混合物とドープ材料
式の化合物は、上に述べたとおりであり、一連の材料で、一連の目的で混合され、またはドープされてよい。
R2とR3は、一緒になって、C1-C4アルキル、アルコキシ或いはシアノで置換されてもよい、1〜5環状アリール(ポリ環状を含む)、アラルキル若しくはヘテロアリール基を形成し、
R4は、水素、C1-C4アルキル或いはアリールであり、及び
Arは、1以上のC1-C4アルキル或いはアルコキシ基で置換されてよい、単環状、二環状或いは三環状アリール若しくはヘテロアリールまたはそれらのオリゴマーである。好ましい亜属は、式
本発明のOLEDは、とりわけ、フラットパネルディスプレーに有益であり、典型的には、陽極と陰極とその間に挟まれたエレクトロルミネッセンス層、電子注入及び/又は輸送層、正孔注入及び/又は輸送層及び随意に補助的層を含む多様な薄層を含む。層は、典型的には連続的真空気相堆積操作により構築されるが、1以上の層、例えば、正孔注入及び正孔輸送層を他の方法、例えば、スピンコート或いはインクジェット印刷により形成することが都合がよいかもしれない。
多くの具体例で、陽極は、ガラス或いは他の透明基板上に被覆された錫酸化物或いはインジウム錫酸化物の層により形成される。使用されてもよい他の材料は、アンチモン錫酸化物とインジウム亜鉛酸化物を含む。基板に関しては、硬質或いは軟質透明プラスチック材料、好ましくは、寸法的に安定で、比較的高いTgの水(水蒸気を含む)不透過性である材料が使用されてよい。PENが好ましい材料であるが、使用されてよい他の材料は、PES、PEEKとPETを含む。プラスチックは電導性フィルムで被覆されてよく、耐湿性を改善し、それゆえ使用寿命を改善するためにバリア被覆を有してもよい。
単一の層が、陽極とエレクトロルミネッセンス材料との間に設けられてもよいが、多くの具体例では、少なくとも二つの層が存在し、その一つは、正孔注入層(バッファー層)であり、他方は、正孔輸送層であり、二つの層構造は、いくつかの具体例では、改善された安定性と素子寿命を与える(US-A-4720432 (VanSlyke et al., Kodak)参照。)。正孔注入層は、引き続く有機層の膜形成特性を改善し、正孔輸送層中への正孔の注入を容易にすることに役立ち得る。
使用され得る正孔輸送層は、好ましくは、20〜200nmの厚さを有する。

任意の既知の電子注入材料が使用されてよく、LiFが典型的である。他に可能なものは、BaF2、CaF2及びCsF2を含む。
多くの具体例では、アルミニウムが、それ自身か、マグネシウム或いは銀のような元素と合金化されて、陰極として使用されるが、いくつかの具体例では、他の陰極金属、例えば、カルシウムが使用されてよい。一つの具体例では、陰極は、電子注入層或いは電子輸送層に、より近接する、第1の合金層、例えば、Li-Ag、Mg-Ag或いはAl-Mgと、電子注入或いは電子輸送層から更に離れた純粋なアルミニウムの第2層を含み得る。陰極材料は、ガラスから成り得るか、硬質或いは軟質であってよく、随意に透明であってよいプラスチックから成りなり得る透明板状材料上に存在してもよい。プラスチック基板については、硬質或いは軟質透明プラスチック材料、好ましくは、比較的高いTgを有する寸法的に安定で、水(水蒸気を含む)不透過性である材料が使用され得る。PENが好ましい材料であるが、使用されてもよい他の材料は、PES、PEEKとPETを含む。プラスチックは電導性フィルムで被覆されてよく、作業条件下で遭遇し得る湿気、例えば、雰囲気水蒸気に対する抵抗性を改善するためにバリア被覆を有してもよい。
予めエッチングされたITO被覆ガラス片(10×10cm2)が使用された。素子はSolciet Machine, ULVAC Ltd. Chigacki,日本、を使用する真空蒸着により、ITO上に連続的に層を形成することにより製造された。各画素の活性領域は、3mm×3mmであった。被覆された電極は、ガラス背板を使用してUV硬化接着剤で不活性雰囲気(窒素)中に封入された。エレクトロルミネッセンスの調査が、正端子に常に接続したITO電極により実行された。電流対電圧の調査が、コンピューター制御されたKeithly 2400 source meterにより実行された。
陽極層、バッファー層、正孔輸送層、エレクトロルミネッセンス層(ドープされた材料)、電子輸送層、電子注入層と陰極層から成る、赤色及び青緑色発光を有する素子が、上記方法により形成された。膜厚は、nmである。
