Description
1.寿命は、ほとんどの場合に、あまりにも短すぎ、これは、長寿命を有するOLEDの市場への導入の妨げとなっている。
2.効率は、しばしば、輝度の向上に伴い相当に低下することが、効率/輝度曲線から明らかである。このことは、実際には必要である非常に高い輝度は、高いパワー消費によってのみ得ることができるということを意味する。しかしながら、大きなパワー消費は、携帯用の装置(携帯電話、ラップトップ等)について高いバッテリーパワーを要求する。加えて、大部分が熱に変換される大きなパワー消費は、ディスプレイに熱的な損傷をもたらし得る。
一方で、例えば、電子輸送材料として用いられるAIQ3およびZnQ2のようなものは、水を付加する傾向を有する。
これらの、および同様のアルミニウムおよび亜鉛錯体の高い吸湿性は、重大な実用上の不利な点である。標準状態下で合成し貯蔵するAIQ3も、ヒドロキシキノリン配位子に加えて、錯体分子につき1モルの水を常に含有する(例えば、H.シュミットバウア(Schmidbaur)等、Z.Naturforsch., 1991, 46b, 901-911 を参照のこと)。この水は、除去することが非常に難しい。OLEDにおける使用のために、AIQ3およびZnQ2は、従って、複雑な、多工程の昇華プロセスにおける複雑な精製に供されなければならず、続いて、水を排除しながら保護ガス雰囲気下で貯蔵し取り扱わなければならない。さらに、個々のAIQ3のバッチの品質の大きなばらつき、および乏しい貯蔵安定性が、観察されている(S.カルク(Karg)、E−MRSコンファレンス、2000、ストラスブール)。
