| 摘 要： | 合成了4个新的基于多胺酚配体的Dy(Ⅲ)和Zn/Ni-Dy(Ⅲ)配合物:Dy(CH_3OCH3)L](1),Dy2(μ-H2O)L2](2),Zn2DyL2]ClO4·H2O(3)和Ni2DyL2]ClO4·H2O (4)(H3L=N,N′,N″-三(3,5-二甲基-2-羟基苯酚)-1,4,7-三氮杂环壬烷)。X射线单晶衍射分析表明,配合物1和2分别为单核和双核Dy(Ⅲ)配合物,3和4为M-Dy(Ⅲ)-M三核配合物(M=Zn (3),Ni (4))。磁性测试表明,配合物1和2具有场诱导的慢磁弛豫行为,且2具有多个磁弛豫过程,配合物3和4中没有观察到明显的慢磁弛豫行为。荧光测试表明,配合物1~3具有Dy(Ⅲ)离子典型的窄带特征发射,由于Ni(Ⅱ)离子的荧光猝灭作用,配合物4没有明显的荧光产生。

| Abstract: | Four Dy(Ⅲ)and Zn/Ni-Dy(Ⅲ)complexes with polyamine phenol ligand were synthesized and structurally characterized,namelyDy(CH3OCH3)L](1),Dy2(μ-H2O)L2](2),Zn2DyL2]ClO4·H2O(3)andNi2DyL2]ClO4·H2O(4)(H3L=N,N',N″-tris(3,5-dimethyl-2-hydroxybenzyl)-1,4,7-triazacyclononane).X-ray crystallographic analysis reveals that 1 and 2 take mononuclear and binuclear structures,respectively,and both 3 and 4 take trinuclear M-Dy(Ⅲ)-M structures(M=Zn(3),Ni(4)).Magnetic measurements showed that complexes 1 and 2 exhibited field-induced slow magnetic relaxation behaviours,while 2 had multiple magnetic relaxation processes.However,no obvious slow magnetic relaxation behaviors were observed in 3 and 4.Fluorescence analyses reveal that complexes 1~3 have narrow-band characteristic emissions of Dy(Ⅲ)ions,but no significant emission was observed in 4 because of the fluorescence quenching effect of Ni(Ⅱ)ions. |
