High-efficiency blue thermally activated delayed fluorescence (TADF) molecules, consisting of phenoxaphosphine oxide and phenoxathiin dioxide as acceptor units and 9,9-dimethylacridan as a donor unit, are reported. Maximum external electroluminescence quantum efficiencies of up to 20.5% are achieved in blue organic light-emitting diodes (OLEDs) by employing these materials as TADF emitters.
报告了一种高效的蓝色热激活延迟荧光（TADF）分子，它由苯并氧磷氧化物和苯并噻二唑二酮作为受体单元，9,9-二甲基吖啶作为供体单元组成。通过将这些材料用作 TADF 发射器，在蓝色有机发光二极管（OLED）中实现了高达 20.5%的最大外部电致发光量子效率。
