摘要
Abstract Novel accessible scaffold featuring circularly‐polarized room‐temperature phosphorescence (RTP) is attractive but challenging. Herein, we report a new feasibly separable bidibenzo[ b , d ]furan compound with strong circularly‐polarized RTP when doping into the rigid polymer matrix. The simple silica‐gel column can separate the absolute chiral R ‐isomer with excellent chiroptical properties. The experimental data reveal that the treated films exhibit an RTP efficiency of 14.8 %, a largest dissymmetric factor of 0.12, and a longest lifetime of 0.56 s under ambient conditions. It is found that reducing the nonradiative decays boosts the intrinsic circularly‐polarized RTP emission. The impressive results indicate that the locked axial chirality skeleton endows the potential of achieving superior circularly‐polarized emission for the small organic optoelectronic molecules.
