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。
In the method of hydrothermal synthesis, 4,4’-bipyridyl (4,4’-bpy) and 1, 4,4’-bipyridyl were used as main ligands with 5- (4-hydroxypyridylmethyl) isophthalic acid (H2L) Two novel Zn (Ⅱ) coordination polymers {[Zn (L) (4,4’-bpy) 0.5] · 2H2O} n (1) and {[Zn (L) (bpe) 0.5] · 2H2O} n (2). The structure of the complex has been characterized by single crystal X-ray diffraction and further characterized by IR, elemental analysis, PXRD and TG (thermal gravimetric analysis). The structural analysis shows that the complex 1 shows a three-dimensional triple interpenetrating network. The polymer 2 is a two-dimensional two-layer structure and is further combined into a three-dimensional parallel interpenetrating 2D → 3D spatial network. In addition, the fluorescence properties of the complexes were studied.
