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%.
这项工作描述了第一种通过手性扰动实现圆偏振发光的热激活延迟荧光材料。通过在室温下采用可扩展的一锅法连续合成程序获得的这些新分子结构（产率83%）显示出高量子产率（高达74%）以及圆偏振发光，其绝对发光不对称因子|glum|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，该二极管表现出高达9.1%的外量子效率。
