研究了三个电子受体（A）与一个电子供体（D）结合形成的一系列蓝色激基复合物的电致发光（EL）和光致发光（PL）特性。三种激基复合物的发光范围从天蓝色到紫蓝色，虽然受体三重态能级不同，但具有相同的热激活延迟荧光特性。温度依赖性的PL衰减测量表明，长寿命的激基复合物将被严重的声子猝灭，而单体三线态猝灭效应不是低效率的起源。详细的分析表明，RISC速率可能更多地受到D/A材料的空间结构和D或A分子中的取代基的影响。研究了陷阱效应和激基复合物与黄色掺杂剂之间的能量传递。
Electroluminescence (EL) and photoluminescence (PL) characters of a series of blue exciplexes from combinations between three electron acceptors (A) and one electron donor (D) were studied. The emissions of three exciplexes, ranging from sky blue to purple blue, though with quiet different acceptor triplet levels, possess the same thermally activated delayed fluorescence character. Temperature dependence of the PL decay measurement suggests that the long-lived exciplex would be quenched heavily by phonon, while the monomer triplet quenching effect was not the origin of low efficiency. Detailed analysis indicates that the RISC rate could be more affected by the spatial structure of D/A materials and substituent group in the D or A molecules. Trap effect and energy transfer from exciplex to the yellow dopant were also studied.
