Description
アノード、
カソード、
前記アノードおよび前記カソードの間に位置する発光層を含む有機発光デバイスにおいて、前記発光層は一般式1を有する発光金属錯体を含み、
1)9,9−ジアルキルフルオレン−2,7−ジイルのホモポリマーのような第1の繰返し単位のホモポリマーは、電子輸送を提供するために利用され得る。
2)第1の繰返し単位およびトリアリールアミン繰返し単位を含むコポリマー、特に、式46〜51から選ばれる繰返し単位は正孔輸送を提供するために利用され得る。
反応は乾燥二窒素ガス雰囲気中で行われた。
[HB(インダゾリル)3]は、ヒドロトリス(インダゾリル)ボラトリガンドを表す。
反応は水晶ガラス器を使用して行われた。
(A)ポリ(エチレンジオキシチオフェン)/ポリ(スチレンスルホネート)(PEDT/PSS)(Baytron P(登録商標)として、HC Starck of Leverkusen, Germanyから市販されている)がスピンコートによってガラス基板(Applied Films、Colorado、USAから市販されている)上に支持されたインジウム錫酸化物アノード上に堆積された。F8−TFB(下記に示す)の正孔輸送層がキシレン溶液からスピンコートによってPEDT/PSS層上に約10nmの厚さに堆積され、180℃で1時間加熱された。実施例1からの金属錯体1がPVKホスト中のキシレン溶液からスピンコートによってF8−TFB層の上に、約65nmの厚さに堆積された。ホスト材料に対する金属錯体の比率は5wt%:95wt%であった。Ba/Alカソードが、半導体ポリマー上に最大約10nmの厚さのバリウムの第1の層および最大約100nmの厚さのアルミニウムバリウムの第2の層を気相蒸着させることににより、金属錯体層上に形成された。最終的に、デバイス上に置かれたゲッターを含む金属封止を使用してデバイスは封止され、気密シールを形成するために基板上に接着された。
