Abstract

A novel series of polymethylene-linked heterobinuclear complexes of polypyridine ruthenium (II)/osmium (II) complex Ru (II)(bpy) 2 Mebpy–(CH 2) n–MebpyOs (II)(bpy) 2 (bpy= 2, 2′-bipyridine and n= 2, 3, 5, and 7), 1, was prepared. The photophysical behavior was examined in various solvents. The emission spectra of 1 (excitation wavelength: 455nm) showed a nearly complete quenching of Ru II→ π*(bpy) metal-to-ligand charge transfer ( ...
