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.
Claims12
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, and a substituted or unsubstituted C3-C60 heteroaryl group;
- at least one of Ar1 to Ar4 is a group represented by Formula a:
- X1 is selected from N and CRX1;
- X2 is selected from N and CRX2;
- X3 is selected from N and CRX3;
- X4 is selected from N and CRX4;
- X5 is selected from N and CRX5;
- RX1 to RX5 are each independently selected from hydrogen, deuterium, 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;
- RX1-RX5 are present individually without forming a ring, or any adjacent two of RX1-RX5 joined to form a ring B, and the ring B is a benzene ring;
- Ar10 is selected from a substituted or unsubstituted C6-C60 aryl group, and a substituted or unsubstituted C3-C60 heteroaryl group;
- L10 is selected from a bond, a substituted or unsubstituted C6-C30 arylene group, and a substituted or unsubstituted C3-C30 heteroarylene group;
- R10 to R17 are each independently selected from hydrogen, deuterium, halogen, a cyano group, a substituted or unsubstituted C1-C30 alkyl group, a C1-C30 alkyl group in which one or more methylene groups are independently substituted by —O— and/or —S— in a manner that O atom and/or S atom are not adjacent to each other, a substituted or unsubstituted C2-C30 alkenyl group, a C2-C30 alkenyl group in which one or more methylene groups are independently substituted by —O— and/or —S— in a manner that O atom and/or S atom are not adjacent to each other, a substituted or unsubstituted C7-C30 arylalkyl group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C3-C30 heteroaryl group, a substituted or unsubstituted C4-C30 heteroarylalkyl group, a substituted or unsubstituted C3-C30 cycloalkyl group, a substituted or unsubstituted C3-C30 heterocycloalkyl group, a substituted or unsubstituted C3-C30 cycloalkenyl group, a substituted or unsubstituted C1-C30 alkoxy group, and a substituted or unsubstituted C6-C30 aryloxy group;
- R10 to R17 are present individually without forming a ring, or any adjacent two to four of R10 to R17 joined to form a ring A, and the ring A is a substituted or unsubstituted C6-C30 aromatic ring, or a substituted or unsubstituted C3-C30 heteroaromatic ring.
