Claims6
A hole transport material for an organic electroluminescence device, the hole transport material being a compound represented by following Formula 1:
- wherein, Idc is an indolocarbazole group linked to ring A and ring B,
- each X of ring A is independently a methine group or a nitrogen atom, at least one X of ring A being a nitrogen atom,
- Y is a methylene group, an oxygen atom, or a sulfur atom,
- Ar1 is an aryl group having 6 to 20 carbon atoms,
- each of R1-R5 independently represents a substituted or unsubstituted straight or branched chain alkyl group having 6 to 20 carbon atoms, or an aryl group or a heteroaryl group having 6 to 20 carbon atoms,
- a is an integer of 0 to 9,
- b is an integer of 0 to 4,
- c is an integer of 0 to 10,
- d is an integer of 0 to 5, and
- e is an integer of 0 to 10.
