Claims7
An aryl amine derivative represented by the following Chemical Formula 1,
- wherein, in Chemical Formula 1:
- Ar1, Ar2, and Ar3 are each independently a substitutable aryl group or a substitutable heteroaryl group,
- L is a single bond, a substitutable C6 to C25 arylene group, or a substitutable C5 to C25 heteroarylene group,
- n is an integer of 1 to 3,
- X1, X2, and X3 are each independently a carbon atom or a nitrogen atom, provided that at least one of X1, X2, or X3 is a nitrogen atom.
