synthesized as high triplet energy host materials for green and blue phosphorescent organic light-emitting diodes. High triplet energies of 2.71 eV and 2.84 eV were obtained for ZnOx2 and ZnIm2, respectively. Green and blue phosphorescent devices were fabricated using the ZnOx2 and ZnIm2 host materials and high quantum efficiencies of 23.5% and 20.1% were achieved in green and blue devices, respectively
合成了两种锌络合物,高(2-(2-(恶唑-2-基)酚盐)锌(ZnOx2)和双(2-(1-(甲基-1H-咪唑-2-基)酚盐)锌(ZnIm2)用于绿色和蓝色磷光有机发光二极管的三重态能量主体材料。ZnOx2和ZnIm2的高三重态能量分别为2.71 eV和2.84 eV。使用ZnOx2和ZnIm2主体材料制造了绿色和蓝色磷光器件,在绿色和蓝色器件中分别实现了23.5%和20.1%的高量子效率。
