Abstract

Abstract: Five substituted-2, 2′-bipyridine ligandsL, (4-( p -methylphenyl)-6-phenyl-2, 2′-bipyridine (L1 ), 4-( p -bromophenyl)-6-( p -bromophenyl)-2, 2′-bipyridine (L2 ), 4-( p -bromophenyl)-6-phenyl-2, 2′-bipyridine (L3 ), 4-phenyl-6-( p -bromophenyl)-2, 2′-bipyridine (L4 ), and 4-( p -fluorophenyl)-6-( p -fluorophenyl)-2, 2′-bipyridine (L5 ) were synthesized by stepwise formation. Reaction of cis -[RuCl2 (bpy)2 ]⋅2H2 O or cis -[RuCl2 (phen)2 ]⋅2H2 O and the substituted-2, 2′-bipyridine ligands in the presence of KPF6 afforded the corresponding cationic polypyridine-ruthenium complexes of the type [(bpy)2 Ru(L )](PF6 )2 (bpy = 2, 2′-bipyridine, 1 –5 ) or [(phen)2 Ru(L )](PF6 )2 (phen = 1, 10-phenanthroline, 6 –10 ), respectively. All complexes have been spectroscopically characterized by UV–vis, luminescence, and electrogenerated chemiluminescence. The structures of1 ⋅CH3 COCH3, 3 ⋅CH3 COCH3, 5 ⋅2CH3 COCH3, 6, 8, 9, and10 have been determined by single-crystal X-ray diffraction. Abstract :
