虽然螺二吖啶（SBA）衍生物显示出有前途的潜力，不仅热激活延迟荧光（TADF）的发光体，而且作为主体材料的蓝色磷光发光体，只有有限的研究已在文献中报道。在这里，我们开发了一种基于SBA的主体材料mCN-SBA，其实现了具有19.8%的外量子效率和（0.16，0.23）的国际照明委员会（CIEx，y）的蓝色磷光OLED。
Although spirobiacridine (SBA) derivatives show a promising potential not only for thermally activated delayed fluorescent (TADF) emitters but also as host material for blue phosphorescent emitters, only limited research has been reported in the literature. Here, we developed an SBA-based host material, mCN-SBA, which realized a blue phosphorescent OLED with an external quantum efficiency of 19.8%, and Commission Internationale de l'Eclairage (CIEx,y) of (0.16, 0.23).
