An anthracene compound having formula (I)
- wherein R1, and R2, are each individually an unsubstituted or substituted aryl group having 6 to 20 carbon atoms, an unsubstituted or substituted heteroaryl group having 6 to 20 carbon atoms, wherein the substituent is C1-10 alkyl, C1-10 alkoxy, or halogen;
- and
- R5, and R6 are each individually an unsubstituted or substituted phenyl group, an unsubstituted or substituted heteroaryl group having 6 to 20 carbon atoms, or an unsubstituted or substituted alkyl group having 1 to 12 carbon atoms, wherein the substituent is C1-10 alkyl, C1-10 alkoxy, or halogen.
An organic electroluminescent device, comprising a pair of electrodes and a layer of organic light emitting medium disposed between the pair of electrodes,
- wherein the layer of organic light emitting medium includes an anthracene compound having formula (I)
- wherein R1, and R2, are each individually an unsubstituted or substituted aryl group having 6 to 20 carbon atoms, an unsubstituted or substituted heteroaryl group having 6 to 20 carbon atoms, wherein the substituent is C1-10 alkyl, C1-10 alkoxy, or halogen;
- and
- R5, and R6 are each individually an unsubstituted or substituted phenyl group, an unsubstituted or substituted heteroaryl group having 6 to 20 carbon atoms, or an unsubstituted or substituted alkyl group having 1 to 12 carbon atoms, wherein the substituent is C1-10 alkyl, C1-10 alkoxy or halogen.
