摘要 以水杨醛苯甲酰腙为配体(H2L),采用溶剂热法,合成了钇(Ⅲ)配合物Y4(HL)8O2·8(H2O)。通过红外光谱、热重分析、元素分析、紫外及荧光光谱对其进行了表征,并用X-单晶衍射测定了钇(Ⅲ)配合物的结构。其结构以四个对称的金属核为骨架,每个金属核上带有两个配体,属于四方晶系,P4/ncc空间群,a=2.1656(2)nm,b=2.1656(2)nm,c=2.6668(4)nm,α=90°,β=90°,γ=90°,V=12.507(3)nm3,Z=16。荧光光谱分析表明:钇(Ⅲ)配合物在473nm处有强蓝色荧光发射,色坐标为(0.153,0.276)。其光致发光性能较好,有望在蓝色光学材料方面得到应用。 Yttrium(Ⅲ) complex Y4(HL)8O2·8(H20) with the Schiff base ligands H2L.Salicylaldehyde Benzoyl Hydrazone was synthesized by solvothermal method, and then characterized by IR, TGA, elemental analysis, UV-Vis and PL. The crystal structure of the yttrium( Ⅲ ) complex was determined by Single-crystal X-ray diffraction. The structure of the complex is based on four symmetrical metal centers. Each metal center is coordinated with two ligands. The overall crystal structure belongs to tetragonal system represented by P4/ ncc space group, a = 2. 1656 (2) nm, b = 2. 1656 (2) nm, c = 2. 6668 (4) nm, a = 90°, β= 90°, γ =90°, V=12.5 07(3)nm3 , Z= 16. Fluorescence luminescent investigation reveals that the yttrium (llI ) complex exhibits a strong blue fluorescence emission of 473 nm with Commission Internationale de L' Eclairage (CIE) coordinates of (0. 1531, 0. 2761). The complex shows an excellent photoluminescence and can be useful as a blue optical material.
