摘要/Abstract

摘要： 以1,3-双咪唑基丙烷(1,3-BIP)、1,3,5-苯三甲酸(H₃BTC)和Cu(NO₃)₂·3H₂O为原料,在溶剂热条件下合成了Cu(II)配位聚合物[Cu₂(μ₃-OH)(1,3-BIP)(BTC)]_n(SNUT-20),并用元素分析、热重分析、红外光谱、单晶X射线衍射等表征手段对配位聚合物进行了表征。单晶X射线衍射解析结果表明,配位聚合物SNUT-20是一个以四核铜簇作为次级结构单元,通过混合配体的进一步连接,形成一个3,8双节点的拓扑结构。此外,配位聚合物SNUT-20对罗丹明B(RhB)、亚甲基蓝(MB)和甲基橙(MO)表现出良好的光催化降解性能,对RhB、MB、MO的降解率分别达到了81.5%、89.4%和48.3%。

Abstract: A coordination polymer [Cu₂(μ₃-OH)(1,3-BIP)(BTC)]_n (SNUT-20) was constructed by 1, 3-di(1H-imidazol-1-yl)propane (1,3-BIP), benzene-1,3,5-tricarboxylic acid (H₃BTC) and Cu(NO₃)₂·3H₂O under solvothermal method. Its structure was confirmed by elemental analysis (EA), thermogravimetric analysis (TGA), FT-IR and single crystal X-ray diffraction. Single crystal X-ray diffraction exhibits that SNUT-20 is a 3D framework with a tetranuclear copper cluster as a secondary structural unit, which forms a binodal (3, 8)-connected topology by further ligation of mixed ligand. In addition, SNUT-20 exhibits good photocatalytic degradation performance for rhodamine B (RhB), methylene blue (MB) and methyl orange (MO), RhB, MB and MO reach 81.5%, 89.4% and 48.3% of the degradation rates, respectively.

Key words: Cu(II) coordination polymer, crystal structure, thermogravimetric analysis, photocatalytic degradation
