本発明のコポリマーP1〜P8と比較例のポリマーV1とV2が、以下のモノマー(パーセントデータ=モル%)を使用するWO03/048225 A2にしたがうスズキカップリングにより合成される。
発光層(EML)中でエミッターとして使用される三重項エミッターTEG1の構造。トルエン中のTEG1のフォトルミネセンススペクトルが記録され、491.65nm(2.52eV)で最小値を、512.4nm(2.42eV)で最大値を示す。
OLEDでの使用のための適切な材料を開発するために、エネルギー準位、特に、種々の物質の励起三重項状態のHOMOおよびLUMO準位の予測が重要である。
有機機能性材料のHOMOおよびLUMO位置と三重項/一重項の準位が、量子化学計算により決定される。このために「Gaussian 03W」プログラムパッケージ(Gaussian Inc.)が使用される。金属のない有機物質を計算するために、まず、ジオメトリー最適化が、「Ground State/Semi-empirical/ Default spin/AM1」半経験法を使用して実行される(電荷0/一重項スピン)。これは、最適化ジオメトリーを基礎としたエネルギー計算に続かれる。「6-31G(d)」基本セットをもつ「TD-SCF/DFT/ Default Spin/B3PW91」法が、ここで使用される(電荷0/一重項スピン)。有機金属化合物に対しては、ジオメトリー計算は、「Ground State/Hartree-Fock/ Default Spin/LanL2MB」を介して最適化される(電荷0/一重項スピン)。エネルギー計算は「LanL2DZ」基本セット(pseudo=LanL2)が金属原子のために使用され、「6-31G(d)」基本セットがリガンドのために使用されるという相違の他は上記記載のとおりの有機物質と同様に実行される。最も重要な結果は、HOMO/LUMO準位と三重項と一重項励起状態のためのエネルギーである。第1の一重項と励起一重項/三重項状態が最も重要であり、S1およびT1準位として知られる。エネルギー計算は、ハートリー単位でHOMO HEhまたはLUMO LEhを得る。電子ボルトでのHOMOおよびLUMO値は、以下のとおりそこから計算され、ここで、これらの関係は、サイクリックボルタンメトリ測定を参照して較正から生じる:
HOMO(eV)=((HEh*27.212)−0.9899)/1.1206
LUMO(eV)=((LEh*27.212)−2.0041)/1.385
これらの値は、本願の意味で、材料のHOMO準位またはLUMO準位のエネルギー位置とみなされるべきである。例として、−0.20435ハートリーのHOMOと−0.06350ハートリーのLUMOが、化合物TMM1に対して計算から得られ(表1参照。)、較正された−5.85eVのHOMOと較正された−2.70eVのLUMOに対応する。
先行技術にしたがって、ITO/PEDOT/中間層/EML/カソードの構造を有するOLED1〜OLED4が、表2に要約されるとおりの対応する溶液を使用して、次の手順にしたがって製造される:
1)PEDOT(Baytron P AI 4083)がITOで被覆されたガラス基板上に、スピンコートにより80nmの厚さを有するバファー層として堆積され、次いで、180℃で10分間加熱される;
2)20nmの中間層(IL)が、グローブ箱中で0.5重量%の濃度を有するトルエン溶液から、スピンコートによりその上に堆積される;
3)中間層は、180℃で1時間グローブ箱中で加熱される;
4)発光層(EML)が、80nmの厚さを有する層を製造するために、適切な濃度を有するトルエン溶液から、スピンコートにより堆積される;
5)得られた素子は、残留溶媒を除去するために、グローブ箱中で加熱される;
6)Ba/Alカソードが、厚さ3nm/150nmを有する発光層上に気相堆積により堆積される;
7)素子は封入される。
こうして得られたOLED、OLED1〜OLED6、Ref.1およびRef.2は、標準方法により特性決定される。ここで、以下の特性が測定される:VIL特性、エレクトロルミネッセンススペクトル、色座標、効率、駆動電圧および寿命。
こうして得られたOLED、OLED7〜OLED11およびRef.1は、標準方法により特性決定される。ここで、以下の特性が測定される:VIL特性、エレクトロルミネッセンススペクトル、色座標、効率、駆動電圧および寿命。
