【摘要】 合成了一种含联吡啶和口恶二唑基团的新颖配合物Eu(DBM)3L(DBM为二苯甲酰甲烷;L为4,4′-二对甲基苯基-1,3,4-口恶二唑-2,2′联吡啶),通过元素分析、红外光谱、紫外光谱、1H NMR、荧光光谱对其进行了表征。配合物的发射光谱表现出较强的三价铕离子的特征发射,以其为发光层制备了电致发光器件,对其发光性能进行了研究。更多还原

【Abstract】 A novel europium complex,Eu(DBM)3L [DBM=dibenzoyl methane,L= 4,4′bis(4-methyphenyl-1,3,4-oxadiazole)-2,2′-bipyridine] functionalized by carbazole and bipyridine fragments,was synthesized and characterized by elemental analysis,IR,UV,1H NMR and fluorescence spectrum.It could be found that the emission spectra at 612 nm was attributed to the Eu3+ ion characteristic spectrum.It was used as emitting material in organic electroluminescent devices.The electroluminescent properties were also studied.更多还原
