蓝光有机电致磷光材料铱金属配合物及其制备方法和有机电致发光器件
摘要：
本发明公开了一种蓝光有机电致磷光材料铱金属配合物及其制备方法和有机电致发光器件；该材料的结构通式如下：其中，R为氢原子，C1～C20的直链或支链烷基，或C1～C20的直链或支链烷氧基。本发明提供的蓝光有机电致磷光材料铱金属配合物，2-(4’,6’-二氟-5’-(6’’-(咔唑-N-基)正己基)苯基)吡啶为环金属主配体，以2-吡啶甲酰为辅助配体，合成一种蓝光有机电致磷光材料铱金属配合物，并通过对环金属配体2-(4’,6’-二氟-5’-(6’’-(咔唑-N-基)正己基)苯基)吡啶的化学修饰实现对材料发光颜色的调节，从而获得发光波长更蓝的磷光发射。
摘要（英）：

The invention discloses a blue organic electrophosphorescent material iridium complex and its preparation method and an organic electroluminescent device. The blue organic electrophosphorescent material iridium complex has a general structural formula shown in the description. In the general structural formula, R represents hydrogen atom, or C1-C20 straight chain or branched chain alkyl, or C1-C20 straight chain or branched chain alkoxyl. 2-(4',6'-difluoro-5'-(6''-(carbazolyl-N-yl)n-hexyl)phenyl)pyridine as a ring metal main ligand and 2-pyridylformyl as an auxiliary ligand are synthesized into the blue organic electroluminescent material iridium complex. Through chemical modification of the 2-(4',6'-difluoro-5'-(6''-(carbazolyl-N-yl)n-hexyl)phenyl)pyridine as a ring metal main ligand, material luminescence color adjustment is realized and emission of phosphorescence with more blue light wavelength is realized.
