Definitions
- the present invention relates to an aromatic amine derivative and an organic electroluminescence device using the same.
- organic electroluminescence element is a self-luminous element utilizing the principle that a fluorescent substance emits light by recombination energy of holes injected from an anode and electrons injected from a cathode by applying an electric field. It is. Eastman Kodak's C.I. W. Since the report of the low voltage drive organic EL element by the multilayer element by Tang et al. (See Non-Patent Document 1), research on the organic EL element having an organic material as a constituent material has been actively conducted. Tang et al.
- an organic EL device having a laminated structure using tris (8-quinolinolato) aluminum as a light emitting layer and a triphenyldiamine derivative as a hole transporting layer.
- Advantages of the laminated structure in the organic EL element are (i) that the efficiency of hole injection into the light emitting layer can be increased, and (ii) electrons injected from the cathode into the light emitting layer can be used as the hole transport (injection) layer.
- the efficiency of excitons generated by recombination in the light emitting layer can be increased, and (iii) excitons generated in the light emitting layer can be easily confined in the light emitting layer.
- the device structure and the formation method have been studied, and the material of each layer itself has been studied.
- Patent Documents 1 to 3 are not satisfactory in terms of the light emission efficiency and device lifetime of the organic EL device, and there is room for further improvement.
- Patent Document 3 succeeds in driving the organic EL element at a low voltage, but the ionization potential value of the aromatic amine derivative having a fluorene skeleton is smaller than the ionization potential value of the host material used in the light emitting layer.
- the aromatic amine derivative is used as a hole transport material for an organic EL device, the energy barrier between the hole transport layer and the light emitting layer is large, and hole injection into the light emitting layer is suppressed. There was a problem that the luminous efficiency was not sufficient.
- this invention makes it a subject to provide the organic EL element material which can improve luminous efficiency and element lifetime rather than the conventional organic EL element material, and an organic EL element using the same.
- an aromatic amine derivative having an aromatic hydrocarbon group having a specific structure and a substituted or unsubstituted phenyl group as a material for an organic EL device.
- Ar 1 is an organic group A represented by the following general formula (A-1) or (A-2); Ar 2 is the organic group A; B-1) is an organic group B, and Ar 3 is an organic group C represented by the following general formula (C-1).
- Ar 1 and Ar 2 are organic groups A, each organic group A may be the same or different.
- Ar 4 is a substituted or unsubstituted condensed ring group having 10 to 14 ring carbon atoms.
- R 1 and R 2 are each independently a hydrogen atom, an alkyl group, a cycloalkyl group or ring aryl group having 6 to 12 ring carbon atoms 3-10 1-10 carbon atoms, R 1 And R 2 may combine to form a hydrocarbon ring.

なお、本発明の芳香族アミン誘導体の製造方法に特に制限は無く、本明細書の実施例の記載を参照しながら、公知の方法を利用及び応用して製造することができる。以下に、その製造方法の一例を示すが、特に制限されるものではない。
まず、ハロゲン化合物である下記中間体Xを合成する。
例えば、1-ナフチルボロン酸と4-ヨード-1-ブロモ(9,9-ジメチル)フルオレンとを、触媒〔例えば、テトラキス(トリフェニルフォスフィン)パラジウム(0)〕の存在下、溶媒〔例えば、トルエン〕と塩基〔例えば、炭酸ナトリウム〕を含む水溶液中で、室温(約20℃)~150℃で反応させ、適宜通常の有機化合物の分離精製手段によって分離精製することにより、中間体Xを得ることができる。なお、反応はアルゴンなどの不活性ガス雰囲気下で行なうのが好ましい。
ハロゲン化物〔例えば、4-ブロモ-p-ターフェニル〕、アミノ基を生成させる化合物(置換もしくは無置換の環形成炭素数6~30のアリール基を生成させる化合物を含んでもよい)〔例えば、アニリン〕を、触媒(トリス(ジベンジリデンアセトン)及びトリ-t-ブチルホスフィン〕の存在下、溶媒〔例えば、トルエン〕中、50~150℃で反応させる。その後、通常の有機化合物の分離精製手段によって分離精製することにより、中間体Yを得ることができる。なお、反応はアルゴンなどの不活性ガス雰囲気下で行なうのが好ましい。
反応終了後、室温まで冷却し、水を加えて反応生成物を濾過し、濾液をトルエンなどの溶媒で抽出し、無水硫酸マグネシウムなどの乾燥剤で乾燥させる。これを減圧下で脱溶媒して濃縮する。得られた粗生成物をカラム精製し、トルエンなどの溶媒で再結晶し、それを濾別して乾燥することにより、精製された本発明の芳香族アミン誘導体が得られる。
以下、本発明の有機EL素子の構成について説明する。
本発明の有機EL素子の代表的な素子構成としては、以下の素子構成を挙げることができるが、特にこれらに限定されるものではない。なお、(4)の素子構成が好ましく用いられる。
(1)陽極/正孔輸送層/発光層/陰極
(2)陽極/正孔注入層/正孔輸送層/発光層/陰極
(3)陽極/正孔注入層/正孔輸送層/発光層/電子注入層/陰極
(4)陽極/正孔注入層/正孔輸送層/発光層/電子輸送層/電子注入層/陰極
なお、正孔輸送層と発光層との間には、適宜、電子障壁層を設けてもよい。また、発光層と電子注入層との間や、発光層と電子輸送層との間には、適宜、正孔障壁層を設けてもよい。電子障壁層や正孔障壁層によれば、電子又は正孔を発光層に閉じ込めて、発光層における電荷の再結合確率を高め、発光効率を向上させることができる。
また、正孔注入層、発光層、電子注入層は、それぞれ二層以上の層構成により形成されてもよい。その際には、正孔注入層の場合、電極から正孔を注入する層を正孔注入層、正孔注入層から正孔を受け取り発光層まで正孔を輸送する層を正孔輸送層と呼ぶ。同様に、電子注入層の場合、電極から電子を注入する層を電子注入層、電子注入層から電子を受け取り発光層まで電子を輸送する層を電子輸送層と呼ぶ。
これらの各層は、材料のエネルギー準位、耐熱性、有機層又は金属電極との密着性などの各要因により選択されて使用される。
本発明の芳香族アミン誘導体を1つの有機薄膜層、好ましくは正孔注入層又は正孔輸送層に含有させる量は、有機EL素子の発光効率及び素子寿命の観点から、その有機薄膜層の全成分に対して、好ましくは30~100質量%であり、より好ましくは50~100質量%であり、さらに好ましくは80~100質量%であり、特に好ましくは実質100質量%である。
以下、好ましい形態として、本発明の前記芳香族アミン誘導体を正孔輸送層に含有させた構成の有機EL素子の各層について説明する。
有機EL素子は、通常、透光性の基板上に作製する。この透光性の基板は有機EL素子を支持する基板であり、その透光性については、波長400~700nmの可視領域の光の透過率が50%以上であるものが望ましく、さらに平滑な基板を用いるのが好ましい。

この陰極は、これらの電極物質を蒸着やスパッタリングなどの方法により薄膜を形成することにより得られる。
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、さらに、陰極の膜厚は、通常10nm~1μm、好ましくは50nm~200nmである。
また、一般的に、有機EL素子は、超薄膜に電界を印加するために、リークやショートによる画素欠陥が生じやすいため、これを防止するために、一対の電極間に絶縁性の薄膜層からなる絶縁層を挿入してもよい。

正孔注入層・正孔輸送層は、発光層への正孔注入を助け、発光領域まで輸送する層であって、正孔移動度が大きく、イオン化エネルギーが通常5.7eV以下と小さい。このような正孔注入層・正孔輸送層としては、より低い電界強度で正孔を発光層に輸送する材料が好ましく、さらに正孔の移動度が、例えば104~106V/cmの電界印加時に、10-4cm2/V・秒以上であることが好ましい。
前記のように、本発明の芳香族アミン誘導体は、正孔注入層又は正孔輸送層に、特に正孔輸送層に好ましく用いられる。本発明の芳香族アミン誘導体を正孔注入層及び正孔輸送層の双方に用いる場合、それぞれの芳香族アミン誘導体は同一でも異なっていてもよい。

電子注入層・電子輸送層は、発光層への電子の注入を助け、発光領域まで輸送する層であって、電子移動度が大きい。また、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(付着改善層)を有していてもよい。
有機EL素子は、発光した光が電極(この場合は陰極)により反射するため、直接陽極から取り出される発光と、電極による反射を経由して取り出される発光とが干渉することが知られている。この干渉効果を効率的に利用するため、電子輸送層は数nm~数μmの膜厚で適宜選ばれるが、特に膜厚が厚いとき、電圧上昇を避けるために、104~106V/cmの電界印加時に電子移動度が少なくとも10-5cm2/Vs以上であることが好ましい。
電子注入層に用いられる材料としては、具体的には、フルオレノン、アントラキノジメタン、ジフェノキノン、チオピランジオキシド、オキサゾール、オキサジアゾール、トリアゾール、イミダゾール、ペリレンテトラカルボン酸、フレオレニリデンメタン、アントラキノジメタン、アントロンなどとそれらの誘導体が挙げられるが、特にこれらに限定されるものではない。また、正孔注入材料に電子受容物質を、電子注入材料に電子供与性物質を添加することにより増感させることもできる。

前記含窒素五員環誘導体としては、例えば、オキサゾール、チアゾール、オキサジアゾール、チアジアゾール、トリアゾール誘導体が好ましく挙げられる。
特に、本発明の有機EL素子においては、前記含窒素五員誘導体として、下記式(1)~(3)のいずれかで表されるベンゾイミダゾール誘導体が好ましい。

また、本発明により得られた有機EL素子の、温度、湿度、雰囲気等に対する安定性の向上の観点から、素子の表面に保護層を設けることや、シリコンオイル、樹脂などにより素子全体を保護することも可能である。
各層の膜厚は特に限定されるものではなく、有機EL素子として適切な膜厚になるように設定すればよい。膜厚が厚すぎると、一定の光出力を得るために大きな印加電圧が必要になり効率が悪くなる。膜厚が薄すぎるとピンホール等が発生して、電界を印加しても充分な発光輝度が得られない。通常の膜厚は5nm~10μmの範囲が適しているが、10nm~0.2μmの範囲がより好ましい。
このような湿式成膜法に適した溶液として、有機EL材料として本発明の芳香族アミン誘導体と溶媒とを含有する有機EL材料含有溶液を用いることができる。また、いずれの有機薄膜層においても、成膜性向上、膜のピンホール防止などのため適切な樹脂や添加剤を使用してもよい。該樹脂としては、ポリスチレン、ポリカーボネート、ポリアリレート、ポリエステル、ポリアミド、ポリウレタン、ポリスルホン、ポリメチルメタクリレート、ポリメチルアクリレート、セルロースなどの絶縁性樹脂及びそれらの共重合体、ポリ-N-ビニルカルバゾール、ポリシランなどの光導電性樹脂、ポリチオフェン、ポリピロールなどの導電性樹脂が挙げられる。また、添加剤としては、酸化防止剤、紫外線吸収剤、可塑剤などが挙げられる。
以上例示した各種材料及び層形成方法により陽極、発光層、必要に応じて正孔注入・輸送層、及び必要に応じて電子注入・輸送層を形成し、さらに陰極を形成することにより有機エレクトロルミネッセンス素子を作製することができる。また陰極から陽極へ、前記と逆の順序で有機エレクトロルミネッセンス素子を作製することもできる。
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エレクトロルミネッセンス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など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法など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など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などにより異なるが、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。
なお、発光層、電子注入層、及び陰極は、任意の方法で形成すればよく、特に限定されない。形成方法の例には、真空蒸着法、イオン化蒸着法、溶液塗布法(例えば、スピンコート法、キャスト法、デイップコート法、バーコート法、ロールコート法、ラングミュア・ブロジェット法、インクジェット法)などが含まれる。
