High-efficiency deep blue fluorescent emitters based on phenanthro[9,10-d]imidazole substituted carbazole and their applications in organic light emitting diodes
series of highly efficient deep blue emitters comprising of carbazole and phenanthro[9,10-d]imidazole moieties are designed and synthesized. These compounds present deep blue emission, narrow FWHM, high quantum yields, high thermal and morphological stabilities. Among them, the design strategy of 2:1 ratio of phenanthro[9,10-d]imidazole and carbazole unit affords M2 with more balanced carrier injection and
设计并合成了一系列由咔唑和菲[9,10-d]咪唑部分组成的高效深蓝色发射体。这些化合物呈现深蓝色发射,窄的半高宽,高量子产率,高热稳定性和形态稳定性。其中,菲咯[9,10-d]咪唑和咔唑单元的比例为2:1的设计策略使M2具有更平衡的载流子注入和传输性能。观察到使用M2作为发光层的OLED可以提供y <0.06的真正深蓝色CIE,具有3.02%的最高外部量子效率。通过充分利用这些深蓝色发射体的优势,它们还可以用作荧光和磷光染料的出色基质。基于M2 / Ir(ppy)3的高性能绿色磷光器件以33.35 cd A -1的最大电流效率,22.99 lm W -1的功率效率和9.47%的最大外部量子效率来获得λ。当用橙色荧光材料掺杂时,在仔细调整掺杂比例后,成功地以5.53 cd A -1的最大电流效率和(0.313,0.305)的CIE坐标成功地制备了两种发光成分的白色OLED 。非掺杂和掺杂器
