Claims8
A hole transport material for an organic electroluminescence (EL) device, the hole transport material being represented by Formula 1, below:
- wherein:
- Ar1 is an aryl group having 6 to 20 carbon atoms,
- R1 to R7 are each independently a substituted or unsubstituted straight-chain alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted branched-chain alkyl group having 3 to 10 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, or a heteroaryl group having 5 to 20 carbon atoms,
- a to g are integers indicating the number of substituent R1 to R7,
- each R1 is different from or the same as each other R1,
- each R2 is different from or the same as each other R2,
- each R3 is different from or the same as each other R3,
- each R4 is different from or the same as each other R4,
- each R5 is different from or the same as each other R5,
- each R6 is different from or the same as each other R6,
- each R7 is different from or the same as each other R7,
- X of ring A is a methine group, a carbon atom, or a nitrogen atom, and
- Y is an oxygen atom or a sulfur atom.
