Claims11
An organic compound having a structure represented by Formula I:
- wherein Ar1 and Ar2 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 Ar1 and Ar2 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 Ar1 and Ar2, 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;
- L1 and L2 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.
