PROBLEM TO BE SOLVED: To provide: a novel and improved material for organic electroluminescent devices which enables the reduction in the drive voltage of an organic electroluminescent device and the increase in light emission efficiency thereof; and an organic electroluminescent device arranged by use of such a material.SOLUTION: A material for organic electroluminescent devices comprises a monoamine derivative represented by the general formula (1). In the formula, Arrepresents a substituted or unsubstituted aryl group with 6-30 carbon atoms forming its ring, or a substituted or unsubstituted heteroaryl group with 3-30 carbon atoms forming its ring; Rto Rindependently represent a hydrogen atom, a deuterium atom, a halogen atom, a substituted or unsubstituted alkyl group with 1-30 carbon atoms, a substituted or unsubstituted aryl group with 6-30 carbon atoms forming its ring, or a substituted or unsubstituted heteroaryl group with 3-30 carbon atoms forming its ring; "n" and "m" are integers of 0-4.SELECTED DRAWING: Figure 1 |
