phosphorescence (red) of comparable intensity, which could be used for ratiometric luminescent sensing. Solution‐processed organic light‐emitting diodes (OLEDs) based on 1 d showed a stable yellow emission with an external quantum efficiency (EQE) and luminance up to 4.79 % and 1400 cd m−2 respectively. These tungsten(VI) complexes were also applied in light‐induced aerobic oxidation reactions.
描述了两个系列的空气稳定的发光钨(VI)配合物的合成,激发态动力学及其应用。这些钨(VI)络合物在固态和溶液中显示磷光,在室温下薄膜的发射量子产率高达22%(在mCP中为5%)。包含5,7-二苯基-8-羟基喹啉酸酯配体的复合物2 c显示出强度相当的快速荧光(蓝绿色)和磷光(红色),可用于比率式发光传感。基于1 d的溶液处理有机发光二极管(OLED)显示稳定的黄色发射,具有外部量子效率(EQE),亮度高达4.79%和1400 cd m -2分别。这些钨(VI)配合物也用于光诱导的需氧氧化反应。
