设计合成了一种双核环金属铱,铂配合物二[N,N-2-(2,4-二氟苯基吡啶) C3,N1](吡啶甲酸) 合铱(Ⅲ) -C_6-[苯基吡啶-C3,N1](吡啶甲酸) 合铂(Ⅱ) (FIrPPyPt) 。通过核磁共振仪、元素分析仪、紫外-可见吸收光谱仪和光致发光光谱仪对其结构和性能进行了表征。结果表明,配合物FIrPPyPt的紫外-可见吸收位于250 ~ 450 nm之间,荧光发射峰位于465和493 nm。将配合物FIrPPyPt以质量分数1% ~ 8% 掺杂到主体材料聚乙烯基咔唑(PVK) + 2-(联苯-4-芳基) -5-(4-叔丁基苯) -1,3,4-噁二唑(PBD) (30%) 中制作了电致发光器件,在不同电压下电致发光光谱中,显现出铱配合物和铂配合物的特征峰,波峰位于400、500和530 nm蓝...

A dinuclear cyclometalated iridium-platinum complexIridium [Ⅲ] bis [( 2, 4-difluorophenyl )-pyridinato-N, C2′] [ picolinate ]-C6-Paltinum [ II ] [ phenylpyridinato-N, C2′] [ picolinate ] ( FIrPPyPt ) was designed and synthesized .Its structure and properties were characterized by NMR , elemental analyzer , UV absorption spectroscopy and photoluminescence spectroscopy .The results show that the UV absorption of the complex FIrPPyPt is located between 250 and 450 nm, and the fluorescence emission peak is located at 465 and 493 nm.The electrolu...
