摘　　要：以4-氨基苯乙酮和苯甲酸甲酯为原料,通过酰胺化反应和克莱森缩合反应一步合成了一种具有酰胺基团的β-二酮结构的化合物[N-(4-(3-氧代-3-苯基丙酰基)苯基)苯甲酰胺],并通过1 H-NMR、IR、UV等方式对其结构进行表征。将该新型β-二酮单体与邻菲罗啉、稀土金属铕离子合成新的铕三元配合物光致发光材料,并对配合物结构和性能进行测试表征。荧光测试结果表明,由于合成的配合物共轭体系刚性更大,结构更加稳定,从而大大降低了配合物的发光能量损失,提高了配合物的发光效率,使得其形成的配合物荧光强度增强。A compound ofβ-diketone structure having an amide group named N-(4-(3-oxo-3-phenylpropanoyl)phenyl)benzamide was synthesized through the amidation reaction and claisen condensation reaction.4-aminoacetophenone and methyl benzoate were used as the main raw materials in one step.The structure of this compound was characterized by 1 H-NMR,IR and UV-visible.A new ternary complex of Eu3+were synthesized with the compound ofβ-diketones and phenanthroline.The structure and properties of the complex were characterized by IR,UV-visible and fluorescence emission spectrometry.Results of fluorescence test shown that the conjugated system of the synthesized complex was more rigid and more stable,which greatly reduced the loss of luminescence energy of the complex,improved the luminous efficiency of the complex,and enhanced the fluorescence intensity of the complex formed.
