摘要：

The reaction of the [Pt(bpy-R)Cl(2)](bpy-R: R=H (2,2'-bipyridine); R=CH(3) (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)][PF(6)](2) (1), [(bpy)Pt(bpy-Ph-bpy)Pt(bpy)D[PF(6)](4) (2), [(DM-bpy)Pt(bpy-Ph-bpy)])][PF(6)](2) (3), and [(TM-bpy)Pt(bpy-ph-bpy)[PF(6)](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 similar to 0.99) and these complexes emit light at deep blue regions (373 similar to 417 nm). The redox behavior of complexes 1 and 2 shows quasi-reversible process.
