Got the blues: High‐triplet‐energy bipolar host materials based on a bipolar N,N‐diphenylpyridin‐4‐amine (DPPA) core structure were developed for blue phosphorescent organic light‐emitting diodes (PHOLEDs). Two DPPA‐based host materials (see picture) showed high triplet energy over 2.70 eV and a high quantum efficiency of 15.6 %.
忧郁:基于双极性N,N-二苯基吡啶-4-胺(DPPA)核心结构的高三重态能量双极性主体材料已开发用于蓝色磷光有机发光二极管(PHOLED)。两种基于DPPA的基质材料(见图)显示出超过2.70 eV的高三重态能量和15.6%的高量子效率。
