【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、1HNMR、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) 3 L [DBM=dibenzoyl methane,L=4,4′-bis(4-methy-phenyl-1,3,4-oxa diazole)-2,2′-bipyridine] function-alized by carbazole and bipyridine fra gments,was synthesized and characterized by elemental analysis,IR, UV, 1 H NMR and fluorescence spectrum.It could be found that the emission s pectra at612nm was attributed to the Eu 3+ ion characteristic spectrum.It was used as emitting material in organic electroluminescent devices.The electrolu minescent properties were also studied.更多还原
