Description
1.駆動寿命は、特に青色発光の場合において未だに短く、今日まで、簡単な用途を商業的に達成できているにすぎないことを意味する。
2.効率は近年改善されているが、とりわけ蛍光OLEDの場合において未だにかなり低く、改善する必要がある。
3.駆動電圧は、とりわけ蛍光OLEDの場合においてかなり高く、従って、パワー効率を改善するためにはさらに低減させる必要がある。これは、特にモバイル用途にとってより重要なことである。
4.芳香族アミンと二重結合系の双方を含む多くの青色発光エミッタは、熱的に不安定であり、昇華中または蒸着中に分解する。従って、これらの系の使用は不可能であるか、かなりの損失と高い技術的な複雑さを伴ってのみ可能である。
Aは、各々の出現について、窒素、リン、P=O、P=S、ヒ素、As=O、As=S、アンチモン、Sb=O、またはSb=Sであり、

R2は、各々の出現について同一であるか異なり、H、または1〜20個のC原子を有する脂肪族炭化水素基若しくは芳香族炭化水素基である)、並びに、
b)少なくとも1種のホスト材料1〜99.9重量%

Lは、各々の出現について同一であるか異なり、共有結合、または1、2、3、4若しくは5個の架橋原子を有する二価の架橋である)。
1.対応するデバイスの効率は、従来技術による系と比較して高くなる。
2.対応するデバイスの安定性は、従来技術による系と比較して高くなり、これは、特に、有意により長い寿命から明らかである。
3.駆動電圧は低減される。従って、パワー効率は向上する。このことは、特に、ホスフィンオキシドをホスト材料として用いる場合に当てはまる。
4.化合物は、それほどの分解を伴うことなく良好に昇華および蒸着され、従って、処理がより容易であり、よって、従来技術による材料と比べて、特に二重結合においてさらに置換されていないスチルベン単位を含有する材料と比較して、OLEDにおける使用についてより適切である。
