摘　　要：利用3-(4-羧基-苯氧基)-1,5-苯二甲酸(H_(3)L)为配体通过溶剂热法合成了一个锰基配位聚合物:[Mn_(2)(L)(DMF)]_(n)(DMF=(N,N'-二甲基甲酰胺),并利用X-射线单晶衍射测试分析对其结构进行了表征。(X(-射线单晶衍射分析结果表明,该锰基配位聚合物属于单斜晶系,(P2_(1/c);光催化降解实验结果表明,该配位聚合物对亚甲基蓝(MB)、罗丹明B(RhB)及甲基紫(MV)三种有机染料均具呈现出较好的光催化降解能力,其光催化降解过程较好地符合准一级动力学方程。A Mn-based coordination polymer,named[Mn_(2)(L)(DMF)]_(n)(DMF=N,N’-dimethylformamide,was synthesized by solventthermal method using 3-(4-carboylphenoxy)-1,5-benzodicarboxylic acid (H3L) as the ligand and was characterized by X-ray single crystal diffraction analysis.TheX-ray single crystal diffraction analysis result shows that Mn-based coordination polymer belongs to the monoclinic crystal system,P2space group.The photocatalytic degradation experimental results show tha the coordination polymer has good photocatalytic degradation ability for MB,RhB and MV and the photocatalytic degradation process conforms to the quasi-first-order kinetic equation well.
