Beschreibung
Zusammenfassung:	A material for an organic electroluminescence device includes a compound composed of a specific structure showing enhanced steric hindrance. An organic electroluminescence device includes an organic thin film layer composed of one or more layers including at least a light emitting layer, the organic thin film layer is sandwiched between a cathode and an anode, in which at least one layer of the organic thin film layer contains the material for organic electroluminescence device. There are provided the organic electroluminescence device and the material for an organic electroluminescence device having a high luminescent efficiency, excellent heat resistance, and a long lifetime.
