PROBLEM TO BE SOLVED: To provide a material for an organic electroluminescent element having high light-emitting efficiency and a long life with a low driving voltage and to provide an organic electroluminescent element using the same.SOLUTION: A compound formed by introducing a dibenzoheterole part or a fluorene part into a [1,1':3',1''-terphenyl]-2'-amino group improves amorphous properties while maintaining characteristics of amine. Particularly, by being used for a hole transport layer 108, high light-emitting efficiency and a long life can be achieved with a low driving voltage.SELECTED DRAWING: Figure 1 |
