The present invention provides an organic electroluminescent device material of high efficiency and long life and an organic electroluminescent device using the same. The organic electroluminescent device material according to the present invention is a monoamine compound which is displayed as the formula (1). In the formula (1), X^1 is one selected from O, S, R^9-C-R^10, or N-R^11, and R^1-R^11 are individually an alkyl group having 10 or fewer carbon atoms, an aryl group having 6-30 atoms for ring formation, an alkyloxy group, an alkylthio group, a trialkylsilyl group, an aryloxy group, an arylthio group, a triarylsilyl group, an alkyldiarylsilyl group, dialkylarylsilyl group or a heteroaryl group having 2-30 carbon atoms for ring formation. The n is an integer of 0-4 inclusive; the m is an integer of 0-3 inclusive; and the o is an integer of 0-2 inclusive. |
