A fully diarylmethylene-bridged triphenylamine derivative is efficiently synthesized. It has an almost planar triphenylamine (TPA) skeleton and exhibits excellent thermal and morphological stability. Devices with the novel TPA derivative as host material and Ir(ppy)(3) as triplet emitter show a maximum current efficiency of 83.5 cd/A and a maximum power efficiency of 71.4 lm/W for green electrophosphorescence.
一种完全由二芳基亚甲基桥连的三苯胺衍生物被高效合成。它具有近乎平面的三苯胺（TPA）骨架，并表现出优异的热稳定性和形态稳定性。以这种新型TPA衍生物作为主体材料、Ir(ppy)(3)作为三线态发光体的器件，在绿色电致磷光方面显示出最大电流效率为83.5 cd/A，最大功率效率为71.4 lm/W。
