抄録/ポイント： 高効率で安定な深青色有機発光ダイオード(OLED)のための純粋な有機蛍光体の分子設計は依然として課題である。国際照明委員会(CIE)座標,外部量子効率(EQE),輝度および寿命に関する優れた性能は,しばしば1つの深青OLEDで同時に達成できない。ここでは,新しいカルバゾール系熱活性化遅延蛍光発光体DPFCz-TRZを設計し,Cz-TRZのFriedel-Craftsアリールメチル化により合成した。親化合物Cz-TRZと比較して,DPFCz-TRZに基づくOLEDは,最大EQEが15.5%,輝度が16000cd/m2を超えると大幅に改善された。一方,CIE座標(0.15,0.10),λ=445nmのエレクトロルミネセンス(EL)最大値と65nmの半値全幅(FWHM)を保持した。さらに,このデバイスは,100cd/m2で1304hのLT50に対応して,500cd/m2で78hのそれぞれの寿命(LT50,初期輝度の50%までの時間)を示した。印象的に,5.2%の記録的高EQEを10000cd/m2の非常に高い輝度で得ることができた。本研究は,(≦0.15,≦0.10)の座標と16000cd/m2を超える最大輝度を有する深青純粋有機エレクトロルミネッセンスデバイスにおいて,15%EQEと1000時間LT50(100cd/m2)以上の同時達成の最初の報告を実証した。Copyright 2020 Wiley Publishing Japan K.K.
