Definitions
- the present invention relates to a novel nitrogen-containing heterocyclic derivative, a material for an organic electroluminescence element (organic EL element) using the same, and an organic EL element, and particularly, a nitrogen-containing heterocyclic derivative useful as a component of the organic EL element.
- organic EL element organic electroluminescence element
- a nitrogen-containing heterocyclic derivative useful as a component of the organic EL element Is used for at least one of the organic compound layers, which relates to an organic EL element having high luminous efficiency while being low in voltage.
- an organic EL element using an organic substance is considered to be promising for use as an inexpensive large-area full-color display element of a solid light emitting type, and many developments have been made.
- an organic EL element is composed of a light emitting layer and a pair of counter electrodes sandwiching the layer. In light emission, when an electric field is applied between both electrodes, electrons are injected from the cathode side and holes are injected from the anode side. Furthermore, this is a phenomenon in which electrons recombine with holes in the light emitting layer to generate an excited state, and energy is emitted as light when the excited state returns to the ground state.
- Patent Document 1 discloses an element using a compound having a benzimidazole structure as a light-emitting material, and describes that the element emits light with a luminance of 200 cd / m 2 at a voltage of 9 V.
- Patent Documents 2 and 3 describe compounds having a benzimidazole ring and an anthracene skeleton. However, those having higher emission luminance and emission efficiency than those of organic EL devices using these compounds are demanded.
- the present invention has been made to solve the above-described problems, and provides a novel nitrogen-containing heterocyclic derivative useful as a component of an organic EL device, and this nitrogen-containing heterocyclic derivative is added to at least one layer of an organic compound layer. It is an object of the present invention to realize an organic EL element having high emission luminance and high emission efficiency while being at a low voltage.
- the present inventors have used a novel nitrogen-containing heterocyclic derivative having a specific structure in at least one organic compound layer of an organic EL device, The present inventors have found that it is possible to achieve a low voltage and high efficiency of an organic EL element, and have completed the present invention.

正孔注入層及び正孔輸送層の材料としては、特に制限はなく、従来、光導伝材料において正孔の電荷輸送材料として慣用されているものや、有機EL素子の正孔注入層及び正孔輸送層に使用されている公知のものの中から任意のものを選択して用いることができる。
Ar232とAr233は互いに連結して飽和もしくは不飽和の環を形成してもよい。ここで置換もしくは無置換の環形成炭素数6~50のアリール基およびアリーレン基、及び置換もしくは無置換の環形成原子数5~50のヘテロアリール基およびヘテロアリーレン基の具体例としては、前記と同様のものがあげられる。
正孔注入層及び正孔輸送層は上述した化合物を、真空蒸着法、スピンコート法、キャスト法、LB法等の公知の方法により薄膜化することにより形成することができる。正孔注入層及び正孔輸送層の膜厚は特に制限はないが、通常は5nm~5μmである。正孔注入層及び正孔輸送層は上述した材料の一種又は二種以上からなる一層で構成されてもよいし、異なる化合物からなる複数の正孔注入層及び正孔輸送層を積層したものであってもよい。
本発明の含窒素複素環誘導体を電子輸送帯域に用いる場合、本発明の含窒素複素環誘導体単独で電子注入・輸送層を形成してもよく、他の材料と混合してもよい。
本発明の含窒素複素環誘導体と混合して電子注入層、電子輸送層を形成する材料としては、前記の好ましい性質を有するものであれば特に制限はなく、従来、光導伝材料において電子の電荷輸送材料として慣用されているものや、有機EL素子の電子注入層、電子輸送層に使用される公知のものの中から任意のものを選択して用いることができる。
また付着改善層は、この電子注入層の中で特に陰極との付着が良い材料からなる層である。本発明の有機EL素子においては、上記本発明化合物を電子注入層、電子輸送層、付着改善層として用いることが好ましい。
また、より具体的に、好ましい還元性ドーパントとしては、Na(仕事関数:2.36eV)、K(仕事関数:2.28eV)、Rb(仕事関数:2.16eV)およびCs(仕事関数:1.95eV)からなる群から選択される少なくとも一つのアルカリ金属や、Ca(仕事関数:2.9eV)、Sr(仕事関数:2.0~2.5eV)、およびBa(仕事関数:2.52eV)からなる群から選択される少なくとも一つのアルカリ土類金属が挙げられる仕事関数が2.9eV以下のものが特に好ましい。これらのうち、より好ましい還元性ドーパントは、K、RbおよびCsからなる群から選択される少なくとも一つのアルカリ金属であり、さらに好ましくは、RbまたはCsであり、最も好ましのは、Csである。これらのアルカリ金属は、特に還元能力が高く、電子注入域への比較的少量の添加により、有機EL素子における発光輝度の向上や長寿命化が図られる。また、仕事関数が2.9eV以下の還元性ドーパントとして、これら2種以上のアルカリ金属の組合わせも好ましく、特に、Csを含んだ組み合わせ、例えば、CsとNa、CsとK、CsとRbあるいはCsとNaとKとの組み合わせであることが好ましい。Csを組み合わせて含むことにより、還元能力を効率的に発揮することができ、電子注入域への添加により、有機EL素子における発光輝度の向上や長寿命化が図られる。
また、電子輸送層を構成する半導体としては、Ba、Ca、Sr、Yb、Al、Ga、In、Li、Na、Cd、Mg、Si、Ta、SbおよびZnの少なくとも一つの元素を含む酸化物、窒化物または酸化窒化物等の一種単独または二種以上の組み合わせが挙げられる。また、電子輸送層を構成する無機化合物が、微結晶または非晶質の絶縁性薄膜であることが好ましい。電子輸送層がこれらの絶縁性薄膜で構成されていれば、より均質な薄膜が形成されるために、ダークスポット等の画素欠陥を減少させることができる。なお、このような無機化合物としては、上述したアルカリ金属カルコゲニド、アルカリ土類金属カルコゲニド、アルカリ金属のハロゲン化物およびアルカリ土類金属のハロゲン化物等が挙げられる。
この陰極はこれらの電極物質を蒸着やスパッタリング等の方法により薄膜を形成させることにより、作製することができる。
ここで発光層からの発光を陰極から取り出す場合、陰極の発光に対する透過率は10%より大きくすることが好ましい。
また、陰極としてのシート抵抗は数百Ω/□以下が好ましく、膜厚は通常10nm~1μm、好ましくは50~200nmである。
以下、透光性基板上に陽極/正孔注入層/発光層/電子注入層/陰極が順次設けられた構成の有機EL素子の作製例を記載する。
まず、適当な透光性基板上に陽極材料からなる薄膜を1μm以下、好ましくは10~200nmの範囲の膜厚になるように蒸着やスパッタリング等の方法により形成して陽極を作製する。次に、この陽極上に正孔注入層を設ける。正孔注入層の形成は、前述したように真空蒸着法、スピンコート法、キャスト法、LB法等の方法により行うことができるが、均質な膜が得られやすく、かつピンホールが発生しにくい等の点から真空蒸着法により形成することが好ましい。真空蒸着法により正孔注入層を形成する場合、その蒸着条件は使用する化合物(正孔注入層の材料)、目的とする正孔注入層の結晶構造や再結合構造等により異なるが、一般に蒸着源温度50~450℃、真空度10-7~10-3Torr、蒸着速度0.01~50nm/秒、基板温度-50~300℃、膜厚5nm~5μmの範囲で適宜選択することが好ましい。
次に、この発光層上に電子注入層を設ける。正孔注入層、発光層と同様、均質な膜を得る必要から真空蒸着法により形成することが好ましい。蒸着条件は正孔注入層、発光層と同様の条件範囲から選択することができる。
本発明の含窒素複素環誘導体は、発光帯域や正孔輸送帯域のいずれの層に含有させるかによって異なるが、真空蒸着法を用いる場合は他の材料との共蒸着をすることができる。また、スピンコート法を用いる場合は、他の材料と混合することによって含有させることができる。
最後に陰極を積層して有機EL素子を得ることができる。
陰極は金属から構成されるもので、蒸着法、スパッタリングを用いることができる。しかし下地の有機物層を製膜時の損傷から守るためには真空蒸着法が好ましい。
この有機EL素子の作製は一回の真空引きで一貫して陽極から陰極まで作製することが好ましい。
本発明の有機EL素子の各有機層の膜厚は特に制限されないが、一般に膜厚が薄すぎるとピンホール等の欠陥が生じやすく、逆に厚すぎると高い印加電圧が必要となり効率が悪くなるため、通常は数nmから1μmの範囲が好ましい。
なお、有機EL素子に直流電圧を印加する場合、陽極を+、陰極を-の極性にして、5~40Vの電圧を印加すると発光が観測できる。また、逆の極性で電圧を印加しても電流は流れず、発光は全く生じない。さらに交流電圧を印加した場合には陽極が+、陰極が-の極性になった時のみ均一な発光が観測される。印加する交流の波形は任意でよい。
