A Coordination Polymer Constructed by Tetranuclear Copper Cluster Units and Its Photocatalytic Degradation Properties

Abstract

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.
