Synthesis and Characterization of Platinum(II) Complexes with 2,2′-Bipyridine Derivative Supporting Ligands
Abstract:The reaction of the [Pt(bpy-R)Cl2](bpy-R: R=H (2,2′-bipyridine); R=CH3 (4,4′-dimethyl-2,2′-biypridine (DM-bpy), 3,3′-5,5′-tertamethyl-2,2′-bipyridiyl (TM-bpy)) with 1,4-Bis(5′-2′,2″-bipyridine)benzene (bpy-Ph-bpy) affords the following mono- and di-platinum complexes of [(bpy)Pt(bpy-Ph-bpy)][PF6]2 (1), [(bpy)Pt(bpy-Ph-bpy)Pt(bpy)])[PF6]4 (2), [(DM-bpy)Pt(bpy-Ph-bpy)])][PF6]2 (3), and [(TM-bpy)Pt(bpy-ph-bpy)[PF6]2 (4), respectively. These complexes were characterized by NMR, IR, UV/VIS, PL and cyclic voltammetry. The internal quantum yields of these platinum(II) complexes are very high (0.83∼0.99) and these complexes emit light at deep blue regions (373∼417 nm). The redox behavior of complexes 1 and 2 shows quasi-reversible process.
