Simple is good! Based on biphenyl molecules, two bipolar host materials with high triplet energies have been rationally designed, synthesized, and fully characterized. Deep blue phosphorescent organic light‐emitting diodes, which employ the new hosts and an iridium(III) complex as triplet emitter, show a maximum current efficiency of 40 cd A−1, a maximum power efficiency of 36 lm W−1, and a maximum
简单就是好!基于联苯分子,已经合理地设计,合成并充分表征了具有高三重态能量的两种双极性主体材料。深蓝色磷光有机发光二极管采用了新的主体和铱(III)配合物作为三重态发射极,其最大电流效率为40 cd A -1,最大功率效率为36 lm W -1,并且最大外部量子效率为19.5%。
