A narrowband blue CP-TADF emitter with a rigid hetero-helicene structure (QAO-PhCz) was synthesized and characterized. QAO-PhCz exhibits good electroluminescence performance (EQE = 14.0%) and narrow FWHM. The enantiomers of QAO-PhCz display CPL and CPEL properties with || and ||values of up to 1.1 × 10 and 1.5 × 10, respectively.
合成并表征了一种具有刚性杂并苯结构的窄带蓝色热活化延迟荧光（CP-TADF）发光体（QAO-PhCz）。QAO-PhCz表现出良好的电致发光性能（外量子效率EQE = 14.0%）和窄的半高宽（FWHM）。QAO-PhCz的对映体分别表现出圆偏振发光（CPL）和圆偏振电致发光（CPEL）特性，其||和||值分别高达1.1×10和1.5×10。
