Synthesis and Characterization of the Monomeric Platinum(II) Complexes with 2,2’-Bipyridine Back-Bone Ligand

Abstract:

The reaction of platinum(II) complexes of [Pt(bpy-R)Cl₂] (R = H; 2,2’-bipyridine(bpy), R = 2(CH)₃; 4,4’-dimethyl-2,2’-biypridine (DM-bpy), R = 4(CH3); 3,3’-5,5’-tertamethyl-2,2’-bipyridiyl (TM-bpy), (1-3) or [Pt(1,10-phen-R’)Cl2] (R’ = H; 1,10-phenanthroline(1,10-phen), R’= 4(CH3); 3,4,7,8-tetramethyl-1,10-phenanthroline(3,4,7,8-tetramethyl-1,10-phen) (4-5) with 1,4-bis(5'-2',2"-bipyridine)benzene(bpy-Ph-bpy) affords the following monomeric platinium(II) complexes: [Pt(bpy)(bpy-Ph-bpy)]²⁺(1), [Pt(DM-bpy)(bpy-Ph-bpy)](2), and [Pt(TM-bpy)(bpy-ph-bpy)]²⁺(3), [Pt(1,10-phenanthroline)(bpy-ph-bpy)]²⁺2+(4), [Pt(3,4,7,8²⁺-tetramethyl-1,10-phen)(bpy-ph-bpy)]²⁺ (5), respectively. These complexes were characterized by NMR, IR, UV/VIS and PL spectroscopy of the complexes were elucidated. The internal quantum yields of these platinum complexes are very high (0.13 ~ 0.99) and they emit light in the blue region (360 ~ 417 nm).
