摘要

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.%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-CHrtacnTs2)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.
