identical or different, and are each independently selected from deuterium, methyl, ethyl, isopropyl, tert-butyl or phenyl.

2. The organic compound according to claim 1 , wherein Ar 1 and Ar 3 are identical or different, and are each independently selected from the group consisting of the following groups:

and at least one of Ar 1 and Ar 3 is selected from

Ar 2 and Ar 4 are identical or different, and are each independently selected from the group consisting of the following groups:

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

4. An electronic component, comprising an anode, a cathode, and a functional layer disposed between the anode and the cathode, wherein the functional layer comprises the organic compound according to claim 1 .

5. The electronic component according to claim 4 , wherein the functional layer comprises a hole transport layer comprising the organic compound.

6. The electronic component according to claim 4 , wherein the electronic component is an organic electroluminescent device or a photoelectric conversion device.

7. The electronic component according to claim 6 , wherein the organic electroluminescent device is a blue light organic electroluminescent device.

8. An electronic apparatus, comprising the electronic component according to claim 4 .
