摘要

结合圆偏振发光(CPL)为基础的有机发光二极管(cp - oled)的发射器在追求新的光电子应用，如3D显示和光数据存储是非常理想的。特别是，具有圆极化热激活延迟荧光(CP-TADF)的发射器能够在oled中实现高效率。通过进一步赋予多共振热激活延迟荧光(mr - cp - oled)圆极化特性，mr - cp - oled可以获得较窄的发射带宽，有助于实现超小带宽的目标。因此，本文综述了CP-TADF发射器的最新进展和演变，它们的升级特性和相应的器件技术，以及在实际cp - oled中遇到的挑战。

Advances in organic materials for chiral luminescence-based OLEDs

Emitters incorporating circularly polarized luminescence (CPL)-based organic light-emitting diodes (CP-OLEDs) are highly desirable in the pursuit of new optoelectronic applications such as 3D displays and optical data storage. In particular, emitters possessing circularly polarized thermally activated delayed fluorescence (CP-TADF) are able to achieve high efficiency in OLEDs. By further endowing multi-resonance thermally activated delayed fluorescence (MR-TADF, a subclass of TADF) with circularly polarized properties, MR-CP-OLEDs can obtain narrow emission bandwidths and may help to realize the holy grail of ultra-small bandwidth. Accordingly, this review covers the recent progress and evolution of CP-TADF emitters, their upgraded features and corresponding device technologies, as well as the challenges encountered in practical CP-OLEDs.
