摘　　要：近年来,有机发光二极管(OLED)的急速发展源于磷光材料的商业化应用。与荧光材料相比,磷光材料的理论内量子效率提高了3倍。而铱原子的原子序数大、d轨道分裂大、性质稳定等优点使得铱(Ⅲ)配合物成为最具潜力的OLED发光材料。相比于红光和绿光发光材料,高效稳定的蓝光发光材料的开发仍然是制约OLED显示技术发展的难题。本文将蓝光铱配合物按其配位结构进行精细分类,并对每种配位构型的蓝光铱配合物的发光性质和器件性能进行了全面分析,期望为研究人员和行业专业人士后续开发具有高色纯度、高效率和长寿命的蓝光OLED提供有价值的参考和借鉴。In recent years,the rapid development of organic light-emitting diodes(OLEDs)stems from the com⁃mercial application of phosphorescent materials,which have a 3-fold increase in theoretical internal quantum effi⁃ciency compared to fluorescent materials.Iridium(Ⅲ)complexes are the most promising OLED luminescent materi⁃als due to their large atomic number,large d orbital splitting and stable properties.Compared with red and green light-emitting materials,the development of efficient and stable blue light-emitting materials is still a problem re⁃stricting the development of OLED display technology.In this paper,the blue iridium complexes are classified according to their coordination structures,and the luminescence properties and device properties of each blue iridi⁃um complex are analyzed.As a result,this comprehensive analysis provides researchers and industry professionals with a valuable resource for the development of blue OLEDs with high color purity,high efficiency and long lifetime.
