Abstract A coordination unsaturated copper (II) coordination polymer, [Cu(tptc)0.5(bpy)(H2O)]n (1), was constructed from the mixed ligands of p-terphenyl-2,2'',5'',5'''-tetracarboxylate acid (H4tptc) and 1,3-bis(imidazol-1-ylmethyl)benzene (bimb) under hydrothermal condition. Structural analysis revealed that CP 1 is a 2D 4-connected {32∙62∙72} kgm polymeric sheet, which can be further expanded into 3D supramolecular through hydrogen bonds. The coordination unsaturated central Cu(II) ions endow the CP 1 open metal sites, displaying good electrochemical reversibility as well as high efficiency in photocatalytic degradation of methylene blue (MB) under UV irradiation.

一种配位不饱和铜(II)基配位聚合物的晶体结构、电化学可逆性和光催化降解

摘要 配位不饱和铜 (II) 配位聚合物 [Cu(tptc)0.5(bpy)(H2O)]n (1) 由对三联苯-2,2'',5'' 的混合配体构建而成， 5'''-四羧酸（H4tptc）和1,3-双（咪唑-1-基甲基）苯（bimb）在水热条件下。结构分析表明，CP 1 是 2D 4-connected {32∙62∙72} kgm 聚合物片，可以通过氢键进一步扩展为 3D 超分子。配位不饱和中心Cu（II）离子赋予CP 1 开放金属位点，显示出良好的电化学可逆性以及在紫外线照射下光催化降解亚甲基蓝（MB）的高效性。
