Amine derivative and organic electroluminescent element

摘要

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 R1 and R2 independently represent a substituted or unsubstituted C6-40 aryl or C5-40 heteroaryl group; and R3 and R4 independently represent a hydrogen atom, a straight-chain, branched or cyclic C1-18 alkyl or C1-18 alkoxy group, or a substituted or unsubstituted C6-40 aryl or C5-40 heteroaryl group, provided that R3 and R4 may form together a cyclic hydrocarbon group. The amine derivative is useful as an organic electroluminescent material.

1. 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
R1 and R2 may be the same or different and independently represent an aryl group having 6 to 18 carbon atoms, which may have a substituent or substituents which are an alkyl group having 1 carbon atom or a heteroaryl group having 5 carbon atoms, which may have a substituent or substituents which are an alkyl group having 1 carbon atom, provided that one of R1 and R2 is an aryl group having 12 to 18 carbon atoms, which may have a substituent or substituents which are an aryl group having 1 carbon atom; and R3 and R4 may be the same or different and represent a hydrogen atom or an alkyl group having 1 carbon atom.
