RETRACTED: Mixed-ligand strategy affording two new metal-organic frameworks: Photocatalytic, luminescent and anti-lung cancer properties

Abstract

Abstract Mixed-ligand strategy afforded two new metal-organic frameworks (MOFs), namely [Ni(L)0.5(4,4′-bipy)0.5(H2O)2]n (1) and [Zn2(L)(bpp)2]n (2) (H4L = 1,3-di(3′,5′-dicarboxylphenyl)benzene, 4,4′-bipy = 4,4′–bipyridine and bpp = 1,3-di(4-pyridyl)propane), which were further characterized by elemental analyses, powder X-ray diffraction analyses and single crystal X-ray diffraction analyses. Compound 1 features a 4-fold interpenetrated 3D framework with (3,4)-connected dmd-type topology, and compound 2 features a 3D complicated framework with 4-connected topology. Moreover, the photocatalytic activity of compound 1 for the degradation of methyl blue (MB) and luminescent property of compound 2 were investigated in detail. In addition, the anti-lung cancer activities of both complexes have been evaluated via the MTT assay against three human lung cancer cells A549, H1299 and PC9.
