Abstract
The present disclosure provides a compound having a formula (I): where A represents a nitrogen-containing heteroaromatic ring substituent; and L is one or more selected from a single bond, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C3-C8 cycloalkyl, substituted or unsubstituted C1-C8 alkoxy, substituted or unsubstituted C3-C8 heterocyclyl, substituted or unsubstituted C6-C40 aryl, and substituted or unsubstituted C4-C40 heteroaryl.
Claims12
A compound having a formula (I):
- wherein:
- A is at least one selected from:
- wherein each Ar is independently selected from substituted or unsubstituted phenyl, naphthyl, biphenyl, anthracenyl, and phenanthryl, and the substituent is one or more selected from C1-C6 alkyl and halogen;
- each R is independently selected from hydrogen atom and C1-C6 alkyl C1-C8 alkoxy, C3-C8 cycloalkyl, C6-C40 aryl, C4-C40 heteroaryl, and C7-C12 alkyl;
- and each # independently represents a connection position;
- and
- L is one or more selected from a single bond,
- wherein Y is selected from carbon atom, nitrogen atom, oxygen atom, sulfur atom, and silicon atom, and each # independently represents a connection position.
A display panel, comprising:
- an organic light-emitting device, wherein the organic light-emitting device comprises an anode, a cathode, and a light-emitting layer located between the anode and the cathode,
- wherein the light-emitting layer is made of a host material including the compound having a formula (I):
- wherein:
- A is at least one selected from:
- wherein each Ar is independently selected from substituted or unsubstituted phenyl, naphthyl, biphenyl, anthracenyl, and phenanthryl, and the substituent is one or more selected from C1-C6 alkyl and halogen;
- each R is independently selected from hydrogen atom and C1-C6 alkyl C1-C8 alkoxy, C3-C8 cycloalkyl, C6-C40 aryl, C4-C40 heteroaryl, and C7-C12 alkyl;
- and each # independently represents a connection position;
- and
- L is one or more selected from a single bond,
- wherein Y is selected from carbon atom, nitrogen atom, oxygen atom, sulfur atom, and silicon atom, and each # independently represents a connection position.
A display device, comprising:
- a display panel, comprising:
- an organic light-emitting device, wherein the organic light-emitting device comprises an anode, a cathode, and a light-emitting layer located between the anode and the cathode,
- wherein the light-emitting layer is made of a host material including the compound having a formula (I):
- wherein:
- A is at least one selected from:
- wherein each Ar is independently selected from substituted or unsubstituted phenyl, naphthyl, biphenyl, anthracenyl, and phenanthryl, and the substituent is one or more selected from C1-C6 alkyl and halogen;
- each R is independently selected from hydrogen atom and C1-C6 alkyl C1-C8 alkoxy, C3-C8 cycloalkyl, C6-C40 aryl, C4-C40 heteroaryl, and C7-C12 alkyl;
- and each # independently represents a connection position;
- and
- L is one or more selected from a single bond,
- wherein Y is selected from carbon atom, nitrogen atom, oxygen atom, sulfur atom, and silicon atom, and each # independently represents a connection position.
