Substitution reaction with ethylenediamine of coordinated glycinate ligand in bis(ethy1enediamine)glycinatocobalt(II1) complex has been studied in the presence of photo-excited tris(2,2'-bipyridine)ruthenium(II) complex in alkaline aqueous solution (buffered around pH 12) containing 1 . 0 ~ chloride
The temperature dependence of the emission lifetime of the series of complexes Ru(bpy),(4,4'-dpb): ? (bpy = 2,2'-bipyridine, 4,4'-dpb = 4,4'-diphenyL2,2'-bipyridine) has been studied in propionitrile/butyronitrile (4:5 u/u) solutions in the range 90-293 K. The obtained photophysical parameters show
