Blue organic light-emitting diodes with non-doped emissive layer (EML) structures have been garnered increasing interest due to their convenience of manufacturing process. For this purpose, we designed and synthesized two novel anthracene derivatives, PO2PhAnTz and PO2PhAnBI. Both derivatives exhibited bright blue electroluminescence emission and a relatively low operating voltage with a simple bilayer
具有非掺杂发射层(EML)结构的蓝色有机发光二极管由于其制造工艺的便利性而受到越来越多的关注。为此,我们设计并合成了两种新型蒽衍生物PO2PhAnTz和PO2PhAnBI。两种衍生物都表现出明亮的蓝色电致发光发射和相对较低的工作电压以及简单的双层器件结构。以三苯基氧化膦部分为主体、蒽核为掺杂剂、苯并咪唑为电子传输基团的PO2PhAnBI实现了平衡双极传输,并获得了5.74%的最大外量子效率。这些发现揭示了分子设计在高效非掺杂蓝色 OLED 中的作用。
