摘要: 以2-(3-(2',4'-二氟苯基)苯基)吡啶(Hdfbppy)为环金属C^N配体,乙酰丙酮(Hacac)为辅助配体,设计合成了一种绿色磷光铱配合物(Ir(dfbppy)₂(acac));研究了此配合物的光物理性质及其电致发光器件性能。室温下,配合物Ir(dfbppy)₂(acac)的二氯甲烷溶液的最大发射波长为520nm,量子效率为71%,寿命为381ns。将此配合物掺杂在4,4'-N,N'-二咔唑基二联苯(CBP)中,作为发光层制备了有机发光二极管器件。结果显示,该器件在7.2V电压下呈现的最大亮度为68324cd·m^-2,最大电流效率约为53cd·A^-1,最大功率效率为37lm·W^-1,色坐标为(0.33,0.62)。

Abstract: A green-light emitting iridium(Ⅱ) complex Ir(dfbppy)₂(acac) with 2-(3-(2',4'-difluorophenyl)phenyl)pyridine (Hdfbppy) as C^N ligands and 2,4-pentanedione (Hacac) as an ancillary ligand was designed and synthesized for phosphorescent organic light emitting diodes, and its photophysical and electroluminescent properties were investigated. The title complex exhibits a peak emission at 520 nm, a high PL quantum yield of 71%, and a relatively short phosphorescence emission lifetime of 381 ns in CH₂Cl₂ at room temperature. An organic light-emitting diode using this complex with 4,4'-N,N'-dicarbazolylbiphenyl (CBP) as the host shows a green color with CIE coordinates of (0.33, 0.62), accompanied by a rather excellent performance with a maximum luminance of 68324 cd·m^-2 at 7.2 V, the luminous and power efficiencies are 53 cd·A^-1 and 37 lm·W^-1, respectively.
