Abstract
The present invention provides an organic material composition and applications thereof. By the combination of the compounds comprised in the organic material composition, the organic material composition makes the element have a lower driving voltage, a higher current efficiency and a longer service life.
Claims16
An organic material composition, characterized in that 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 aryl group, and a substituted or unsubstituted C3-C60 heteroaryl group;
- ArW1, ArW2 and ArW3 are each independently selected from hydrogen, deuterium, a substituted or unsubstituted C6-C60 aryl group, and a substituted or unsubstituted C3-C60 heteroaryl group;
- LW1, LW2 and LW3 are each independently selected from a bond, a substituted or unsubstituted C6-C30 arylene group, and a substituted or unsubstituted C3-C30 heteroarylene group.
