以 4 正辛烷氧基二苯甲酰甲烷 (ODBM)为配体 ,邻菲 只罗啉为第二配体与铕配位 ,合成了一种新的铕 长链烷氧基 β二酮 邻菲 只罗啉三元配合物。用红外光谱、核磁共振谱和元素分析对配体和配合物的结构进行了表征 ,并研究了配合物三氯甲烷溶液和薄膜的光致发光性能。结果表明 ,这种配合物的三氯甲烷溶液在浓度为 1 0 - 2 ～ 1 0 - 4 mol/L范围内浓度淬灭现象不显著 ,溶液和薄膜的荧光都强于铕 二苯甲酰甲烷 邻菲只罗啉配合物。
A novel europium long-chain alkoxy β-diketone orthophosphate was synthesized with 4-octyloxy dibenzoylmethane (ODBM) as the ligand and o-phenanthroline as the second ligand to europium Phenanthroline ternary complexes. The structures of the ligands and complexes were characterized by FTIR, 1HNMR and elemental analysis. The photoluminescence properties of the complexes were also studied. The results showed that the quenching of the chloroform solution of this complex was not significant at concentration range of 1 0 - 2 ~ 1 0 - 4 mol / L, and the fluorescence of the solution and the thin film was stronger than that of europium dibenzoylmethane Phenanthroline only compound.
