First claim
Opening claim text (preview).
What is claimed is: 1. A material for an organic electroluminescent device, the material comprising a monoamine compound represented by the following Formula 1: wherein, in Formula 1, R 1 and R 2 are each independently a hydrogen atom, a halogen atom, an alkyl group having 1 to 15 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, or a substituted or unsubstituted heteroaryl group having 1 to 30 ring carbon atoms, and Ar 1 is a substituted or unsubstituted phenanthrenyl group. 2. The material for an organic electroluminescent device as claimed in claim 1 , wherein all dibenzofuranyl groups that are directly bonded with a nitrogen atom of the monoamine are bound to the nitrogen atom at a 3 position of the dibenzofuranyl group. 3. A material for an organic electroluminescent device, wherein the material includes one of the following compounds: 4. An organic electroluminescent device comprising the material for an organic electroluminescent device as claimed in claim 1 . 5. The organic electroluminescent device as claimed in claim 4 , wherein the material for an organic electroluminescent device is included in a hole transport layer. 6. An organic electroluminescent device comprising a material for an organic electroluminescent device, wherein the material includes one of the following compounds:
