## Claims

### Claim 1

An amine derivative having a phenanthroimidazole group, the amine derivative being represented by Formula 1, below:
wherein:
Ar1, Ar2, and Ar3 are each independently one of a substituent aryl group or a substituent heteroaryl group, and
at least one of Ar1, Ar2, or Ar3 has at least 12 carbon atoms.

### Claim 2 (depends on 1)

The amine derivative as claimed in claim 1, wherein the amine derivative having the phenanthroimidazole group is represented by Formula 2, below:
wherein Ar1, Ar2, and Ar3 are as defined with respect to Formula 1.

### Claim 3 (depends on 1)

The amine derivative as claimed in claim 1, wherein Ar1, Ar2, and Ar3 are different substituents from one another.

### Claim 4 (depends on 1)

The amine derivative as claimed in claim 1, wherein Ar1, Ar2, and Ar3 are each independently one of a substituent dibenzoheterole group or a substituent aryl group having 6 to 18 carbon atoms.

### Claim 5 (depends on 1)

The amine derivative as claimed in claim 1, wherein Ar1, Ar2, and Ar3 are each independently one of a substituent dibenzofuran, a substituent dibenzothiophene, a substituent carbazole, a substituent fluorene, or a substituent phenyl.

### Claim 6 (depends on 1)

An organic electroluminescence material comprising an amine derivative having a phenanthroimidazole group as claimed in claim 1.

### Claim 7 (depends on 1)

An electroluminescence device, comprising:
an anode;
a cathode; and
a light-emitting layer and a hole transport layer between the cathode and the anode,
wherein the hole transport layer includes an amine derivative having the phenanthroimidazole group as claimed in claim 1.
