AROMATIC AMINE DERIVATIVES AND ORGANIC ELECTROLUMINESCENCE DEVICES USING THE SAME

摘要

It is intended to provide a novel aromatic amine derivative having a specific structure; and an organic electroluminescence device having a monolayered or multilayered organic film layer which contains at least a luminescent layer and is sandwiched between an anode and a cathode, wherein at least one layer (more specifically, a hole injection layer) of the organic film layer contains the above-described aromatic amine derivative either as a single component or one of the components of a mixture. Use of this organic electroluminescence device makes it possible to prevent the molecules from crystallization while lowering the driving voltage. Thus, the organic electroluminescence device can be produced at an elevated yield and has a prolonged life. These advantages can be established by the aromatic amine derivative.
