Organic material composition and applications thereof

An organic material composition, wherein the organic material composition comprises at least one compound having a structure represented by Formula 1 and at least one compound having a structure represented by Formula 2:

• wherein, R is selected from hydrogen, deuterium, halogen, a cyano group, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C3-C30 cycloalkyl group, a substituted or unsubstituted C6-C30 aryl group, and a substituted or unsubstituted C3-C30 heteroaryl group;
• R1 is -L1Ar1;
• R2 is -L2Ar2;
• R3 is -L3Ar3;
• R4 is -L4Ar4;
• L1 to L4 are each independently selected from a bond, a substituted or unsubstituted C6-C30 arylene group, and a substituted or unsubstituted C3-C30 heteroarylene group;
• and
• Ar1 to Ar4 are each independently selected from hydrogen, deuterium, halogen, a cyano group, a substituted or unsubstituted C6-C60 arylamino group, a substituted or unsubstituted C3-C60 heteroarylamino group, a substituted or unsubstituted C6-C60 aryl group, and a substituted or unsubstituted C3-C60 heteroaryl group;
• Z1 is selected from N and CLY1ArY1;
• Z2 is selected from N and CLY2ArY2;
• Z3 is selected from N and CLY3ArY3;
• Z4 is selected from N and CLY4ArY4;
• Z5 is selected from N and CLY5ArY5;
• Z6 is selected from N and CLY6ArY6;
• LY1, LY2, LY3, LY4, LY5 and LY6 are each independently selected from a bond, a substituted or unsubstituted C6-C30 arylene group, and a substituted or unsubstituted C3-C30 heteroarylene group;
• ArY1, ArY2, ArY3, ArY4, ArY5 and ArY6 are each independently selected from hydrogen, deuterium, halogen, a cyano group, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C3-C30 cycloalkyl group, a substituted or unsubstituted C6-C60 aryl group, and a substituted or unsubstituted C3-C60 heteroaryl group;
• and
• LY1ArY1, LY2ArY2, LY3ArY3, LY4ArY4, LY5ArY5 and LY6ArY6 are present individually without forming a ring, or any adjacent two of LY1ArY1, LY2ArY2, LY3ArY3, LY4ArY4, LY5ArY5 and LY6ArY6 joined to form a substituted or unsubstituted C6-C30 aromatic ring, or a substituted or unsubstituted C3-C30 heteroaromatic ring.
