Abstract
To provide a novel chrysene compound and an organic light-emitting device having high emission efficiency and excellent driving durability, provided is a novel triaryl-substituted chrysene compound represented by the general formula [1]: wherein Ar1 to Ar3 each represent a substituent selected from the group consisting of a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthryl group, and a substituted or unsubstituted fluorenyl group.
Claims8
A chrysene compound represented by the general formula [1]:
- wherein R1 to R9 are each independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl group, and a substituted or unsubstituted alkoxy group;
- and
- Ar1, Ar2, and Ar3 are each independently selected from the group represented by the general formulae [2]:
- wherein X1 to X26 are each independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted phenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthryl group, and a substituted or unsubstituted fluorenyl group, provided that one of X1 to X8, one of X9 to X16, and one of X17 to X26 each represent a chrysene ring represented by the general formula [1];
- and
- Y1 and Y2 are each independently selected from a hydrogen atom and a substituted or unsubstituted alkyl group.
