| 中文摘要 | with the aim of endowing triplet emitters in the development of organic light-emitting devices (oleds) with electron-injection/-transporting (ei/et) features, the phenylsulfonyl moiety was introduced into the phenyl ring of a 2-phenylpyridine (hppy) ligand and the yellow phosphorescent heteroleptic iridium(iii) complex 1 was developed. it was shown that the so(2)ph unit could provide ei/et character to 1, as indicated from both electrochemical and computational data. complex 1 is a promising yellow-emitting material for both monochromatic oleds and white oleds (woleds). the outstanding electronic traits associated with 1, coupled with careful device design, afforded very attractive electroluminescent performances for two-element woleds, including a low turn-on voltage of less than 3.7 v, a maximum brightness of 48000 cd m(-2), an external quantum efficiency of 13.0 %, a luminance efficiency of 34.7 cd a(-1), and a power efficiency of 24.3 lm w(-1). in addition, a good color rendering index (cri) of about 74, a stable white color with a commission internationale de l'eclairage (cie(x,y)) variation of delta(x, y)< +/- (0.02, 0.02), and a correlated color temperature higher than 5130 k were obtained. these encouraging results indicate the potential of these woleds as good candidates for warm indoor lighting sources, as well as the critical contribution of such key ei/et properties to triplet emitters to advance new oled research. |
