Materials with small singlet-triplet splits (ΔEST s) are introduced as sensitizing hosts to excite fluorescent dopants, breaking the trade-off between small ΔEST and high radiative decay rates. A highly efficient orange-fluorescent organic light-emitting diode (OLED) is prepared, showing a maximum external quantum efficiency of 12.2%.
具有小单重-三重态能隙(ΔEST s)的材料被引入作为敏化主体来激发荧光掺杂剂,打破了小ΔEST 和高辐射衰减率之间的权衡。制备了一种高效的橙色荧光有机发光二极管(OLED),最大外量子效率为 12.2%。
