| Abstract: | The luminescence behavior of Ru(bpy)2(pq)2+, Ru(bpy)2(biq)2+, Ru(bpy)2(NO2-bpy)2+, Ru(phen)2(pq)2+, Ru(phen)2 (biq)2+, Ru(phen)2 (DMCH)2+, Ru(bpy)2(i-biq)2+ and Ru(bpy)(i-biq)22+ has been carefully studied. In no case has bona fide dual emission been observed. The reason for the previously reported dual emissions of Ru(bpy)2(NO2-bpy)2+ and Ru(phen)2(pq)2+ are discussed. |
