溶剂热条件下采用Cd(NO3)2.4H2O、对苯二甲酸和三乙烯二胺作为反应物合成出一个具有二维骨架结构的配位聚合物{Cd(bdc)(dabco)(DMF)].2H2O}n(1),并采用元素分析、红外光谱、差热分析和X-射线单晶衍射进行了研究及表征。晶体结构分析结果表明:对苯二甲酸离子(bdc)将Cd(Ⅱ)离子连接成一维链,相邻链之间进一步被三乙烯二胺(dabco)构筑成二维层状结构。沿c轴方向,垂直于二维层状结构中存在大小为0.74 nm×0.65 nm的一维通道。荧光谱图表明常温固态下配合物1发射蓝色荧光,荧光寿命为38.2 ns。
Cd (bdc) (dabco) (DMF)] was synthesized with Cd (NO3) 2.4H2O and terephthalic acid and triethylenediamine as reactants under solvothermal conditions. 2H2O} n (1) were synthesized and characterized by elemental analysis, infrared spectroscopy, differential thermal analysis and single crystal X-ray diffraction. The results of crystal structure analysis show that the phthalic acid ion (bdc) links Cd (Ⅱ) ions into one-dimensional chain, and the adjacent chains are further double-layered by dabco. In the c-axis direction, there is a one-dimensional channel with a size of 0.74 nm × 0.65 nm perpendicular to the two-dimensional layered structure. Fluorescence spectra showed that complex 1 emits blue fluorescence at room temperature in solid state, and the fluorescence lifetime is 38.2 ns.
