Synthesis and Photoelectric Properties of Bipolar Host Material 9-phenyl-3-(phenylsulfonyl)-6-(triphenylsilyl)-9H-carbazole

设计开发了一种新的双极性蓝色磷光主体材料,将其搭配Firpic应用于简单器件结构,通过调整器件中载流子传输层的厚度得到了比较满意的结果:最大电流效率40 cd/A,最大亮度19 691 cd/m2,最大流明效率12 lm/W。这一结果说明所开发的主体材料能够很好的平衡载流子的注入与传输能力,具有适宜的三线态能量和良好的热稳定性,是一种优良的蓝色磷光主体材料。

A new bipolar blue phosphorescent host material was synthsized and applied to phosphorescent organic light emitting diodes with Firpic（iridium（Ⅲ）[bis（4,6-difluorophenyl）-pyridinato-N,C2′]picolinate）,the maximum current efficiency was 40 cd/A,maximum brightness was 19 691 cd/m2,maximum luminous efficiency was 12 lm/W.The results suggest that the host materials which we synthesized can better balance carrier injection and transport with appropriate triplet energy and goodly thermal stability.
