A four-fold interpenetrated coordination polymer {[Zn-2(L)(bibp)(3)]center dot DMF center dot H2O}(n) (1) (H4L = 5,5'-(biphenyl-4,4'-diylbis(methylene)) bis(oxy) diisophthalicacid, bibp = 4,4'-bis(imidazolyl)biphenyl) has been rationally constructed, successfully solvothermally synthesized. Complex 1 was characterized by single-crystal X-ray diffraction, elemental analysis, IR spectra, powder X-ray diffraction (PXRD), and thermogravimetric (TG) analysis, and it shows a 3D four-fold interpenetrated bbf-topological framework. Luminescence studies demonstrate that 1 has high selectivity and sensitivity for pollutant Cr(VI) (CrO42- and Cr2O72-) anion and Cu(II) cation; Photocatalytic studies show that 1 exhibits great degradation activity of four organic dyes (methylene blue (MB), Rhodamine B (RhB), Methyl orange (MO) and Orange IV (OIV)). Meanwhile, the possible mechanism of the photocatalytic property has been deduced.
