Luminescent copper(I) complexes showing thermally activated delayed fluorescence (TADF) have developed to attractive emitter materials for organic light emitting diodes (OLEDs). Here, we study the brightly luminescent dimer CuCl(P∩N) (P∩N = diphenylphosphanyl-6-methyl-pyridine), which shows both TADF and phosphorescence at ambient temperature. A solution-processed OLED with a device structure ITO/PEDOT:PSS/PYD2: CuCl(P∩N)/DPEPO (10 nm)/TPBi (40 nm)/LiF (1.2 nm)/Al (100 nm) shows warm white emission with moderate external quantum efficiency (EQE). Methods for EQE increase strategies are discussed.
具有热激活延迟荧光（TADF）的发光铜（I）配合物已发展成为有机发光二极管（OLED）有吸引力的发光材料。在此，我们研究了明亮发光的二聚体CuCl（P̂N）（P̂N = 二苯基膦基-6-甲基吡啶），其在室温下同时表现出TADF和磷光。具有ITO/PEDOT:PSS/PYD2:CuCl（P̂N）/DPEPO（10纳米）/TPBi（40纳米）/LiF（1.2纳米）/Al（100纳米）器件结构的溶液处理OLED呈现出具有适度外量子效率（EQE）的暖白色发射。讨论了提高EQE的策略方法。
