这项工作描述了第一个热激活延迟荧光材料，使圆偏振光发射通过手性微扰。这些新的分子结构通过在室温下可扩展的一锅顺序合成程序（83%产率）获得，显示出高量子产率（高达74%）和具有绝对发光不对称因子的圆偏振发光，|闷闷不乐|，为1.3 × 10−3。这些手性分子已被用作有机发光二极管中的发光掺杂剂，其表现出高达9.1%的外量子效率。
This work describes the first thermally activated delayed fluorescence material enabling circularly polarized light emission through chiral perturbation. These new molecular architectures obtained through a scalable one-pot sequential synthetic procedure at room temperature (83% yield) display high quantum yield (up to 74%) and circularly polarized luminescence with an absolute luminescence dissymmetry factor, |glum|, of 1.3 × 10−3. These chiral molecules have been used as an emissive dopant in an organic light emitting diode exhibiting external quantum efficiency as high as 9.1%.
