摘要: 采用水热合成的方法,在以5-(4-羟基吡啶基甲基)间苯二甲酸(H2L)作主配体、4,4’-联吡啶(4,4’-bpy)和1,2-二(4-吡啶基)乙烯(bpe)作辅配体的条件下,得到2种新颖的Zn(Ⅱ)配位聚合物{[Zn(L)(4,4’-bpy)0.5]·2H2O}n(1)和{[Zn(L)(bpe)0.5]·2H2O}n(2)。配合物通过单晶X射线衍射的方法进行了结构分析,并进一步通过红外光谱(IR)、元素分析、PXRD和热重分析(TG)的方法进行了表征。结构分析表明配合物1展现出的是一种三维三重互穿网络;聚合物2为二维双层结构,并进一步组合成了三重平行互穿的2D→3D的空间网络。此外,研究了配合物的荧光性质。 |

Abstract: Two novel coordination polymers, {[Zn(L)(4,4'-bpy)0.5]·2H2O}n(1) and {[Zn(L)(bpe)0.5]·2H2O}n (2) (H2L=5-(4-hydroxypyridinium-1-ylmethyl)isophthalic acid, 4,4'-bpy=4,4'-bipyridine, bpe=1,2-bis(4-pyridyl)ethylene), have been hydrothermally synthesized. Both compound 1 and 2 were structurally characterized by X-ray diffraction analyses, infrared spectra (IR), elemental analyses, powder X-ray diffraction (PXRD), and thermogravimetric (TG) analyses. Compound 1 exhibits a three-dimensional (3D) 3-fold interpenetrating framework. Compound 2 has the similar 2D double-layer structure and exhibits a 3-fold parallel interpenetrated 2D→3D network motif. Meanwhile, their luminescent properties have also been investigated in detail.
