DMA mismatch detection by resonance energy transfer between ruthenium(II) and osmium(II) tris(2,2′-bipyridyl) chromophores

Abstract:

Octahedral tris-chelate complexes [M II(bpy) 3] 2+ (M = Ru or Os, bpy = 2,2′-bipyridyl), covalently attached to the 3′- and 5′phosphates of two oligonucleotides, are juxtaposed when hybridized contiguously to a fully complementary DMA target. Visible metal-to-ligand charge-transfer (MLCT) excitation of the [Ru II(bpy) 3] 2+ unit leads to resonance energy transfer to the MLCT state of the [Os II(bpy) 3] 2+ moiety, with the energy transfer efficiency depending on the degree of hybridization. Th...
