The article conveys some information:
Four coordination polymers, namely, [Zn(DBT)(4,4′-dmbpy)(H2O)]n (1), [Co(DBT)(2,2′-bpy)(H2O)]n (2), [Zn(DBT)(2,2′-bpy)]n (3), [Zn(DBT)0.5(2,2′-bpy)2·(HDBT-)]n (4) (H2DBT = 2,5-dibromoterephthalic acid, 4,4′-dmbpy = 4,4′-dimethyl-2,2′-bipyridyl and 2,2′-bpy = 2,2′-bipyridyl) were synthesized under solvothermal conditions and characterized by single crystal x-ray diffraction, powder x-ray diffraction, elemental anal., IR and thermogravimetric (TG) anal. These four compounds remained stable until 150°, and the major quality loss (83-90%) occurred between 150 and 700°. In mixed ligands system, the main ligand H2DBT exhibits monodentate or bidentate bridging coordination modes and the auxiliary ligands 4,4′-dmbpy and 2,2′-bpy both possess bidentate chelate coordination modes. An objective of this study was to investigate the pivotal role of chelating ligands in the formation of low dimensional structures. As the bipyridyl ligands occupy the coordination site, compounds 1-3 all display two dimensional structures and 4 shows 1-dimensional chains, of which compounds 1 and 2 are isomorphic. The hydrogen bonds and π-π stacking work together in the formation of 3-dimensional supramol. structure of these four compounds Besides, the authors investigated their photoluminescence properties in the solid state at room temperature 1, 3 And 4 exhibited good fluorescence performance, and their strong emission peaks were located at 447 nm (λex = 285 nm) for 1, 427 nm (λex = 330 nm) for 3, and 412 nm (λex = 310 nm) for 4. The results came from multiple reactions, including the reaction of 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Recommanded Product: 4,4′-Dimethyl-2,2′-bipyridine)
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.Recommanded Product: 4,4′-Dimethyl-2,2′-bipyridine Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.
