A novel beta-diketone with an electro-transporting oxadiazole group, 1-(4'-(5-(4-methylphenyl)-1,3,4-oxadiazol-2-yl)biphenyl-4-yl)-4,4,4-trifluorobutane-1,3-dione (MPBDTFA), was prepared with high yield. With this synthesized ligand as the first ligand and 1,10-phenanthroline (Phen) as the secondary ligand, a new europium(III) ternary complex, Eu(MPBDTFA)(3)Phen, was synthesized. The new beta-diketone
具有电输送的恶二唑基团的新型β-二酮,1-(4'-(5-(4-甲基苯基)-1,3,4-恶二唑-2-基)联苯-4-基)-4,4高产率地制备了1,4-三氟丁烷-1,3-二酮(MPBDTFA)。以该合成的配体为第一配体,以1,10-菲咯啉(Phen)为第二配体,合成了一种新的((III)三元络合物Eu(MPBDTFA)(3)Phen。新的β-二酮及其euro(III)三元配合物的特征在于元素分析,热重分析,红外光谱和紫外可见光谱。光致发光测量表明,有机配体吸收的能量被有效转移到中心Eu(3+)离子,并且由于(5)D(0)->(7)F,该配合物显示出强烈的特征性红色发射(j)中心Eu(3+)离子的跃迁。
