| 摘要: 合成了一种多齿的三脚架配体：三（2-（4，7-二甲磺酸基-1，4，7-三氮杂环壬烷基）甲基苄基）胺，即N（CH2-o-C6H4-CH2-tacnTs2）3（L），其中Ts=tosyl。它包含3个1，4，7-三氮杂环壬烷连接在三苄基胺的邻位。该配体在高氯酸钠存在情况下结晶，自组装得到4个钠离子形成的四面体结构晶体：[Na4（L）（CH3CN）（ClO4）4（H2O）3]n。该晶体结构用X射线单晶衍射、粉末衍射、红外光谱和热重分析表征，并用紫外吸收和荧光对其光学性质进行表征。 |

| Abstract: A multidentate tripodal ligand,tris (2-((4,7-ditosyl-1,4,7-triazonan-1-yl) methyl) benzyl) amine,namely N (CH2-o-C6H4-CH2-tacnTs2)3(L,Ts=tosyl),which contains three triazacyclononane arms linked to the ortho positions of a tris (xylyl) amine scaffold,was synthesized.It stabilizes a[Na4(ClO4)4]tetrahedron cluster,which is rarely reported in the literature.The resulted complex has the formula of[Na4(C84H102N10O12S6)(CH3CN)(ClO4)4(H2O)3]n.This tripodal tris-tacn complex has been characterized by single crystal X-ray diffraction,powder X-ray diffraction,infrared spectroscopy and thermal thermogravimetric analysis.UV-visible absorption spectrum and fluorescence spectrum were measured to characterize the optical properties of the complex. |
