- the present invention relates to an organic electroluminescence element and an electronic device including the organic electroluminescence element. Furthermore, it is related with the compound which can be used as a material for organic electroluminescent elements.
- an organic electroluminescence (EL) element is composed of an anode, a cathode, and one or more organic thin film layers sandwiched between the anode and the cathode.
- a voltage is applied between both electrodes, electrons from the cathode side and holes from the anode side are injected into the light emitting region, and the injected electrons and holes recombine in the light emitting region to generate an excited state, which is excited.
- Light is emitted when the state returns to the ground state.
- organic EL elements can be obtained in various light emitting colors by using various light emitting materials for the light emitting layer, and therefore, researches for practical application to displays and the like are active. In particular, research on light emitting materials of the three primary colors of red, green, and blue is the most active, and intensive research has been conducted with the aim of improving characteristics.

前述の本発明の化合物が含まれる有機薄膜層の例としては、正孔輸送層、発光層、電子輸送層、スペース層及び障壁層などが挙げられるが、特にこれらに限定されるものではない。
本発明の化合物の中でも、特に発光効率及び素子寿命の観点から、アミノ基を含有する化合物は、発光層に含まれることが好ましく、特にドーパント材料として発光層に含まれることが好ましい。また、ヘテロアリール基、特に含窒素ヘテロアリール基を含有する化合物は、特に、電子輸送層や、発光層と電子輸送層との間の障壁層に含まれることが好ましい。さらに、特に駆動電圧及び発光効率の観点から、アントラセン骨格を有する化合物は、発光層に含まれることが好ましく、ホスト材料、特に蛍光ホスト材料として発光層に含まれることが好ましい。

Ar1とAr2、Ar3とAr4で環を形成してもよい。
また、前記式(I)において、Lは置換もしくは無置換の環形成炭素数6~50(好ましくは6~30、より好ましくは6~20、さらに好ましくは6~12)の芳香族炭化水素基もしくは置換基を有していてもよい環形成炭素数6~50(好ましくは6~30、より好ましくは6~20、さらに好ましくは6~12)の縮合芳香族炭化水素基、又は置換もしくは無置換の環形成原子数5~50(好ましくは5~30、より好ましくは5~20、さらに好ましくは5~12)の芳香族複素環基もしくは置換もしくは無置換の環形成原子数5~50(好ましくは5~30、より好ましくは5~20、さらに好ましくは5~12)の縮合芳香族複素環基を表す。
上述の正孔輸送層や電子輸送層においては、特許第3695714号明細書に記載されているように、ドナー性材料のドーピング(n)やアクセプター性材料のドーピング(p)により、キャリア注入能を調整することができる。
nドーピングの代表例としては、電子輸送材料にLiやCsなどの金属をドーピングする方法が挙げられ、pドーピングの代表例としては、正孔輸送材料にF4TCNQなどのアクセプター材料をドーピングする方法が挙げられる。
上記スペース層とは、例えば、蛍光発光層と燐光発光層とを積層する場合に、燐光発光層で生成する励起子を蛍光発光層に拡散させない、あるいは、キャリアバランスを調整する目的で、蛍光発光層と燐光発光層との間に設けられる層である。また、スペース層は、複数の燐光発光層の間に設けることもできる。
スペース層は発光層間に設けられるため、電子輸送性と正孔輸送性を兼ね備える材料であることが好ましい。また、隣接する燐光発光層内の三重項エネルギーの拡散を防ぐため、三重項エネルギーが2.6eV以上であることが好ましい。スペース層に用いられる材料としては、上述の正孔輸送層に用いられるものと同様のものが挙げられる。
本発明の有機EL素子は、発光層に隣接する部分に、電子障壁層、正孔障壁層、トリプレット障壁層といった障壁層を有することが好ましい。ここで、電子障壁層とは、発光層から正孔輸送層へ電子が漏れることを防ぐ層であり、発光層と正孔輸送層との間に設けられる層である。また、正孔障壁層とは、発光層から電子輸送層へ正孔が漏れることを防ぐ層であり、発光層と電子輸送層との間に設けられる層である。
トリプレット障壁層は、後述するように、発光層で生成する三重項励起子が、周辺の層へ拡散することを防止し、三重項励起子を発光層内に閉じ込めることによって三重項励起子の発光ドーパント材料以外の電子輸送層の分子上でのエネルギー失活を抑制する機能を有する。
電子注入層は、電界強度0.04~0.5MV/cmの範囲において、10-6cm2/Vs以上であることが望ましい。これにより陰極からの電子輸送層への電子注入が促進され、ひいては隣接する障壁層、発光層への電子注入も促進し、より低電圧での駆動を可能にするためである。
本発明の化合物を用いて得られる有機EL素子は、発光効率がさらに改善されている。このため、有機ELパネルモジュールなどの表示部品;テレビ、携帯電話、パーソナルコンピュータなどの表示装置;照明、車両用灯具の発光装置、などの電子機器に使用できる。
