Abstract

A novel tetrazole-containing triphenylamine-based MOF {TBA[Cu2(TPA)]}·CH3CN (Cu–TPA; TBA = tetrabutylammonium cation) has been solvothermally synthesized by the reaction of CuCl2·2H2O, tris(4-(2H-tetrazol-5-yl)phenyl)amine (H3TPA) and (TBA)4[W10O32] and structurally characterized by IR spectrum, UV–Vis spectrum, fluorescence analysis, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. More interestingly, Cu–TPA exhibits remarkable heterogeneous photocatalytic property and promotes the oxidative CC coupling reaction under mild conditions. The high catalytic efficiency, high stability and good recyclability of the photocatalyst Cu–TPA demonstrate the superiority of the tetrazole-containing triphenylamine-based MOF over homogeneous systems and other noble-metal-catalyzed methods.
