摘　　要：利用对苯二甲酸(1,4-H 2bdc)、N,N'-双(3-吡啶)-2,5-噻吩二甲酰胺(L)和Cu^(2+),通过水热合成法得到了一个三维金属-有机配位聚合物[Cu(L)(1,4-bdc)]·2H 2O([CX1]1[CX])。并通过元素分析、红外光谱、粉末X射线衍射和紫外-可见吸收光谱等实验方法对该配合物进行了表征。单晶结构分析表明,Cu(Ⅱ)通过1,4-bdc的羧基连接形成二维Cu-(1,4-bdc)网络,L配体连接相邻的Cu^(2+)形成一维波浪状的外消旋Cu-L链。Cu-L链与上述二维Cu-(1,4-bdc)网络连接形成三维自互穿框架。另外,研究了该配位聚合物对罗丹明B(RhB)、龙胆紫(CV)、亚甲基蓝(MB)和甲基橙(MO)的光催化降解性质以及对过氧化氢(H 2O 2)和亚硝酸钾(KNO 2)的电催化活性。A 3D metal-organic coordination polymer[Cu(L)(1,4-bdc)]·2H 2O([CX1]1[CX])was synthesized by hydrothermal method using terephthalic acid(1,4-H 2bdc),N,N'-bis(3-pyridine)-2,5-thiophene dicarbonamide(L)and Cu^(2+).The complex was characterized by elemental analysis,infrared spectrum,powder X-ray diffraction and UV-Vis absorption spectrum.Single crystal structure analysis shows that Cu^(2+)connected by 1,4-bdc anions to form a 2D Cu-(1,4-bdc)network.The L ligand connects the adjacent Cu^(2+)to generate a 1D wave like racemic Cu-L chain.The Cu-L chain is connected with the 2D Cu-(1,4-bdc)network to form a 3D self-interpenetrating framework.In addition,the photocatalytic degradation properties of the coordination polymer for rhodamine B,gentian violet,methylene blue and methyl orange and its electrocatalytic activities for hydrogen peroxide and potassium nitrite were studied.
