| 中文摘要: |
| 基于π...π作用构建而成的一种Cu(II)的3D超分子配位聚合物[CuL(phen)]n (1)(H2L = 5-(咪唑甲基)间苯二甲酸,phen = 1,10-菲咯啉)已通过水热方法得到,并利用元素分析、粉末XRD、红外光谱、紫外光谱、热重分析(TGA)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P-1,在1中,作为桥基配体的L2?阴离子将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,配合物1的光化学性质也得到了研究。 |
| 英文摘要: |
| One 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), [CuL(phen)]n (1), has been obtained under hydrotheremol condition and characterized by elemental analysis, powder X-ray diffraction (PXRD), IR spectra, Uv/vis spectra, thermal gravimetric analyses (TGA) and single-crystal X-ray diffraction. It crystallizes in triclinic crystal system with P-1 space group, which show 3D supermolecular framework. In complex 1, L2? anions, 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 between the neighboring imidazolyl group to lead to double layers, meanwhile, two adjacent phen ligands from different 2D double layers in parallel mode via face-to-face π...π interaction further stabilize the 3D network. In addition, the photochemical property of complex 1 has also been investigated. |
