摘要: 以羧酸配体2,2'-(1,4-亚苯基双(亚甲基))双(硫二基)二苯甲酸(H2L1)和2,2'-(2,3,5,6-四甲基-1,4-亚苯基)双(亚甲基)双(硫二基)二苯甲酸(H2L2)分别与金属盐反应,通过溶剂热方法合成了3个配位聚合物:{[Ni(L1)(H2O)4]·2H2O}n (1)、[Zn(L1)(DMA)2]n (2)和[Co(L2)(DMF)2]n (3),其中DMA=N,N-二甲基乙酰胺,DMF=N,N-二甲基甲酰胺。对配合物1~3进行了单晶X射线衍射、元素分析、红外光谱、热重分析、粉末X射线衍射和固体紫外可见光谱测试和表征。单晶X射线衍射表明:3个配合物均为一维锯齿形链状结构,并通过氢键作用形成三维骨架,且配体均表现为反式构象。此外,对配合物2固态荧光性质进行了研究。 |

Abstract: Three coordination polymers (CPs), namely, {[Ni(L1)(H2O)4]·2H2O}n (1), [Zn(L1)(DMA)2]n (2), and [Co(L2)(DMF)2]n (3) (DMA=N, N-dimethylacetamide, DMF=N, N-dimethylformamide) were synthesized based on dicarboxylate ligands 2, 2'-(1, 4-phenylenebis(methylene))bis(sulfanediyl)dibenzoic acid (H2L1) and 2, 2'-(2, 3, 5, 6-tetramethyl-1, 4-phenylene)bis(methylene)bis(sulfanediyl)dibenzoic acid (H2L2) under solvothermal conditions. Complexes1-3 have been structurally characterized by single-crystal X-ray diffraction analyses and characterized by elemental analysis, infrared spectra, thermogravimetric analysis, powder X-ray diffraction, and solid-state UV-Vis spectrum. They have zigzag chain structures and the ligands all display anti-conformation. Besides, the chains in1-3 further form 3D frameworks by hydrogen bonding interactions. Furthermore, the solid-state fluorescence property of2 was investigated. |
