An ingenious strategy is for the first time proposed to develop solution-processable deep-blue HLCT emitters by attaching rigid imide aliphatic rings onto the HLCT emitting core. With outstanding characteristics of these emitters, the unprecedented OLED performances with a record-breaking efficiency of 11.5 % and high colour purity are achieved, showing competitive superiority for ultrahigh-definition
首次提出了一种巧妙的策略,通过将刚性酰亚胺脂肪族环附着到 HLCT 发射核上来开发可溶液加工的深蓝色 HLCT 发射器。凭借这些发射器的出色特性,OLED 实现了前所未有的性能,破纪录的 11.5% 效率和高色纯度,显示出超高清显示器的竞争优势。
