1.蛍光またはリン光発光体のマトリックス材料として用いられる、本発明による化合物は、高効率および長寿命をもたらす。これは特に、化合物をリン光発光体のマトリックス材料として用いる場合に当てはまる。
他に指示しない限り、下記の合成は保護ガス雰囲気下、乾燥溶媒中で実施される。溶媒および試薬は、例えばSigma−ALDRICHまたはABCRから購入することができる。使用する出発材料は例えばフェナジンである。文献から公知の出発材料の場合の括弧内の番号はCAS番号に関する。
本発明によるOLEDおよび従来技術によるOLEDを、本明細書に記載した詳細(層の厚さの変化、材料)に適合させ、WO 2004/058911による一般的プロセスによって製造する。
本発明による化合物3fを、緑色ドーパンドTEG1を含むOLEDの正孔輸送材料として、従来技術による類似の化合物H3の代わりに使用する場合、実質的に20%良好な出力効率が得られる(例V1およびE5)。
緑色リン光ドーパントを含むOLEDのマトリックス(ホスト)として2種の材料を使用することは、単一材料を使用する場合よりも良好な性能データを頻繁にもたらす。それが、材料が本出願にとって非常に関心がある理由である。とりわけ、置換基として硫黄または酸素含有ヘテロ芳香族環系を含む本発明による材料が、ここでは従来技術によるトリアジン含有材料に比べて区別される。より良好な量子および出力効率(例V2、V3、E6、E7、およびE8)が得られる。さらに、寿命がかなり改善される。光束密度は、その初期値10000cd/cm2から、定電流密度での動作で、例V2およびV3についてそれぞれ160時間および180時間以内に70%まで低下するが、これは例E6、E7およびE8においてはそれぞれ300時間、245時間および230時間を要する。
