以柔链配体癸二酸（C10H18O4）为第一配体、邻菲啰啉（phen）为第二配体合成了三个过渡金属配合物[Mn2（C10H16O4）2（phen）4（H2O）].4H2O（1）、[Cu（C10H16O4）（phen）（H2O）].3H2O（2）、[Cd（C10H16-O4）（phen）].3H2O（3）.用元素分析、红外光谱、热重分析等手段表征了配合物;用单晶X射线衍射测定了配合物的结构;其中配合物1和2为癸二酸根桥连的双核结构,配合物3为含有双核节点的配位聚合物.在配合物1中发现了水分子的二聚体,在配合物2中则发现了一维水链,并在配合物3中发现了四元环的六聚水,这些片断通过氢键作用稳定地存在于晶格空隙中,这三种配合物均含有多孔的无限隧道.用溴化乙锭荧光探针法测试了三个配合物对EB-DNA复合体系的荧光猝灭效应,实验结果显示三个配合物均能使EB-DNA复合体系的荧光发生不同程度的猝灭,由此推测配合物均与DNA发生了不同程度的插入作用,其中配合物1的插入作用最强.     

高藜芦酸邻菲咯啉铽(Ⅲ)配合物的合成、晶体结构及荧光光谱

A terbium(Ⅲ) complex [Tb2(NO3)(DMPA)5(phen) 2] (HDMPA=homoveratric acid, C12H12O4; phen=1,10- phenanthroline), was synthesized and characterized by elemental analysis, IR and TG-DTG. Its crystal structure was determined by single crystal X-ray diffraction method. The complex, C74H71N5O23Tb2, crystallizes in the monoclinic system, space group P21/n. The emission spectrum of complex, there are four main peaks, 489, 545, 584 and 622 nm, respectively, corresponding to 5D4→7F6, 5D4→7F5, 5D4→7F4 and 5D4→7F3 transitions of Tb(Ⅲ). The intensity of 5D4→7F5 is much stronger than others.
