We report a systematic molecular design in BF2bdk-based afterglow emitters with photoluminescence quantum yields up to 46.3% and lifetimes around 1 s. Suitable excited-state types, diverse excited state species, relatively small singlet-triplet energy gaps and strong dipole-dipole interactions are critical in determining the afterglow properties.
我们报道了一种基于BF2bdk的余辉发光体的系统分子设计，其光致发光量子产率高达46.3%，寿命约为1秒。合适的激发态类型、多样的激发态物种、相对较小的单重态-三重态能隙以及强偶极-偶极相互作用对于确定余辉性质至关重要。
