Abstract
- Two novel 3D functional CPs based on the flexible 4-(4-carboxylphenylmethylthio)benzoic acid ligand have been successively synthesized. Complex 2 that is composed of Co(II), 4,4′-H 2 cpmb and 1,3-Hbib ligand displays good photo-degradation and adsorption properties for the organic dyes. Two new coordination polymers (CPs) based on transition metals, namely [Ni 2 (4,4′-cpmb) 2 (4,4′-bbibp) 2 (H 2 O) 4 ] n (1) and [Co(4,4′-Hcpmb)(1,3-bib)] n (2) (flexible 4,4′-H 2 cpmb = 4-(4-carboxylphenylmethylthio)benzoic acid, rigid 4,4′-bbibp = 4,4′-bis(benzoimidazo-1-ly)biphenyl and 1,3-Hbib = 1,3-bis(1-imidazo-1-ly)benzoic acid), have been designed and successfully synthesized under solvothermal conditions, which have been characterized by elemental analysis, infrared spectra, thermogravimetric (TG) analysis, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis reveals that 1 features a 3D supermolecular structure in ABAB mode by H bonds (O⋯H⋯O) with a 2-fold interpenetrating sql topology framework and 2 displays a 3D supermolecular framework by H bonds (O⋯H⋯O) with a rarely fes topology. Moreover, the photo-degradation and dye adsorption properties of CPs 1 – 2 have been investigated. Importantly, 2 shows good photo-degradation and dye adsorption properties. [ABSTRACT FROM AUTHOR]
