Better Constructions: By inserting anthracene core in the deep-blue building block, two D-π-A fluorescent blue emitters, ICz-An-PPI and IP-An-PPI were designed and synthesized. Impressively, the doped deep-blue OLED based on IP-An-PPI exhibited excellent performances with an unexpectedly high EQE of 7.5 % with the CIE coordinate of (0.150, 0.118), which is one of the best among the state-of-the-art deep-blue OLEDs with the CIE_y <0.12.

基于蒽衍生物构建外部量子效率高达 7.5% 的高效蓝色 OLED

更好的结构：通过在深蓝色构建块中插入蒽核，设计并合成了两种 D-π-A 荧光蓝色发射体ICz-An-PPI和IP-An-PPI。令人印象深刻的是，基于IP-An-PPI的掺杂深蓝色 OLED表现出优异的性能，出乎意料地高 EQE 为 7.5%，CIE 坐标为 (0.150, 0.118)，是目前最先进的有机发光二极管之一。 -CIE _y <0.12 的深蓝色 OLED 。
