A chiral chromophore with thermally activated delayed fluorescence characteristics is designed. A model describing vibrations of the dihedral angle between donor and acceptor units allowed at room temperature explains the enhanced fluorescence rate of the molecule, including a nearly 100% photoluminescence quantum yield and the absence of circularly polarized emission characteristics from enantiomers of the chromophore.
设计了一种具有热激活延迟荧光特性的手性生色团。一个描述供体和受体单元之间二面角在室温下振动的模型解释了该分子增强的荧光速率，包括近乎 100%的光致发光量子产率和手性生色团对映体没有圆偏振发射特性。
