<b>Enhancing Circularly Polarized Electroluminescence through Energy Transfer within a Chiral Polymer Host</b>

Blends of a CP-TADF small molecule ((R)-BN-MDPA) and a chiral polymer (cPF8PhO8) are presented. Energy transfer from cPF8PhO8 to (R)-BN-MDPA is observed. gPL observed for (R)-BN-MDPA is substantially enhanced when blended in the chiral polymer host and a state-of-the-art gEL of 0.091 is demonstrated.本研究报道了圆偏振热活化延迟荧光（Circularly Polarized Thermally Activated Delayed Fluorescence, CP-TADF）小分子((R)-BN-MDPA)与手性聚合物(cPF8PhO8)的共混体系。实验观测到能量从手性聚合物主体cPF8PhO8向(R)-BN-MDPA转移。当(R)-BN-MDPA掺杂于该手性聚合物基质中时，其光致圆偏振发光不对称因子（gPL）得到显著增强，同时实现了0.091的顶尖级电致圆偏振发光不对称因子（gEL）。
