采用水热法合成了一种基于π…π作用构建而成的Cu(Ⅱ)的3D超分子配位聚合物[Cu L(phen)]n(1)(H2L=5-(咪唑甲基)间苯二甲酸,phen=1,10-菲咯啉),并利用元素分析、粉末XRD、红外光谱、紫外光谱、热重分析和单晶X-衍射分析的方法对其结构进行了表征。结构分析表明,配合物1的单晶为三斜晶系、空间群为Pī,在1中,作为桥基配体的阴离子L2-将Cu(II)离子连接起来构成了2D网络(Cu3L3)n,相邻的2D层又通过咪唑环间的π…π作用连接成了双层结构,这些双层结构又被处于平行分布的菲咯啉环间的π…π作用延展为稳定的3D网络。此外,本文还研究了配合物1的光化学性质。
A novel 3D supramolecular coordination polymer of Cu (Ⅱ) [Cu L (phen)] n (1) (H2L = 5- (imidazolylmethyl) Isophthalic acid, phen = 1, 10-phenanthroline) were synthesized and characterized by elemental analysis, powder XRD, IR, UV, TG and single crystal X-ray diffraction. The structural analysis shows that the single crystal of complex 1 is triclinic and the space group is Pī. In 1, the anion L2-Cu (II), which is the bridge ligand, connects the Cu (II) ions to form a 2D network (Cu3L3) n , And the adjacent 2D layers are connected to form a two-layer structure through the π ... π interaction between the imidazole rings. These two-layer structures are further extended to a stable 3D network by the π ... π interaction between the parallelly distributed phenanthroline rings. In addition, we also studied the photochemical properties of complex 1.
