L1 to L3 are any one selected from the group consisting of a direct bond; a substituted or unsubstituted alkylene group; a substituted or unsubstituted cycloalkylene group; a substituted or unsubstituted alkenylene group; a substituted or unsubstituted aralkylene group; a substituted or unsubstituted aralkenylene group; a substituted or unsubstituted alkylarylene group; a substituted or unsubstituted divalent amine group; a substituted or unsubstituted divalent aralkylamine group; a substituted or unsubstituted divalent arylamine group; a substituted or unsubstituted arylene group; and a substituted or unsubstituted heterocyclic group,

Ar1 and Ar2 are each independently any one selected from a group consisting of hydrogen;

deuterium; a halogen group; a nitrile group; a nitro group; a substituted or unsubstituted amine group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryl group; a substituted or unsubstituted fluorene group; and a substituted or unsubstituted heterocyclic group,

L1 to L3, Ar1, and Ar2 optionally combine with an adjacent group to form a substituted or unsubstituted ring,

n and m are each an integer of 0 to 6,

o+s is an integer of 1 to 4, and

s, p, and q are an integer of 1 to 4.

2. The compound of claim 1 , wherein L1 to L3 are any one of the following chemical formulae:

3. The compound of claim 1 , wherein Ar1 and Ar2 are each independently any one selected from a group consisting of a substituted or unsubstituted aryl group; a substituted or unsubstituted fluorene group; and a substituted or unsubstituted heterocyclic group.

4. The compound of claim 1 , wherein the substituted or unsubstituted ring formed by combining Ar1 and Ar2 with each other is any one of the following chemical formulae:

R4 to R9 are each independently selected from a group consisting of a substituted or unsubstituted alkyl group; a substituted or unsubstituted aryl group; a substituted or unsubstituted fluorene group; and a substituted or unsubstituted heterocyclic group,

a is an integer of 1 to 10, and

b to e are each an integer of 1 to 8.

5. The compound of claim 1 , wherein the substituted or unsubstituted ring formed by combining L1 to L3 and Ar1 or Ar2 with each other is any one of the following chemical formulae:

R10 to R15 are each independently selected from a group consisting of a substituted or unsubstituted alkyl group; a substituted or unsubstituted aryl group; a substituted or unsubstituted fluorene group; and a substituted or unsubstituted heterocyclic group,

Ar3 is Ar1 or Ar2,

f is an integer of 1 to 9, and

g to j are each an integer of 1 to 7.

6. The compound of claim 1 , wherein the compound is any one of the following chemical formulae:

7. An organic light emitting device comprising:

a first electrode;

a second electrode provided to face the first electrode; and

one or more organic material layers provided between the first electrode and the second electrode,

wherein one or more layers of the organic material layers comprise the compound of claim 1 .

8. The organic light emitting device of claim 7 , wherein the organic material layer is composed of the compound alone or composed of the doped compound.

9. The organic light emitting device of claim 7 , wherein the organic material layer is a hole injection layer, a hole transport layer, an electron transport layer, or an electron injection layer.

10. The organic light emitting device of claim 7 , wherein the organic material layer is a layer which injects and transports holes simultaneously.

11. The organic light emitting device of claim 7 , wherein the organic material layer is a layer which transports and injects electrons simultaneously.

12. The organic light emitting device of claim 7 , wherein the organic material layer is a light emitting layer.
