本文以间苯二吡啶(1,3-dpb)和4,4′-二苯醚二甲酸(H2oba)为配体,溶剂热合成了一个二维锌配位聚合物{[Zn(oba)(dpb)].H2O}n(1),对其进行了红外,热重,粉末单晶衍射等表征,配合物属于三斜晶系,空间群C2/c。相邻的Zn(Ⅱ)离子通过连接oba2-和dpb形成二维波浪形面,两个相邻的面相互互锁形成2D→2D的结构,并且面与面之间存在氢键。两组2D→2D的结构通过π-π作用进一步形成双层的二维超分子网络。此外,本文也研究了配合物的荧光性能。
In this paper, a two-dimensional zinc coordination polymer, {[Zn (oba) (1, 3-dpb) and 4,4’-diphenyl ether dicarboxylic acid dpb)]. H2O} n (1) were synthesized and characterized by IR, TG and powder single crystal diffraction. The complexes belong to triclinic system with space group C2 / c. Adjacent Zn (II) ions form a two-dimensional wavy surface by connecting oba2- and dpb. Two adjacent surfaces interlock with each other to form a 2D → 2D structure, and there is hydrogen bond between the surface and the surface. Two sets of 2D → 2D structures further formed a two-dimensional two-dimensional supramolecular network through π-π interaction. In addition, the fluorescence properties of the complexes were also studied.
