摘要
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 Copper 3D supramolecular coordination polymer constructed by π … π interaction based on a flexible 5-（ imidazol-1-ylmethyl） isophthalic acid（ H2L） and ancillary nitrogen-containing ligands 1,10-phenanthroline（ phen）,[Cu L（ phen） ]n（ 1）,had been synthesized under hydrotheremol condition and characterized by elemental analysis,PXRD,IR,UV-Vis,TGA and single-crystal X-ray diffraction. The structural analysis showed that the coordination polymer 1 crystallizes in triclinic crystal system with Pī space group. In complex 1,anions L2-,as a bridging ligand,connect Cu（ II） ions to form 2D layers（ Cu3L3）n,then the adjacent layers are futher associated together through π…π interaction of neighboring imidazolyl group to form double layers. Futhermore,two adjacent phen ligands from different 2D double layers in parallel mode are extended to the stable 3D network via face-to-face π…π interaction. In addition,the photochemical property of complex 1 had also been investigated.
