选择阿夫苯宗作为辅助配体,合成了两种黄色Ir(III)配合物,分别命名为Irdfppyavo和Irbtavo,[dfppy,bt,avo分别代表2-(2,4-二氟苯基)吡啶、2-苯基苯并[d]噻唑和阿夫苯宗],作为黄色有机发光二极管的掺杂剂进行了深入的研究。最重要的是,亮度为100-1000cd m-2的黄色电致发光器件对irdfppyavo和irbtavo的功率效率滚降值分别为28.9%和21.4%.
Avobenzone as an ancillary ligand was chosen to construct two yellow iridium(III) complexes, named Irdfppyavo and Irbtavo, [dfppy, bt, and avo represent 2-(2,4-difluorophenyl)pyridine, 2-phenylbenzo[d]thiazole, and avobenzone, respectively], which were thoroughly investigated as yellow organic light-emitting diode dopants. Most importantly, the yellow electroluminescence devices from a luminance of 100–1000 cd m–2 displayed small power efficiency roll-off values of 28.9 and 21.4 % for Irdfppyavo and Irbtavo, respectively.
