【発明の属する技術分野】
本発明は、新規なアミン化合物に関し、また該化合物を有する有機電界発光素子に関する。
【0002】
【従来の技術】
近年、各種の有機化合物が、表示材料や記録材料など、種々の機能を有する材料として盛んに開発が進められている。
【0003】
例えば、最近では、素子の構成材料に有機化合物を用いた有機電界発光素子(有機エレクトロルミネッセンス素子;有機EL素子)が開発された〔Appl.Phys.Lett.,51,913(1987)〕。有機電界発光素子は、蛍光性有機化合物を含む薄膜を、陽極と陰極の間に挟持された構造を有し、該薄膜に電子および正孔(ホール)を注入して、再結合させることにより励起子(エキシトン)を生成させ、この励起子が失活する際に放出される光を利用して発光する素子である。有機電界発光素子は、数V〜数十V程度の直流の低電圧で発光が可能であり、また蛍光性有機化合物を選択することにより、種々の色(例えば、赤色、青色、緑色)の発光が可能である。このような特徴を有する有機電界発光素子は、種々の発光素子、表示素子などへの応用が期待されている。しかしながら、一般に、有機電界発光素子は、安定性、耐久性に乏しいなどの難点がある。さらに発光輝度が低く、実用上充分でない。
【0004】
正孔注入輸送材料として、4,4’−ビス〔N−フェニル−N−(3”−メチルフェニル)アミノ〕ビフェニルを用いることが提案されている〔Jpn.J.Appl.Phys.,27,L269(1988)〕。しかしながら、この化合物を正孔注入輸送材料とする有機電界発光素子も、安定性、耐久性に乏しいなどの難点がある。
【0005】
また、特開平3−269084号公報において、正孔注入輸送層に、α、α、α’、α’−ビス(4−ジ−パラ−トリルアミノフェニル)−パラ−キシレンを含むことを特徴とする有機薄膜EL素子が、特開平5−105651号公報において、感光体、エレクトロルミネッセンス素子の電荷輸送材料として使用可能な有機化合物として、一般式(2)で表される化合物
【0006】
【化2】
【0007】
[式中、J1およびJ2はそれぞれ、置換基を有してもよいアルキル基、アラルキル基、アリール基、ビフェニル基または複素環式基;K1、K2、K3、K4、K5はそれぞれ水素原子、アルキル基、アルコキシ基またはハロゲン原子;Lは−O−、−S−または、一般式(3)で表される基を表す。
【0008】
【化3】
【0009】
(K6およびK7はそれぞれ水素原子、置換基を有していてもよいアルキル基、またはアリール基;nは1〜4の整数を表す)]が開示されているが、これらの化合物を有機電界発光素子の正孔注入輸送層として使用する場合、素子中の他の材料との適合性、素子の安定性、耐久性を満足するものではない。
現在では、一層改良された有機電界発光素子が望まれており、新規な有機材料が求められている。
【0010】
【発明が解決しようとする課題】
本発明の課題は、新規なアミン化合物を提供することにあり、加えて、該化合物を用いた、安定性、耐久性の改良された有機電界発光素子を提供することにある。
【0011】

BACKGROUND OF THE INVENTION

[Prior art]
In recent years, various organic compounds have been actively developed as materials having various functions such as display materials and recording materials.
[0003]
For example, recently, an organic electroluminescence element (organic electroluminescence element; organic EL element) using an organic compound as a constituent material of the element has been developed [Appl. Phys. Lett.,51913 (1987)]. An organic electroluminescent element has a structure in which a thin film containing a fluorescent organic compound is sandwiched between an anode and a cathode, and is excited by injecting electrons and holes into the thin film and recombining them. It is an element that emits light using light emitted when excitons are deactivated by generating excitons. The organic electroluminescence device can emit light at a low direct current voltage of several volts to several tens of volts, and emits various colors (for example, red, blue, green) by selecting a fluorescent organic compound. Is possible. The organic electroluminescent device having such characteristics is expected to be applied to various light emitting devices and display devices. However, in general, organic electroluminescent elements have drawbacks such as poor stability and durability. Further, the luminance is low, which is not sufficient for practical use.
[0004]
It has been proposed to use 4,4′-bis [N-phenyl-N- (3 ″ -methylphenyl) amino] biphenyl as a hole injecting and transporting material [Jpn. J. Appl. Phys., 27, L269 (1988)] However, an organic electroluminescent device using this compound as a hole injecting and transporting material also has drawbacks such as poor stability and durability.
[0005]
Further, in JP-A-3-269084, the hole injecting and transporting layer contains α, α, α ′, α′-bis (4-di-para-tolylaminophenyl) -para-xylene. An organic thin film EL element is a compound represented by the general formula (2) as an organic compound that can be used as a charge transport material for a photoreceptor and an electroluminescence element in JP-A-5-105651.
