An amine derivative represented by the following general formula (1) and exhibiting a temperature difference of 30° C. or more as defined by the difference of [decomposition temperature (° C.) minus sublimation temperature (° C.)]:
wherein R
1
and R
2
independently represent a substituted or unsubstituted C
6-40
aryl or C
5-40
heteroaryl group; and R
3
and R
4
independently represent a hydrogen atom, a straight-chain, branched or cyclic C
1-18
alkyl or C
1-18
alkoxy group, or a substituted or unsubstituted C
6-40
aryl or C
5-40
heteroaryl group, provided that R
3
and R
4
may form together a cyclic hydrocarbon group. The amine derivative is useful as an organic electroluminescent material.
