A Synthesis and Characterization of Pt(II) Complexes with Bipyrimidin-based Back-bone System

− In this study, new platinum complexes were synthesized utilizing the ligand of a 2,2'-bispyrimidine (bpim), 2,2'bipyridine (bpy), 5,5'-dimethyl-2,2'-bipyridine (5,5-mebpy), 5'-bromo-2,2'-bipyridine (5-brbpy), 5,5'-dibromo-2,2'-bipyridine (5,5brbpy), 4,4'-dimethyl-2,2'-bipyridine (4,4-mebpy), 4, 4'dihexyl-2, 2'Bipyridine (4,4-hebpy), 1, 10'Phenanthroline (phen), 3, 4, 7, 8'tetramethyl-1, 10'Phenanthroline (3,4,7,8-phen). In order to determine chemical structure of Synthesized platinum complexes, H(C)-NMR, UV-vis and FT-IR were used and optical physics and chemical properties were measured PL. In the case of platinum complexes, wavelength has been identified 356~421 nm. Quantum efficiency in DMSO solution was appeared 0.05~0.46.
